Hi,

CCleaner might have created a backup for the registry entries that were removed. Check
with Piriform Support and ask in their forums.

You can try some of these in Safe Mode - repeatedly tap F8 as you boot.

If you do not have a Windows 7 disk you can borrow a friends as they are not copy
protected. Your System maker will also sell the physical DVD cheap since you already
own Windows. Also you can make a repair disk on another computer.

Try Startup Repair - (If at ANY point you gain some but not full access to Windows come
back and try Startup Repair again.)
