When I try to shut down windows of my netbook, it just try to install updates which stops me from closing it and put it into my bag. Therefore I did some googling and found the solution.
- Start gpedit.msc (with run…)
- Navigate to Local Computer Policy > Computer Configuration > Administrative Templates > Windows Component > Windows Update
- Change the setting of “Do not display ‘Install Updates and Shut Down’ option in Shut Down Windows dialog box” to “Enabled”
- Done!
