As many people will be aware, Driver Sweeper is a piece of software that cleans the registry of old drivers etc.
Anyway their was a bug on the old versions of Driver Sweeper Version 2.8.5 - 22-01-11 and prior releases in which if your using AMD/ATI Graphics cards it would remove windows (ATI/AMD) system drivers required if you updated to Windows Service Pack 1 which has been fixed in versions 2.9.0 and newer - SP1 checks to see if all system drivers are there, if they are not it won't install.
If anyone does a search for Driver Sweeper you will notice it brings up the Guru3D website, the problem is they list version 2.1.0 which dates back to 2009 and they have never updated the website regardless of numerous people on the Guru3D forums notifying Guru3D about the updates - they simply delete the posts.
It's as if Hilbert Hagedoorn (Owner of Guru3D) is reluctant to make software updates on their website, when the developer requested Hilbert to remove the Driver Sweeper software from the Guru3D website he was banned from the forums, all e-mails whether from the developer or people using the forums to request the update to the latest version were deleted off the Guru3D forums.
So there you go, a big thumbs down to Guru3D website
people oblivious to this will be just downloading the old software from your website.
