Estimating Windows 11 Restart Time

Estimating Windows 11 Restart Time

Because today is Patch Tuesday (November 9) I got several opportunities to see WU at work handling updates. Owing to across-the-board Cumulative Updates (CUs) today, that meant 1 production version, 1 Beta version and 2 Dev Channel versions. As you can see from the lead-in graphic, estimating Windows 11 restart time is now part of what WU offers. I thought this was pretty cool, until I realized all 4 PCs proffered the same estimate.

What Does Estimating Windows 11 Restart Time Tell You?

Just for grins, I timed a couple of my restarts to see how long they would actually take. I’m pleased to report that the MS/Win11 estimate is conservative. It took 1:25 to get to the desktop with GadgetPack running to show me a second hand on its clock widget on my X1 Extreme (i7-8850H CPU, 6 Cores). It took 2:35 to get to the same place on my X380 Yoga (i7-8650U CPU, 4 Cores).

That tells me that MS isn’t necessarily driving the estimate from observation of previous start times. Rather, it looks like a rough-and-ready interval that will not set user expectations overly high. Why do I say these things? Because the number was the same across a range of CPUs. And because the number was too high for all of them.

My gut feel is that if this estimate were data driven, it would be slightly high on some and slightly low on others. Because it was the same for all four PCs, and too pessimistic likewise, it strikes me as a “safe estimate” probably based on worst-case observations.

How Does 4 Minutes Strike YOU?

All this said, I think 4 minutes is neither a terrible number nor a glorious one. When I’ve really worked at getting start-up times to their barest minimums on Windows 10 (haven’t yet tried this on 11) I’ve seldom gotten below 1:30 or so. But I’ve read about others who’ve documented start times just under a minute (0:45 or higher).

This may be a fruitful topic for research and play. Now, I just need to find the necessary spare time…
