Our recommendation: don't fix what ain't broken, so don't update your drivers, unless it's really necessary because they don't function any more. And in that case, download it yourself from the makers site in stead of relying on a program to do that for you. So no app at all.
You might like to use other programs for other things than drivers, but since you don't tell your specific requirements, it's difficult to give any other advice than "Don't buy a registry cleaner" or, even better, "Don't use a registry cleaner."
Can somebody please give me some suggestions, about what is the best driver update app. It seems i have to get a few apps to get everything done. I want to get a app that will update my drivers, repair, and just keep my pc running in top form, all with one app, not a couple.
