I have C Cleaner and Tuneup Utilities 2006. While both of them are good, there are some files (Active X, dll, etc.) that are left over from deleted apps that are still in my system. I discovered some of them by accident in C: Windows/downloaded program files.
Are there any good and safe programs out there, free or not, that can do a more thorough job of cleanihng? Something I can use to supplement my current software?
Those can be manually removed by right clicking them and selecting Remove, you'll of course have to run a registry cleaner after removing them such as CCleaner's Issues scanner. If you've ever used a free online virus scanner service they usually place their files in there and leave it up to the user to find and delete them if they never use the free service again.
Those that you can leave in there that are useful for Windows are:
* Java Runtime Environment
* MUWebControl Class - (required to use Microsoft Update website)
* Shockwave Flash Object
* Windows Genuine Advantage Validation Tool - (required to download software and updates from Microsoft)
