[wkdsean88]

Hi i have been having an issue where windows will restart the PC at 8.36am every day, doesn't matter what program is running. I have no scheduled events.

if i go to event viewer i get the following

The process C:\WINDOWS\system32\shutdown.EXE (DESKTOP-UV8LQ0T) has initiated the restart of computer DESKTOP-UV8LQ0T on behalf of user DESKTOP-UV8LQ0T\Sean for the following reason: No title for this reason could be found
Reason Code: 0x800000ff

any ideas?

Export your System and Application logs and upload them as follows...

1. Enter the command eventvwr into the Run command box. The Event Viewer will open.
2. Locate the Windows Logs folder in the left hand pane and expand it by clicking on the arrow (>) to the left of it.
3. Right-click on the Application entry and select 'Save all events as...'. Choose a folder anywhere that suits you and a filename of 'Application' (an .evtx suffix will be added automatically).
4. Right-click on the System entry and select 'Save all events as...'. Choose a folder anywhere that suits you and a filename of 'System' (an .evtx suffix will be added automatically).
5. Zip the Application.evtx and System.evtx files together and upload the zip file here.

Zip the Application.evtx and System.evtx files together and upload the zip file here.

Don't know where you copied these instructions from, but you can't "upload" the zipfile here.

I didn't copy them, I wrote them, but fair enough. Upload the zip file to the cloud then, with a link to it here. Be sure to make it public.

I don't know about you, but I certainly wouldn't download a random zipfile.

Linking it here directly would likely get deleted.

I'll stop trying to help then.

This: "Hi i have been having an issue where windows will restart the PC at 8.36am every day, doesn't matter what program is running. I have no scheduled events." (My underline.)

Does that mean that you looked in Task Scheduler?

It could very well be that you did not create that 8:36 a.m. scheduled event but it could be that some app may have done so.

Event Viewer can be very helpful. There is also Reliability History/Monitor - much more user friendly and the timeline format can reveal patterns.

Also take a look at what all is running on your computer via Process Explorer (Microsoft, free).

What you are looking for is some unknown or unexpected process running in the background - could be a potential culprit.

No need to take any immediate actions.

Objective first being to discover the cause of the restarts.

Then work on finding a fix.

A fix that does not immediately involve registry edits or downloading risky .zip files (or any type of file for that matter) from sketchy sources.
