It can get pretty annoying if your computer restarts everyday without an option to postpone or cancel it. My desktop PC (Windows 7) was restarting itself between 4pm – 5pm every day. Here is how I fixed it.
The root cause -probably- is one or more updates that are stuck in the process. They force your PC to be restarted by assuming that all updates are completed but they actually never are.
If this issue occurs in your work computer, make sure to contact IT department first. If nothing works and if you have administrator rights in Windows, try the steps below.
- Login Windows with the administrator account
- Go to Add/Remove Programs
- Repair the applications that may be trying to update. It was SEP (Symantec Endpoint Protection) in my case
