[Solved] High Disk Usage

[Joulle]

This may or may not work but try this:

Go to your run on your computer (Hold windows key and press R) then type 'temp'.
Then what you need to do is delete everything inside that folder, if it says 'cannot be deleted just press skip.
Then go to your run again and type '%temp%' and do the same as above, type 'prefetch' after %temp% and then go to your recycle bin and clear it. This helps me when my hard disk is a little sluggish and you can clear up to 30GB of space in just them three temporary file areas.

Thanks, this worked. However, like other solutions it stopped working after a while so i'd like to keep this open incase the problem comes back. I'll keep it updated. So deleting files can help fix this? (Will deleting like 120gb of video help?)

Yeah, things taking up THAT much would be a good idea to remove

What exactly were you doing at the time you took the screenshot? Did you open or close any programs during the last 5 minutes from the time you took the screenshot? Did you install, edit a simple setting anything during that time? If your pc is idling just at the time and you're playing, say music only that's extremely high usage for just idling. Here's some perspective on when I have 10 tabs, music on, few communication programs running

Spoiler :

No, don't delete static files. That won't solve a thing unless your drive(s) are extremely near to being full (few GBs left). If something as ridiculous as this would slow down your pc, no server or 8TB drive would be in sale.

Cortana itself is known to cause significant performance issues in earlier win 10 builds and in the screenshot I can see cortana hogging 20% of your drive resources, I'd suggest disabling it and see if that solves the issues. There are numerous easy ways to disable cortana, I'd do it via a registry edit (google is full of ways to disable win 10 features, if you run in to a trouble with this, ask).

I did some googling and this could also be caused by cortana cataloguing/indexing your music files for groove music -program.

However, this could also be caused by malwarous files in your temporary folders. Especially since you stated that clearing those files temporarily sped up your system but the problem came back. Maybe a program such as your browser is infected or a site you've visited brings back the malware. I'd do a scan with both malwarebytes and their separate 'adw cleaner' program and run ccleaner on top of that.
