Geek Note: Continuing last week’s theme of “Unfinished Business,” I have the following supplement to offer. In Issue #983, May 24, 2026, reader William R. was asking why his system rebooted, seemingly randomly, and I showed him how to use Windows Event Viewer to view the logs that Windows maintains about such events. I concentrated on that, knowing there was far more wisdom to impart. I said in the column, “In a future issue, I’ll cover how you can take control of these seemingly random reboots.” Well, the future has arrived, so here we go.
The most important thing to know in situations like this is that Windows does not reboot “randomly”. When Windows goes to all the trouble of restarting, there is always a reason for it, whether it is because of a hardware fault (which could be anything from bad RAM, to a failing hard drive, to an overheating problem), misbehaving software/malware, or the most common, because a system update has occurred that involves files that cannot be updated while they are in-use.
Hopefully, after my reply in Issue #983, you have the answer to “why” any given reboot happens. Now, if you choose to do so, it’s time to tell Windows not to reboot on its own.
Being in control of reboots means you don’t have to worry about applications you left open being terminated in the middle of the night just because it’s convenient for Windows. It’s so easy to lose hours of work on your latest video editing project, or sorting pictures, or writing the great American novel, if you – like me – tend to just stand up and walk away from your computer.

If you forget to save your files, you can wind up having to redo a lot of work. I don’t know about you, but my time is more valuable to me than that.
You can easily alter Windows’ behavior so it stops disrupting your workflow. One kneejerk reaction is to simply turn off automatic system updates and resort to doing them manually. You need not block updates entirely; you just need to set some boundaries.
First, you want to configure Active Hours to tell Windows when it can expect you to be using the system. Go to “Settings,” then “Windows Update,” and select “Advanced Options”. Locate “Active hours” and adjust the timeframe to match when you typically use your PC, or when you don’t want the system to “randomly” reboot. Once set, Windows will completely avoid automatic update reboots during these specified hours.
If you are working on a critical project and cannot risk files being lost from an unexpected interruption, you can pause updates altogether. No updates – no reboots. From the main Windows Update screen, locate “Pause updates” along with a drop-down that specifies a duration. You can select from 1- to 5-weeks. That’s long enough to get you past any “Patch Tuesday” updates that Microsoft might push out.

So far, the solutions I’ve offered are for normal, operational reboots that are required for installing patches and updates. If your system is rebooting because of any of the system failures I mentioned above, you must know that nothing you can configure in Windows is going to stop those from happening.
You must address the root cause of the failure in order to fix it. Whether that means blowing the dust out of the chassis to prevent overheating, or getting rid of malware, or replacing just plain old hardware, the solution is there – you just need to identify it and take action.
This is Issue #991 of It’s Geek to Me. If you’ve been paying attention, you know that I plan to get the column to at least 1000 issues, but after that, I don’t know what will happen. Without your participation in the form of reader submissions, it’s gotten more and more difficult to generate content each week. If you have a question, now is the time to ask it, before the column goes the way that so many other great, free, online services have gone before it and goes sailing off into the sunset.
