I need to edit and replace some files that are owned by TrustedInstaller. At one time you could take ownership of the file (Properties/Security/Advanced/Owner/Edit) but this no longer works in Windows 7. Looks like the security has been increased recently. Does anyone know of a way around this problem now? I need to edit the TS_BrokemShortcuts.ps1 file to keep a machine from deleting the desktop icons. Thanks for any help.
