Screwing up my computer

I did the unthinkable and cleaned my registry of Windows Vista Home Premium O.S. There was a lot of conflicts in the system and what did I do? I saved the files that were in conflict on my hard drive and then pressed the clean button. And after that I did defrag with a free software called defragger which I had downloaded. It freed up a lot of space and maybe screwed the system up in the process which was already screwed earlier by CCleaner.

The following morning when I wanted to play my audio CD, the system couldn't read it. Hey what did I do? I screwed up my system and I also lost my auto play on the process and God know's what else I have deleted. My word of advice is "DON'T MESS AROUND WITH THE REGISTRY" and what I did was I reinstalled back the registry files that I had in my hard drive and the computer can read my Audio CD but my auto play is still out.

When I tried to do a system restore, I had problem as the last restore point was after the deletion. Now I guess I have to reset my system back to company settings or as when I purchased it. The problem is that I am in Hyderabad and I left my external hard drive at home in Kuala Lumpur.

Not that the system is not working per se, but I somehow have this urge to put back all the drives or other stuff that I have deleted. Isn't there anyway that I can do that without losing all my data? Let me know, please.

I spend the whole of last evening until midnight trying to search on-line for help but it was of no avail. I will be going back home by the end of this month and then maybe I can back up all my stuff and use the recovery disc which I had created after running my system for the first time to reinstall my windows vista.

I hope I don't do any crazy stuff until then and be satisfied with the damage that I have caused. So my advice to you again is, if you are using CCleaner, be very careful and don't touch that registry unless you are an IT geek.
