否则,msinstaller, services.msc, regedit

等都会报错:

AppInfo 

svchost.exe 

Facilitates the running of interactive applications
 with additional administrative privileges. 

Users will be unable to launch applications with the
 additional administrative privileges they may require
 to perform desired user tasks.  These tools include regedit.

Although safe to disable, this is not recommended since
 you need to boot into safe mode to enable again.
