Let's deal with Windows old folder on your computer

Here you will find out:

  • what is Windows.old folder
  • methods to erase prior Windows files
  • how DiskInternals software can help you

Are you ready? Let's read!

Windows.old folder — what is that?

If you see a Windows.old folder, you may not know why it is needed and what can be done with it. In fact, this folder is very useful and is automatically created when OS is updated. The Windows.old folder has the configurations and settings of your previous OS version and, if you are not comfortable with the current Windows release, there is a chance to bring back prior operating system condition.

Windows old is a folder on C drive which contains configurations and settings of your previous OS version.

But, since this folder is quite voluminous, it cannot be stored on a computer for a long time, or computer performance will decrease. Therefore, you have 30 days to understand and decide whether you need an old OS since it is after this period of time that the Windows.old folder will also be automatically deleted.

Here are two brilliant short methods to help you. Each of them is simple and easy to apply. All you need to do is to read the article and follow the algorithm. It would not take more than 15 minutes of your time!

Why you may want to remove the Windows prior folder?

Mostly, if you need to find a few more GB to install new software or to launch an existing one.

Another common situation is when the laptop/PC starts to hang up (that may help too).

Method 1. Let your Disk Cleanup utility run

If your PC/laptop works slowly and freezes up, this way is a perfect reason for deleting old Windows files.

In the Search Windows bar type "Disk Cleanup". Open it.

Open Windows search bar and enter Disk Cleanup.

Then click on the Clear System Files tab. Select the Previous Windows installations, and then press OK or Enter. Restart the computer after this operation and that’s it!

Disk Cleanup - select Previous Windows installations.

If this method did not suit, try the second one.

Method 2. Change temporary file settings

This is also a simple and easy way to use.

Go to Start and select Computer Settings. Then select: System -> Storage -> Free up space now -> Remove files. Thus, only will Windows.old folder will be erased.

Method 3. Time will make it instead of you

As it was said above, these files will not be stored for more than a month. So, if you need extra space on your disk C but afraid or lazy to apply any of these methods, you can just wait. In this case, "do nothing" is also a solution.
