Whatever you do, don't use CleanMyPC Registry Cleaner to defrag the registry - it is a good registry cleaner but it ruins the registry if you use defrag on W7. I did this 2 days ago and it said it saved 56% space which I thought was alot & it turns out it was - after I rebooted it would not start up, it just keeps looping back to the start, shows the starting screen then a blue screen quickly flashes & after 2 loops it goes to the internal repair system which fails to fix the problem.
I was lucky to use the inbuilt backup utility that Win7 has - I advise to use this and schedule it. As most distributers do not ship with the Win7 disc I thought my 3mth old laptop was screwed, but luckily Win7 Repair Disc x64 is a great utility you can download which searched my HD for a backup image then reinstalled it which took about 3hrs but was only 1 day old so I was lucky not to loose anything important.

So remember to look after your system and use the inbuilt back utility. I also use the following-:
* TuneUp Util. 2010 (for optimizing, quick defrags etc)
* Advanced Defrag 4.2 (advanced defrag monthly)
* ThreatFire (picks up any threatening behavior or programs acting strange or altering which is great for malware detection - works with any AV too).
* CCleaner (for cleaning temp files and history)

Good Luck.
