Post SP1 Cleanup, Part 2

When I started developing problems with a couple of SP1 Vista installs recently—application crashes, system instability, system software components shutting down—I started my troubleshooting by eliminating potential hardware-related causes. Once those were behind me, I encountered some issues with the accretion of application installs and uninstalls over time.

Warning! Volume Shadow Copy Service Sometimes Eats Excess Disk Space

The Windows Volume Shadow Copy Service exists to produce clean snapshots of disk volumes, and to create shadow copies of data or files that are consistent, readable, and associated with some specific timestamp. Microsoft abbreviates this service as VSS, for some odd reason or another omitting the C, as in the command line program that manages its behavior: vssadmin.

Help yourself to cool shortcuts!

If you’ve run Vista for a while, you probably know you can get to many programs by looking them up in Help and Support. This typically produces a list of help pages, among which you can usually find a link to launch the program you want.

System Builder’s Blog for June 24, 2008

From time to time, I want to share experiences building Vista systems with our readers. In the last month, I’ve built (and rebuilt) at least three Vista systems, one an upgrade on my Dell Latitude D620 notebook from Windows XP SP3 to Vista Business SP1, another a brand-new build on a QX9650 quad-core system in a very nice Antec 900 case (they call it a gaming case, but I still like it anyway), and another in imaging (then re-imaging) an HP tx2000z tablet PC.

TJmax: it’s more than just a clothing outlet!

TJ stands for thermal junction, and represents a measure of the temperature of a circuit or electronic package at the point where the part radiates the most heat (usually from the top surface). TJmax stands for the maximum temperature that such an integrated circuit, or more correctly a chip or chipset in its socketable package (a usable electronic part, in other words), can sustain before it fails.
