Registry key location for software deployed via Group Policy?

Look in:

HKLM\Software\Microsoft\Windows\Current Version\Group Policy\AppMgmt. Find the key that corresponds to the software you're looking for, and delete it. Then run gpupdate /force and restart.


I believe:

GPO applied to the local computer:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Group Policy\History

GPO applied to the currently logged on user:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
  \Group Policy\History
