This article mainly introduces how to free disk space after the main update of Windows 10, which is very detailed and has certain reference value. Friends who are interested must finish reading it!

If you want to install the latest half-yearly update to Win10 (spring update or fall update), check the available hard disk space before and after the update. After the update, you may notice that your free disk space is reduced. This is because if you want to restore to a previous version, Windows stores the installation files for the previous version. Never mind. At some point, however, you may want to stick with the newer version. Then how do I clean up the old folders that take up disk space? Let's see.

After installing the latest major Win10 update, open File Explorer to the root of the C drive or any system drive with Windows installed. You should find two folders: Windows.old and windows10Upgrade. If you need to return to the Windows.old folder, it will store all files from previous Windows installations. The windows10Upgrade folder is generated by Windows Update Assistant and used to perform the actual update (figure A).

In the list of installed applications, double-click the windows 10 Update Assistant to uninstall it. After removing the program, check the system drive and you will see that the windows10Upgrade folder disappears.

Next, it's time to get rid of the Windows.old folder. In fact, Windows automatically deletes the folder after 10 days, but if you don't want to wait, you can delete it yourself. Go to Settings and select the system category. Click Storage Settings, and then click the link to configure storage awareness or run now. On the next screen, check the Delete previous version of Windows box. Then click the clean now button (figure C).

You may still see the Windows.old folder, although most of its contents will be deleted. To delete it completely, simply right-click the folder and select Delete from the pop-up menu. If this does not work or an error is received, it must be deleted from the command prompt. "in the search field, type cmd." Right-click the match result for cmd and select run as administrator. At the command prompt, type rmdir / s / Q c:\ Windows.old. Check the system drive-the folder should now disappear (figure D).
