QUESTION
William R. from Fort Walton Beach, Florida writes:
I’m not an aluminum foil hat kinda guy but . . . I’m noticing that my system reboots all on its own now and then, surely a Windows 11 update sort of thing. That said, is there a way to see any boot logs so I can confirm my suspicion? When I worked for a major aerospace company here locally, each time we logged on to our machines, such a log existed, a network thing, I’m sure. I’m not on any network, just my local machine connected to Al Gore’s amazing Internet . . . Thanks Geek.
ANSWER
Jeff Werner responds:
No aluminum foil hat required, William! Your computer rebooting out of nowhere is a classic Windows frustration, and your suspicion about Windows Update is probably spot-on. Windows 11 loves to keep itself fresh, sometimes choosing the most inconvenient moments to pull the plug and restart. In a future issue, I’ll cover how you can take control of these seemingly random reboots.
When you worked at that local aerospace company, your work PC was professionally administered, and the IT department likely used centralized servers to push out updates and manage things with complex login scripts, ultimately creating those network boot logs you remember.
While your standalone local machine isn’t connected to a corporate domain, there is a surprising amount of detail that Windows 11 puts into logs, even on privately-owned and managed machines. There are two diagnostic tools built right in to Windows that can track down these hidden records.
First is the Windows Event Viewer. Windows records every single major event, error, and system state change that takes place on your computer, and this tool is what lets you examine them. To get started, right-click the Windows Start button and select “Event Viewer” or type “eventvwr.msc” into the Windows Search Bar and hit “Enter”.

In the window that opens you’ll find a navigation bar on the left, and within that, you’ll find “Windows Logs”. Drill down into it, and among the log types shown there you’ll find “System”. Click it, and the center pane will populate with thousands of events. Don’t let that intimidate you.
On the right-hand side menu, you’ll find the “Actions” panel. Click on “Filter Current Log…” and then the field labeled “<All Event IDs>”. Remove what’s there and we’ll replace it with the specific Event IDs that Windows uses to track power cycles.
Enter them exactly like this, including the commas between the numbers: “41, 1074, 6005, 6006, 6008” then click “OK” to process the filter.
If you double-click on any of these messages, you will get detailed information about it. Without going too deep into what all these mean (this is only an 800-word column after all) the most important ones to note are 1074, which indicates a clean, controlled shutdown or reboot, and 41 and 6008, which indicate unclean or unexpected shutdowns (for instance, if the power is disconnected).
If you see these frequently, it could be a sign your hardware is overheating, or your power supply is failing.

If navigating the raw database of the Event Viewer feels a bit too tedious, Windows 11 features a much more user-friendly, visual timeline called the Reliability Monitor. This tool translates those raw, technical Event IDs into an easy-to-read graphical interface.
To use it, enter “Reliability” into the search box next to the Windows Start menu. Select “View reliability history” from the search results. You will be greeted by a line graph showing your system’s stability index over the past several weeks. Look for days marked with an Information icon (blue “i”) or a Critical Error icon (red “X”). Click on the specific day your computer rebooted.
The lower half of the screen will show you an itemized list of what happened. If Windows Update successfully installed software and initiated a reboot, it will be clearly listed there with the exact timestamp. Hopefully this will set your troubled mind at ease as to what’s causing your phantom reboots.

Geek Note – Electronics Prices:
If a new computer, smartphone, or tablet is in your future plans, you may want to consider accelerating your purchase timeline a bit. Prices are poised to take a significant jump this summer for a number of reasons, including the rising costs of chip manufacturing, transportation costs, and the unpredictable tariff policies that apply to so many consumer products.
Under ordinary circumstances, I would advise waiting for the back-to-school or Black Friday sales to get the best deals, but our current circumstances are anything but ordinary. Depending on what prices do over the next few months, you could find that waiting results in a discounted price that is still higher than one you could get right now. Shop wisely, dear Geeks! There are still good deals to be had for bargain hunters.
