These tools are never any good, yet they continuously keep roping people into using them. Took me a long time to realize this but when I stopped using junk like this I stopped having pc problems, freezes and crashes I also had stopped having to do system restores , resets and reinstalling my OS.
I can't remember the last time I had to reinstall or reset my OS, except for Windows Upgrades. Any tool you need to fix, repair or clean Windows is included with Windows, no need for anything else.
The ONLY utility I keep on my system is CCleaner, that's it. I just use the cleaner part of it, not even the registry cleaner, keep warez and questionable software off my system and do not surf where I do not belong and my pc runs just as quick as the first day I bought it ...... and it's 5 years old. The only reinstalls I have done is when I upgraded from 7, then to 8 / 8.1 and now 10.
