WinSysClean is a tool that performs various maintenance tasks on your computer, including registry cleaning.

The interface of the program is user-friendly. At a first glance, you can view system information, system restore points you have created, RAM and disk usage, as well as the date and time of incorrect Windows shutdowns.

There are several options you can choose from, including "File and Disk Cleaner", "Windows Options", "Applications" and "Registry".

But other features of the program can be found on the bottom of the window - "Edit Windows Startup", "Defragment Hard Drive", "Memory Diagnostic", "Uninstall Programs", "Repair Internet Explorer Favorites", and more.

So, you can delete custom files (by adding file types), CHK, BAK, GID, TMP files or WinXP Thumbs.db image cache files, as well as clean the Windows documents history, invalid start menu shortcuts, memory dump files, invalid shell extensions icons, error reporting files, and others.

Furthermore, you can get rid of the Microsoft Office recent files history, but also of the Word, Excel, Access, PowerPoint and FrontPage MRU list, the Apple Installer cache, iTunes Album Artwork and GoogleEarth cache, and more.

When it comes to the Windows registry, you can also select what you want to delete - invalid type library entries, application paths, font entries or shared tools entries, obsolete software entries, missing file extension associations etc.

Additionally, you can configure cleaning options for Internet Explorer, Firefox, Opera, Safari or Google Chrome (e.g. delete URL and download history), but also for Yahoo Messenger and Skype (e.g. delete logs).

Plus, you can monitor the CPU, memory and disks, but you can also access "Desktop Tuning", schedule tasks, change folder settings, create and restore a registry backup, and view the last cleaning log.

The program takes up a moderate amount of system resources and doesn't seem to cause any problems. Every time you initialize it, WinSysClean suggests you create a system restore point.

However, WinSysClean incorrectly displayed the RAM of our computers, takes a long time to complete a file cleaning task and its help file has insufficient content. Moreover, the "Defragment Hard Drive" and "Memory Diagnostic options you access from here actually belong to Windows.

It takes several seconds for the tool to comply when you're aborting a task, but you can view the total disk space recovered, registry entries scanned, fixed registry errors, scanned and removed files.

All in all, WinSysClean provides a good solution for cleaning up your computer, but it definitely needs some debugging and upgrades.
