Is Regcure safe to use on a PC?

We consider RegCure quite safe to use, however we absolutely recommend that you ensure that you have all your important data backed up before you conduct any sort of computer maintenance or upgrade. Storing your files on external media, such as an external hard drive, is the safest way to go. You might also want to consider creating an image of your computer state so that you can return to it should anything go wrong. Useful software is Acronis True Image Home, a program recommended by several high end computer users. This is standard procedure when performing any sort of upgrade, cleaning, or tweaking - no matter what you're doing.

Remember, computers are so complex that there's always the chance that any registry cleaner might remove an important entry. That's why we suggest ensuring you have a backup available.

Well, Microsoft, ... yes, Microsoft tells that it's a high level threat:

Did you see that? It was really Microsoft.com page!

While again look at http://www.regcure.com/
what do you see there? You see Microsoft CERTIFIED Partner! I didn't know that Microsoft has also good relationships with virii makers. Hmm... Sadly, there is no way to check if that logo is for real...
But then again!

What the hell? Microsoft's partner, and a high threat?

Well, then my theory about that Microsoft develops bad Windows versions intensionally, so other software developers could have jobs, is true. Microsoft leaves security holes or other pits of shit, other people research and exploit it and then build a tool for "optimization", "tweaking" or an "anti-viral" tool.... It's all about money making! You scratch my back I scratch yours.

Oh well, so I did a test.
I downloaded and actually installed RegCure on my PC. Yep, PC was still alive after that.
Ran a scan.. it found 111 errors - the actual result, and PC's heart still worked. Btw, I made a note, what errors it found in my registry. Then I opened my lovely CCleaner and ran a scan with its Registry Cleaner - it found 105 errors. Then I compared the results. Both found absolutely the same things, except the 6 ones that CC's RC didn't find were invalid Start Menu shortcuts, which can be erased only using CC's File Cleaner part, since those invalid shortcuts are files that are inside folders, which has nothing to do with registry at all.

So in conclusion, RegCure or not to RegCure?
Well, the only difference between RegCure and CCleaner is that, well, RegCure costs. But sadly, you can do the same cleaning with CCleaner, for free, since CC is freeware. 0.o
Btw, after I uninstalled RegCure, some glitches appeared, like folder, where RegCure was didn't want to close properly, instead, it just faded out.
