How to Delete Previous Version of Windows on Windows 10

After I upgraded my Asus X205TA to Windows 10, I found that I only have a few MB left on the system drive. I had to delete the temporary previous version of Windows to save disk space. The system even reminds you to do so. If you did not see the prompt, follow these instructions:

  1. Click on the Windows button
  2. Type storage
  3. Click on Storage
  4. Click on This PC (C:)
  5. Scroll down and click on Temporary Files
  6. Scroll down and click on Delete previous versions
  7. Click on Delete

If the Storage settings does not appear in the search results. You can click on Windows button and click on Settings. Type storage in the Find a setting box on the top right corner.  After the Storage settings is found, just follow the steps 3 to 7 to delete the previous version of Windows.
