Do not let that software anywhere near your pc. When you try to delete it, it bricks your pc. It took me 2 days to get my desktop back up and running.
I still like the free software they have...duplicate file finder, disk defrag and registry repair. Those are good, safe to use programs.
Speedboost said it would make a restore point at install, it didn't. It deleted all my restore points and left me with only the restore point from when I got my pc...2 1/2 years ago.
It was corrupted and somehow turned my pc into a brick. I'm currently running a version of Windows that isn't 'genuine' because I couldn't find the damn box the disc came in to get the key.
So I ordered a new disc from Amazon because Microcrap (damn, I just flamed Microsoft...will Duke report me?) doesn't support 7 now.
edit: and I couldn't just buy a new key from Microsoft online.
