registry cleaning safe?

[Vyom]

Even I can live w/o cleaning my living room for months. But a little cleaning helps in keeping the room organized, for me and for other guests who sometimes come to visit me
Hoping that someone got the point.

I m planning to clean my registry in an attempt slightly boost the speed of pc. I have never done this before.
Any precautionary advice, suggestions?
OS: Win 7 x64

the registry grows in size as u work on PC daily...

so to optimize it apps are required...

just use CCleaner + Tune Up 2011 and you will never face any issue of reg crash
