This is one of the best free registry cleaners I have used over the years. They do ask for a small donation but you do not have to pay to use it. It has a lot of features so look over the options first before you use it. You can also make a backup in case you erase something you did not intend too. Most of the time when your computer slows down it is because of all the junk loaded on it. This program will clean your registry files, cookies and a lot more. You can select which applications to remove also. It will not completely fix every thing but about 99% of it. You will be amazed how fast your computer will be after you run the program. I highly recommend it. CCleaner (dot) com is where you can find the program for down load. I am not affiliated in any way with them. Its just a really good tool. Other program applications charge you big bucks for the same service.
ya i had that when i upgraded to Win 7, CC cleaner is pretty quick compared to the one i was using before
Yea, I also use CCleaner. It can clean up temporary internet files, cookies and history. I is also a registry cleaner. But the best thing about CCleaner is its price == it's FREE!
