100% disk usage?

Go and use win7

I solved this problem by installing win7 instead.

I have been having this issue too, i will post here if i find a solution.

It was the reason I downgraded to Win 7
I did like you did and looked all over the place for it. I never found an answer.

Unless you like having legos on your desktop, switch to Windows 7

I used to have this problem with Win 7. With Win 8 it stopped. Maybe it is because of the fresh install.

Changing to Win 7 isn't a solution. Win 7 is really a downgrade.

Huh, did you check your CPU usage?
Ctrl+Alt+Delete, Start task manager, click the Processes tab, click CPU to list based on CPU usage. Check to see if anything is using 95%-100%.
I used to have an issue with a windows program that would suddenly reach 96% CPU usage... Can't remember how I fixed it, though.

Maybe clear the cache by using Ccleaner as the amount of temporary files may have increased or maybe format the system.You can also do disk fragmentation and see if something is wrong with that part.Mostly it should be the fault of any software.

I'm on windows 8.1 and i has this same issue, i though was my hd old... but alot ppl has this problem...

i think was last updates, fucking windows 8

I read "100% dick usage" :p

You should be reported for such a misleading title. I'm dissapointed after checking the thread out. :p

Normally disk usage is related to ram, once your pc runs out of ram it creates a page file, and windows will constantly be reading your hard drive to access that page file. With 16gb of ram installed make sure its at least being recognized by windows, just right click "Computer" from your start button and choose properties, ensure it says 16GB installed. If that's the case try this program, http://crystalmark.info/software/CrystalDiskInfo/index-e.html this will monitor your hard drive. If its not an SSD then you may have a wonky hard drive. My final solution would be a fresh install of windows 8 to see if its a software issue after you try those previous options.

Sounds like search indexing, but could be just about anything that constantly uses the hard drive like anitvirus. Disable services and programs that start up and see if it has any effect.

i'll just take the high road, going back all the way to xp!

Stop Superfetch Service.........

How much RAM do you have ?

I personally disabled the superfetch service because that was loading too much stuff in my RAM whenever I closed almost anything that uses alot of RAM (hence removing the cache held by prefetch and was required to re-load it, therefore 100% disk usage for a while), which is even the browser... but I have only 2GB.

For 4GB or more you shouldn't disable that because you'll notice that programs start slower... unless you open and close high RAM using programs that force the cache to be unloaded and then re-loaded from HDD.

You can use resource monitor (resmon.exe) to see what process is using 100% disk usage

acquire ssd

Use google they should say. Google has these sorts of answers they say. Don't ask random people on forums they say. But yet here we are. Since I have nothing productive besides that, I will make the halfhearted answer that if you delete system 32 you will not have to worry about disk usage. Will it create an even bigger problem? Sure. Will it solve the current problem? Kinda.

same here

i also had 100% disk usage on windows 8.1 64bit, on idle (and no, there wasnt anything running on background like antivirus scan or anything else), and i remember i was also searching on google about it
next day, my HDD died, it couldnt boot windows anymore
but i had warranty on it, so they gave me new HDD in 1 week and it came with windows 7 professional installed, so i kept win 7

Go for windows 8.1 enterprise with all the updates from windows

Had this problem too, tried everything, that was suggested. It worked, for a while, but the problem comes back eventually. So far, the only working solution is going back to Windows 7.

Personally, I would install Advanced System Care. It will clear and fix tons of stuff on your windows. Might solve your issue.
