for the last 10 minutes or so my hard disk light is constantly on, but i am not really doing anything here that would require heavy disk access. After a bit of digging i could only find the "System" process doing a lot of reads and writes to "c:\System Volume Information\". From what i have just read, this is for system restore points and the indexing service, which i both turned off. Can anyone enlighten me what this does, or how to find out what windows feature exactly is doing this, and how i can windows stop from doing it? (edit: It stopped ... for now.)

a little background info: This is a thinkpad T410 with 4GB ram and Win7 Pro (64Bit). I already disabled all the services i never need (printing, indexing, media center sharing, frikking "Windows is looking for a solution" thingy and whathaveyou). Windows and all the software i use is up to date with the latest patches. Im also quite sure it's not some virus or malware since i don't download any torrents or pirated software, and i know a dodgy site when i see one.

Ok, so after a look at the timestamps of the system restore points (ccleaner->tools) it looks like windows decided to spontaneously create a new restore point just now... ಠ_ಠ

I usually disable restore points (at all, they are useless for many reasons), planned defrag, planned antivirus scan, file indexing (I never search): my system is faster and my hard disks last longer. I also recommend to set Windows Update to just warn you. If you have an SSD disk, also disable browser's DISK cache -- Just my 2c EDIT: sorry, I've just read the 2nd part of your question -- you already done many of these things –  gd1 Aug 13 '11 at 8:53

Yeah, i did that for the exact same reason, and in Control Panel\All Control Panel Items\System ->System Protection -> Configure ... the current "Restore settings" is "Turn off system protection" - so wtf? –  iHaveacomputer Aug 13 '11 at 9:07
    
I can't name how many times a restore point saved my bacon in Windows 7. –  Moab Aug 13 '11 at 14:20
    
A restore point may have been created if some third party app decided to run its own auto updater: Adobe, Java, etc., although usually you would have to intervene to give it permission to install via UAC. –  cantfork Aug 13 '11 at 15:54
    
I can't count how many times restore points could have saved the countless users asking questions here. But to each his own. I would ignore the browser disk cache advice though. In theory, that actually SLOWS down you computer, as the browser forces pages out of memory to the paging file. At best, it will give you maybe a couple of months extra on the SSD? –  surfasb Aug 14 '11 at 0:31
