Delete Previous version of Window? Windows 10

If you have recently upgraded to Windows 10 and are wondering whether you should delete the previous version of Windows, the answer is not straightforward. There are pros and cons to keeping the old version, and it ultimately depends on your specific situation and preferences.

Here are some factors to consider before deciding whether to delete the previous version of Windows:

Pros of keeping the old version:
– Backup: If you encounter any issues with the new version of Windows, you can always revert back to the old version without losing any data.
– Compatibility: Some older programs or hardware may not be compatible with Windows 10, so keeping the old version can ensure that you can still use them.
– Familiarity: If you are used to the old version of Windows and find it more comfortable to use, you may prefer to keep it.

Cons of keeping the old version:
– Disk space: Keeping the old version of Windows can take up a significant amount of disk space, which can slow down your computer and limit storage capacity.
– Security: Older versions of Windows may not receive security updates, leaving your computer vulnerable to malware and other threats.
– Maintenance: Keeping two versions of Windows can require more maintenance and updates, which can be time-consuming and potentially cause conflicts.

If you have decided to delete the previous version of Windows, here are the steps to do so:

1. Press the Windows key + X and select “Settings.”
2. Click on “System” and then “Storage.”
3. Under “Storage sense,” click on “Change how we free up space automatically.”
4. Scroll down to “Free up space now” and click on it.
5. Check the box next to “Previous Windows installation(s)” and any other files you want to delete.
6. Click on “Clean up system files” and repeat step 5.
7. Click on “OK” and then “Delete Files” to confirm.

It is important to note that once you delete the previous version of Windows, you cannot undo the action. Therefore, make sure you have backed up any important files and programs before proceeding.


In conclusion, whether or not to delete the previous version of Windows ultimately depends on your individual needs and preferences. Consider the pros and cons carefully before making a decision. If you do decide to delete the old version, follow the steps provided and make sure to back up any important files beforehand.
