arent those ATI things drivers? will that screw up my pc if i uninstall thetoshiba stack windows 7m before upgrade? what if i cant get them back?

help!
well the ati control center is just the options of your graphics and the install manager is just a manager,and if something goes wrong then theres drivers on the ati website.
The ATI things can be re-installed and Windows 7 has a bunch of built-in drivers anyway. You can remove all that stuff without worry.
