Some users seem to have problems restoring deleted and backed up files (e.g. History items) in PowerTools Lite.
In this post I already gave the answer:
redseujac wrote4) You can always use the backups to undo deletions. Just click on "Undo". Then right click the backup file(s) and choose "Custom restore/Edit backup". There you can find the deleted files and restore them.
Of course you are also able to select and restore the individual files of your choice.
Naturally the user can just restore everything (i.e. all found and deleted items [registry entries ), simply by clicking Undo, selecting the backup and clicking Restore.
