If you’re thinking about getting a windows registry cleaner application, you only really need to bother with the top registry cleaners. Don’t bother wasting your time with the lesser known ones. You’ll end up throwing your money away and will still end up with a corrupted registry and a slow computer.
The main reason people aim to fix their registry in the first place is to speed up their computers boot up time. You’ll notice that your PC significantly slows down (in boot up time) as time goes on. This isn’t because your hardware is getting older, it’s because your computers registry is getting bigger and bigger and the information needed by your computer is getting harder and harder to find.
Your Windows registry grows at a rapid rate as programs are added and installed and changes are made to your computer. Not only that, when you delete or uninstall apps, they always leave a footprint on your registry and never completely get removed. Doing this several hundred times is going to leave your registry in some kind of state.
If you have noticed your PC slowing down then look into investing in a decent registry cleaner. It might be the best few bucks you ever spend.
