100% Disk Usage in Windows? Here's How to Fix It!

Prefer to read this instead?

Your computer is hanging. Same old Windows, right? Except you’re using a brand new Windows 8.x or Windows 10 device; you’ve only had it a few days. So just what is going on?

Investigating, you discover that your system drive is running at 100%. Surely this can’t be right? Sadly, it is. The latest versions of Windows have a problem with the drives being over worked, which slows down the operating system. This issue affects both hard disk drives (HDDs) and solid state drives (SSDs).

Several fixes are available for this, depending upon what exactly is causing the problem.

  37. I'm Using Windows 8.1 and it's Hanging like this

  38. Honestly, Windows 10 is worse than Vista, and Vista was verifiably a deliberately released piece of software that was designed to be slow and buggy – there were leaks of microsoft staff suggesting that its a good idea to release an incomplete and unstable OS to the public. I honestly think the same happened again with windows 10.

  39. THanks literally had my pc for two days and I had too do this hahah
