Vista Optimizer slimmed down the system, didn't care, and deleted everything that shouldn't be deleted.

I don't know if you have any problems now, but I think so. Cleaning tools will not invade your system. .......

It is intelligent and only kills those junk files. ....

Don't worry if it doesn't affect your current operation!

As for the question that you want to use XP, I personally think that XP is not as comfortable and safe as Vista, and now I can't stand XP!

Of course, your laptop XP can be installed, and vista can be installed, not to mention low-level XP!

Personally, I still suggest vista. .....

Ha ha! Be careful when operating those tools in the future. .....
