Sometimes, your PC can run slowly even if you only have a few programs running. And when you check the Task Manager to find out what’s wrong, it might show you disk usage at 100%. Fortunately, this is not the hardest issue to fix. Check out some solutions below:

Opening the Resource Monitor

The first thing to do according to a Redditor is:

opening the Resource Monitor and using the Disk tab to find where the operations are happening and which processes are performing them.

Disabling Windows Search

  1. Type cmd.exe in the search box, click Command Prompt, and then choose Run as administrator.
  2. In the UAC window prompt, click Yes.
  3. You can also go to the Command Prompt window, type “net.exe stop “Windows search””, and hit Enter.

Virus Check

You should disable this and keep your system updated. The only way your PC could become infected is to run an infected file.

Chrome and Skype

These two cannot cause lockups. Corrupted memory, bad drivers or overheating hardware can be to blame.

Superfetch and Windows Search

These help your machine start faster and search faster. If you don’t mess with them, they’ll work just fine.

Resetting virtual memory

Virtual memory is an extension of your PC’s physical memory through a combination of RAM and a portion of the hard drive. When RAM is not enough, Windows will use virtual memory for temporary file storage and will swap back when needed.

  1. Go to Start > File Explorer.
  2. Right-click This PC > select Properties.
  3. Click Advanced System Settings > click the Settings button.
  4. Go to the Advanced tab > choose Change in the Virtual Memory category.
  5. Make sure the box before “Automatically manage paging file size for all drives” is off.
  6. Select the windows drive, set the number as you wish, then press Set and OK.
  7. Clear all files.

Another option is disabling the Antivirus Software and Windows Defender.
