TASK SCHEDULER
FileKey1=%systemroot%\Tasks|SchedLgU.txt
The above key is locked by the Task Scheduler service, which is not stoppable. However, the key can be added to the PendingFileRenameOperations registry value found at "HKLM\System\CurrentControlSet\Control\Session Manager".
AVG FREE 8.5
FileKey1=%programdata%\avg8\emc\Log|*.log
FileKey2=%programdata%\avg8\Log|*.log
FileKey3=%programdata%\avg8\Log|*.xml
FileKey4=%programdata%\avg8\scanlogs|*.log
FileKey5=%programdata%\avg8\update\backup|*.*|REMOVESELF
FileKey6=%programdata%\avg8\update\download|*.bin
Most of the "*.log" files mentioned above are locked and require the changing of administrative ownership and access (similar to running TAKEOWN and ICACLS from a command prompt). The files can then be added to the PendingFileRenameOperations registry value mentioned previously.
WINDOWS SIDE BY SIDE
FileKey1=%systemroot%\WinSxS\ManifestCache|*.*
This folder is responsible for the caching of Windows Side By Side Manifests in Vista. It only contains a few files (if that) but at least one of them will be huge in size and the remainder may even be orphaned from previous Windows updates and service pack updates.
The Windows Module Installer (trustedinstaller) service must be initially stopped if it is started. Also, administrative ownership and access are required (similar to AVG Free above) for all files in this folder. The files can then be deleted immediately and the Windows Module Installer service restarted. By and large, deletion of anything in the WinSxS folder should be avoided at all costs, but the said files can be safely deleted and will be recreated by the Windows Module Installer service.
