Hello, with the installation of RS3 RTM Enterprise x64 this has started: The process C:\WINDOWS\system32\svchost.exe (PC1) has initiated the restart of computer PC1 on behalf of user NT AUTHORITY\SYSTEM for the following reason: Operating System: Service pack (Planned) Reason Code: 0x80020010 ...even if I have set in Policy Editor: Computer Configuration > Administrative Templates > Windows Components > Windows Update > No auto-restart with logged on users for scheduled automatic updates installations (Enabled) No new update was installed. Can anybody help investigating? 1. How to find, which svchost.exe service does it? 2. How to deny such unwanted behavior?
