ScanSys - Version 1.01.0114 Scans your computer's system folders for any changes that may have been made due to installations etc. ScanSys will notify you of any system files that have been updated, downgraded, added, or deleted. If a file is found to be downgraded or deleted, ScanSys will allow you the option of restoring the file from a backup or installation disk. ScanSys can also be used as an installation monitor, allowing you to log all your installations, so you can see at a glance where all these .dll's and .vxd's came from.
