StartMenuExperienceHost.exe Knocks ReliMon Over

2 Comments

When searching for Windows blog topics, I occasionally drop in on Reliability Monitor (aka ReliMon). FYI, it’s actually a special version of the more general-purpose Performance Monitor (PerfMon). This morning, I saw what I can only describe as a bad-to-worse stability index chart. See the lead-in graphic. Upon examination, I concluded that StartMenuExperienceHost.exe knocks ReliMon over with daily errors. Ouch!

Handling StartMenuExperienceHost.exe Knocks ReliMon Over

Digging into the details, I see this element present every day (multiple times on some days) for 16 of the past 17 days. That’s a new personal record for me, and it’s interesting. Why? Because this system hasn’t been giving me any obvious trouble, repeat SMEH errors notwithstanding. (Hope that abbreviation is obvious…)

So naturally I went looking for enlightenment about SMEH and the related MoBEX error that occurs for each instance in the detail page. Unsurprisingly, I found a registry hack to address the issue at TenForums.com from well-known VIP member Samuria. Apparently, it involves a well-known permissions inheritance issue for values inside the

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders

key. I’ve applied the fix Samuria recommends, and will observe ReliMon over coming days to see if it helps.

The Enduring Value of Internet Community

Though one must exercise caution in picking up and running with fixes from the Internet, there are gradations of trust and merit in play, too. Because I’ve been an active member of TenForums for years and have seen many, many useful tips from Samuria over that entire interval, I’m comfortable with following his advice. That makes this a “safe fix” IMO. But if you have a recent backup handy, and know how to restore it, you can always get back to where you started. That’s my fallback position, and I’m sticking with it. Cheers!

I’ll keep you posted as I see if this helps … or not. Stay tuned!

Sept 13 follow-up #1: No dice, but…

I got a comment from fellow TenForums VIP OldNavyGuy that told me two things: he tried the reghack and it didn’t work for him. He also build a new user profile and moved over to that, then killed the old one. He reports that did away with the ongoing torrent of StartMenuExperienceHost.exe errors. I’ll try it sometime, and see.

Fast UFDs Need Fast USB Ports

Leave a comment

I just learned something amazing. I’ve long known that performance depends greatly on USB port selection. Indeed I posted about this nearly two years ago to the day: USB-C Port Choice Really Matters. Amusingly, it wasn’t until this morning that I figured out this caution applies to USB-A ports as well. Indeed, fast UFDs need fast USB ports for them to deliver their fullest capabilities. The speed difference is shocking, too: more than 20X faster for large read/writes; 2-10X faster for small ones. Let me show you…

CDM Shows That Fast UFDs Need Fast USB Ports

Check out the lead-in graphic at right. It shows CystalDiskMark (CDM) results for the same Kingston Data Traveler Max 256GB UFD I just had delivered from Amazon yesterday. It’s rated at 1,000 MB/s read, and 900 MB/s write on that purchase page. As you can see, CDM reports better numbers than those for queue depth of 8 on a 1 GiB object, and somewhat less for a queue depth of 1.

What’s fascinating, however, is the results shown on the left. These popped up in a pretty new ThinkPad T14s Gen6 Copilot+ PC I received from Lenovo last month. As the user manual confirms, both of its USB-A connectors top out at 5 Gbps, which makes them plain-vanilla USB 3.0 (aka USB 3.2 Gen1). As you can see given that I’m testing the same device in two different USB-A ports, the difference is down to the port. And that difference is MAJOR!

Here’s a Potential Workaround

You can purchase a dongle/adapter that is female USB-A on one side, and male USB-C on the other. It will let you plug a fast USB-A UFD into a presumably faster USB-C port. I bought a 2-pack of these from Amazon back in 2021. You can see there’s some pass-through loss (compare upper right results, and you’ll see what I mean) when taking this approach. But gosh! It’s still MUCH faster than a 5Gpbs connection. ‘Nuff said.

If you buy a fast UFD and your laptop or PC has only 5 Gbps USB-A ports, spend the extra $5-6 that a USB-A to USB-C adapter will cost. You’ll get a major performance boost as a result, even if it’s not as good as a native 10 Gbps USB-A port. Cheers!

Windows App Will Replace Remote Desktop

Leave a comment

I’m finally starting to get some clarity on the emerging Windows App, now out in preview. That clarity comes courtesy of a nice story from Martin Brinkmann at gHacks entitled “The Windows Windows app is real — replacing remote desktop app.” But I’ve got a problem with this tool –identical to the problems I had with the Teams (Work or school) version. I don’t have a qualifying MSA among the half-dozen or so I have set up. So, even though the Windows App will replace Remote Desktop, I’m still unable to use it. Sigh.

How Soon the Windows App Will Replace Remote Desktop?

Having been through this with Teams earlier this year, I  imagine Windows App will follow a similar trajectory. MS must eventually loosen its exclusive requirement for an Entra related MSA. Why say this? Because of 2 inescapable facts:

  1. The population of personal MSAs dwarfs that for the other kind
  2. Unless MS adds personal MSAs, it can’t replace Remote Desktop

All this said, the Windows App is now available in preview form. MS has various Learn assets for the program but none of them provides information about timing just yet. The best place to start is with What is Windows App? It leads to other useful info, too. My best guess is that this will be another element that distinguishes the 24H2 Windows 11 release from its predecessors.

Finding the Windows App…

Because “Windows app” is a generic term, and “Windows App” is the name of an MS Store object, some sleight of hand is needed to run it down. Best to search the store with “Windows App” (including caps) enclosed in quotes.

According to the MS Learn article Link to your app, you can synthesize the Store URL for an app by appending its Id string to this base string:

https://apps.microsoft.com/store/detail/

WinGet will happily provide that ID using either its list or show capabilities. Here again, I had to enclose “Windows App” in quotes to make this work, to wit:

As you can see, WinGet says the ID = 9N1F85V9T8BN, so that URL should be https://apps.microsoft.com/store/detail/9N1F85V9T8BN. Let’s see…

Works! Now, all I have to do is get a “real” Work or school MSA so I can use the gosh-darned thing. But that’s another kettle of fish entirely, here in Windows-World. Stay tuned.

Windows 10 Beta Access Proves Elusive

Leave a comment

On June 4, MS announced it was (re)opening the Beta Channel for Windows Insiders on Windows 10. So I stood up a Windows 10 VM on my trusty Lenovo ThinkPad P16 Gen1 Mobile Workstation to try this out. Bizarrely, after joining the Beta Channel the next update informed me it was loading a Windows 11 Beta version. Indeed, either I couldn’t figure out how to get the actual Windows 10 Beta to download and install, or that version was mislabeled. That’s why I aver that Windows 10 Beta access proves elusive.

If Windows 10 Beta Access Proves Elusive, Then What?

As you can see in the lead-in graphic, after I “got away” from an apparent Windows 11 beta install, I did manage to get into the Windows 10 Insider Preview Channel. Right now, it has the same release as does the Beta Channel anyway (see Aug 22 blog post).

From that vantage point, and that build number (19045.4942) I was then able to “upgrade” myself to the Beta Channel. This is apparently a case where if a single-step approach doesn’t work, a more tentative two-step (Insider Preview first, then Beta) channel changing strategy does. Go figure!

Little by Little, Step by Step

If you can’t get where you need to go in Windows in one fell swoop, incremental progress will have to do. As you can see in the closing screencap, the test VM is now in the Beta Channel and running the associated most current Windows 10 release (likewise 19045.4942, which is how I could make the switch both quickly and easily).

Enrolling in Insider Preview, then switching to Beta works like a charm.

Here in Windows-World, even if the obvious method doesn’t seem to work, a less direct approach can still get you where you want or need to go. I’d call this another case in point.

Reinstall Solves Nvidia Driver Issue

Leave a comment

This morning, I noticed a new GeForce driver for the RTX 3070 Ti on my production system via the NVIDIA app. Perforce I installed same. Then the screen flashing started: on and off, and on and off, and … you get the idea. I’ve been here before, but usually when an old driver needs replacing. I tried to roll back (but the option didn’t light up) so I used the REINSTALL facility you see at the upper right of the lead-in graphic. I’m happy to report that such a reinstall solves NVIDIA driver issue. The blinking/flashing is fixed. Good-oh!

Why Reinstall Solves Nvidia Driver Issue

When a graphics driver misbehaves  — as in going into blink mode — it’s usually because the driver itself is messed up. Or it might be that communications between the driver and the device aren’t working properly. Either way, something needs to change.

Ordinarily I’d use the rollback facility on the Driver tab for the RTX 3070 Ti to revert back to the previous version. But, as you can see in the next screencap, the “Roll Back Driver” button is greyed out. Alas, that means there’s nothing to roll back to. Looks like the new NVIDIA app doesn’t keep old driver versions around. What to do?

Because it’s greyed out, I can’t use Roll Back Driver.

Fortunately, as you can see in the lead-in graphic, the NVIDIA app offers a REINSTALL option for the current driver. Because the installed version was blinking I figured I had nothing to lose by giving REINSTALL a try. So I did just that.  Just to make sure everything got replaced, I also checked the installer’s Clean Installation option. And fortunately for me, it worked!

The desktop is back to normal, and the blinking is behind me now. All’s well that ends well in Windows-World, especially when it comes to misbehaving graphics drivers.

MS Store Splits Updates & Library

Leave a comment

You can tell it’s been a busy week. I just now tried out the new Microsoft Store organization as of version 22407.1401.2.0. In that iteration, MS Store splits updates & library in the left-hand menu, as you can see in the lead-in graphic (lower left). The item is actually labeled Downloads when none are pending. You can see a down-arrow from the cloud symbol in that screencap (above Library) to show that updates are available. This makes it faster and easier to get to updates inside the Store, and to know when to do so. I like it!

When MS Store Splits Updates & Library…

Alas, it also did away with its settings controls inside the Store. No more three dots to the right of the user icon. I couldn’t even get Microsoft Store itself to come up inside the Microsoft Store. Instead I had to use WinGet list “Microsoft Store” inside Windows Terminal/PowerShell to show me which version was running on this Canary Channel PC:

Unable to access “About” info for the MS Store, I got it from WinGet instead.

This is a good change. And I also realized that because the Microsoft Store is pre-installed on modern Windows versions, there’s no “store page URL” available for that app itself. Instead, uninstallling and/or reinstalling requires some PowerShell magic, as explained in this MS Answers tutorial (from the always helpful Andre Da Costa).

That’s probably why I also had to turn to PowerShell and WinGet to obtain the current Microsoft Store version number, too. That’s the kind of thing that keeps life interesting, here in Windows-World.

NVIDIA Driver Forces POPCNT Support

2 Comments

Hey! We’ve known it was coming for some time now. In February 2024, Tom’s Hardware reported: “Microsoft’s PopCnt restriction appears to be unbreakable.” This CPU instruction is part of the SSE4.2 Instruction set for Intel processors. It’s SSE4.2a for AMD CPUs, and also present in Snapdragon X as well. Indeed it’s been part of the computing landscape since 2008 for Intel, circa 2009-2010 for AMD, and since inception for ARM (including Copilot+ PCs). But now, with the introduction of version 555, NVIDIA driver forces POPCNT support. How so? Check the lead-in graphic. Windows 10 and 11 systems that lack POPCNT support will BSOD if they install this latest GPU driver version. Ouch!

Sussing Out NVIDIA Driver Forces POPCNT Support

You can read about this in the NVIDIA release notes for 555 (source of the lead-in graphic). It’s entitled “EOL Windows driver support for older CPUs without POPCNT instruction.” That pretty much says it all. The note recommends using Sysinternals Coreinfo to check for POPCNT support. (Indeed, it worked to show such support on the Lenovo ThinkPad T14s Copilot+ loaner PC.)

But on Intel and AMD PCs, I found it easier to use Franck DeLattre’s excellent CPU-Z tool to look for the SSE4.2 (or SSE4.2a) instruction set instead. The ARM version of CPU-Z is less than helpful in providing POPCNT info because it doesn’t natively map to any ARM instruction set. Here’s what comes up on my ancient i7 SkyLake desktop (running Windows 10 for lack of CPU support).

Note the “Instructions” entry that reads SSE4.2 (bottom of “Processor” block): that’s what we’re looking for, when using this tool to check for POPCNT support on Intel CPUs. WindowsLatest reports that CoreInfo doesn’t work reliably on all systems, and recommends other CPU check tools besides CPU-Z. Be sure to check it out for those details if one or the other of these tools doesn’t cut it on your rig.

Older PCs: Avoid NVIDIA 555

The real takeaway from this news is that owners of older PCs whose CPUs don’t support POPCNT should avoid updating to NVIDIA driver versions number 555 or greater. Otherwise, they’ll have to boot into WinRE, and use DISM at the command line to uninstall that driver to end a BSOD loop on that machine. You’ve been warned! I’d be inclined to take this as a early indicator that a hardware refresh should be in your future, too…

Finally Windows 10 Copilot Is Here

Leave a comment

I’ve been waiting for some time for the Copilot facility to make its way onto my Windows 10 desktops since last November. That’s when MS made the first Preview available to versions 21H2 and 22H2. Since then, I’ve read numerous other announcements of its increasing spread and reach into the dominant Windows desktop OS. But not on my PCs or VMs, it seems. That all changed when Copilot hit the MS Store a couple of months back. Now, finally, Windows 10 Copilot is here for anybody who wants it — including me!

Finally Windows 10 Copilot Is Here
… and RUNNING!

I’m absolutely delighted to be able to interact with Copilot in a clear and well-understood way. That it’s now “just another app in the Store” makes it ever so much more approachable and easy to install and run. The only minor glitch I’ve run into from this Copilot avatar is obtaining version info. There’s supposed to be an about field under the App Settings heading. But I get an Edge page of app info instead, sans version number.

That’s OK though: I can visit the app’s Store page or use WinGet list Copilot to elicit that info. As you can see, the latter command provides that info on demand, no scrolling nor much reading needed:

There it is in clear form: my Win10 production PC is running the latest and greatest 1.0.4.0 version of Copilot (from the MS Store).

Copilot on 10 versus 11

So far, I really can’t tell much (or any) difference between Copilot on the two prevailing Windows OS versions.  Even on the brand-new Copilot+ PC that showed up at my doorstep yesterday: a ThinkPad T14S Gen 6 there aren’t easy, available ways to take advantage of the unit’s AI-oriented CPU, GPU and NPU capabilities just yet. Can’t wait to see how that will all unfold later this year, though, when 24H2 comes out “for real” — and hopefully, with readily usable Copilot+ features and functions. We’ll see: I’m certainly standing by!

WinGet Updates PowerShell, Error Aside

Leave a comment

I have to chuckle. There’s a new PowerShell 7.4.4 out. I just used WinGet to update my production PC and it applied the update package. But when it got the end of the update, it reported “Installation abandoned” and ended the WinGet update session. Because 7.4.4 came when I closed, then re-opened, Windows Terminal it looks like WinGet updates PowerShell, error aside. You can see the sequence in the lead-in graphic.

WinGet Updates PowerShell, Error Aside

Notice that a “Cancelled” item shows up below the “Installation abandoned” notification. I’m guessing this last item refers to jumping out of the WinGet update sequence, because you see a normal command line prompt (spiffed up, thanks to Oh-My-Posh).

And sure enough, running WinGet upgrade –all –include-unknown finishes up the remaining items that appeared below PowerShell in the update list. In the next screencap I show a two-pane Windows Terminal session. On the left, you see the sequence of update packages installed; on the right, you see the PS Version is now 7.4.4.

To the left you see WinGet at work; to the right a newly-opened PS session says it’s v7.4.4. [Click image for full-sized view.]

One more thing: the final item in the upgrade sequence on the X1 Extreme was Winget itself (which appears as Microsoft.AppInstaller inside the upgrade list). At its conclusion, WinGet closes things out a bit more reasonably. It says:

Successfully installed. Restart the application to complete the upgrade.

Cancelled

I think that confirms my suspicion that the cancelled item refers to the WinGet session itself. It even throws a couple of Ctrl-C (^C) characters to make sure things get closed out. Here’s a screencap:

Disappearing Printer Gets IP-based Fix

Leave a comment

This weekend, we went out looking at new housing developments. To prepare for our quest, I went to print street addresses for model homes in Liberty Hill and Georgetown (two small towns north of here). But when I tried to fire off a print job to the Samsung networked printer next to my desk, Devices and Printers told me it was offline. I’ve learned to recognize it as a sign of driver corruption, so my disappearing printer gets IP-based fix. Let me explain…

Why Say: Disappearing Printer Gets IP-based Fix?

My Samsung ML 2850 is old enough that it does not support the Microsoft Universal Print drivers. I have to load a bespoke device driver to make it work. In turn, that means automated discovery of this network attached printer doesn’t work right, either. That’s why you see the IP address info for the device below in the lead-in graphic (courtesy of Advanced IP Scanner). I use the Add a Printer option that depends on its IP address instead.

The drill is familiar and runs something like this:

1. Notice the Printer is offline
2. Basic troubleshooting doesn’t help
3. Right click the icon in Devices and printers, select delete
4. Use the Add a printer dialog to start the process going
5. Click the “Printer I want isn’t found” option
6. Click the use IP address or hostname on the next pane
7. Use the printer’s IP address to install the current driver

This actually takes longer to explain than it does to execute. But it does work, and it seems I have to do this once every three months or so. I guess that’s the outcome of using a 10-year-old printer (that still works like a champ, BTW). Windows has left it behind, but it still keeps chugging along. Kind of like your humble author, I guess…

Windows 11 Proves More Friendly

Just for grins, I tried discovering the Samsung ML 2850 from a Windows 11 host on the same network. At first, it couldn’t see that device, either. But when I clicked the radio button labeled “My printer is a little older. Help me find it.” the Samsung device did turn up. I had to know enough to select the Microsoft PCL6 Class driver (which handles the interface between the Samsung and the Universal Printing stuff). But once I did that, everything worked as it should. Seems like MS has made Windows 11 rather more printer friendly than I expected (and friendlier even, in this case, than Windows 10). A pleasant surprise indeed!
