I never have such a problem, because I clean my computer a lot.
- First, if you say your problem if definitelay computer space, then give it some space (my C: drive always have 30% of space minimum! and my other always 10 or 15% too) copying your files on another hard drive.
- If you can't, just buy a 1To hd and problem solved
- then, I recommand you my war tools : Auslogics Disk Defrag (or Defraggler if the last version bugs like it bugs on me, but this defragger is almost perfect and fast), Auslogics Registry Cleaner, Auslogics Registry Defrag, Auslogics Duplicate File Finder, CCleaner (use also the registry cleaner functionality), Comodo Internet Security or any antivirus/firewall that works well, Malwarebyte's Anti-Malware, and have Recuva too because it can save your life and it's free.
- With that, you can defrag everyday your drives, it doesn't last more than a few minutes, at least on my XP it's that case. And quite often clean your registry with both Auslogics registry cleaner and CCleaner. And some time to time, virusscan and malwaresbyte your hd.
- now you won't have any problem
