What you may not realize is that your old install of Windows 7 or 8 is still hanging around on your hard drive.
These old files usually take up tons of space – as much as 20-30GB! This is especially bad if your main hard drive is an SSD, which usually have more limited storage space.
There is a reason these files are still around: Windows 10 gives you the option (in Settings) to revert back to your previous version of Windows within 30 days of upgrading to Win 10.
But, you bit the bullet, and you’ve decided to stick with Windows 10.
So, how to get rid of all these useless old files?
It’s really easy.
You may have seen the two primary locations where these old Win 7/8 installation files are located. They are:
There are some files in other places, but the above 2 seem to be the biggies. If you try to delete these folders manually, you will discover that Windows won’t let you.
But, you’re ready to wipe ’em! Here’s how:
First, click the Start button, and type: disk cleanup
Then, launch the Disk Cleanup utility by clicking on it:
On the next screen, you’ll want to scroll down in the list and check the boxes for:
- Previous Windows installation(s)
- Temporary Windows installation files
But you can also select some of the other stuff if you’d like, such as Device driver packages or Thumbnails.
Then, just click OK.
You might see the following prompt… Just click YES!
And then you’ll have a bunch more free hard drive space!
