The PresentationHost.exe process runs with a restricted process token. The process gives up membership in the Administrators security group and in the Power Users security group. The applications that run in the Internet zone sandbox do not have to have the full permission to these security groups. Additionally, the process gives up many Microsoft Windows NT security permissions.
This behavior is a defense-in-depth security feature. The effect of this feature resembles how non-elevated processes run on Windows Vista when User Account Control is active.
In some account migration scenarios or operating system upgrade scenarios, subtle corruption of Access Control Lists (ACLs) may occur. This corruption causes a particular user account not to be explicitly given access to certain folders or registry keys that belong to the user profile.
This problem may occur because permission inheritance on the parent object is disabled. This problem only affects the applications that have the group membership disabled. For example, the PresentationHost.exe application has the group membership disabled.
This problem is known to affect the permissions for the following registry keys or folders:
- The Classes registry key
- The IPersistMoniker interface registry keys
- Some folders in the following path:
C:\Documents and Settings\UserName\Local Settings
For example, the Application Data folder and its Deployment subfolder, the Apps folder, and the Temp folder are affected.
