I had hoped for a more concrete and detailed reply telling which folders and files can safely be taken ownership of and which not.
In my Win7, the following are not accessible (and myaby just a few more I missed in a short searched):
2a181ba621897bc56ee637 with subfolders amd64 and i386, the latter are “no permission”
Documents and Settings
Possibly Admin subfolder under PerfLogs (now empty)
Under Program Data: Application Data, Desktop, Documents, Favorites, Start Menu, Templates
System Volume Information
Users > Administrator: Application Data, Cookies, Local Settings, My Documents, Net Hood, Print Hood, Recent, Send To, Start Menu, Templates
All Users > Application Data, Desktop, Favorites, Start Menu, Templates
Default > Application Data, Cookies, Documents: All subfolders, Local Settings, My Documents, Net Hood, Print Hood, Recent, Send To, Start Menu, Templates
Default User
[My Name] > Application Data, Cookies, Local Settings, My Documents (another My Documents is accessible), Net Hood, Print Hood, Recent, Send To, Start Menu, Templates
UpdatusUser > Application Data, Cookies, Local Settings, My Documents, Net Hood, Print Hood, Recent, Send To, Start Menu, Templates
Does anyone have experiences with TakeOwnershipEx-1.1.0.0., Add-Take-Ownership-Option, Take_Ownership and takeownership. Some of these can also remove taking ownership -hopefully without problems.
