降级Windows 10到Windows 7或8(超过30天后)

There are four methods available. Choose the one that best suits your needs.

Method 1: Roll Back to Windows 7/8 within 31 Days

It’s true that if you upgrade to Windows 10 sometime within the first month, you can still downgrade back to Windows 7 or 8.1 directly. This is your one and only chance.

Navigate to "Settings" > Tap on "Update and security" > Click on "Recovery" > Tap on "Get Started" under "Go Back to Windows 8.1" or "Go Back to Windows 7."

Then all you need to do is wait patiently and welcome your old Windows 7 or 8 back to your PC.

Method 2: Rename the folder within 30 days and effortlessly revert to the previous system after 30 days.

This method involves changing certain folder names within 30 days of updating to Windows 10. After this 30-day period, you can freely revert to your previous system, such as Windows 7 or Windows 8, without any limitations.

Solution 1. Rename the folders: $Windows.~BT, $Windows.~WS, and Windows.old to Bak-$Windows.~BT, Bak-$Windows.~WS, and Bak-Windows.old, respectively.

Then Windows 10 will fail to delete Windows.old folder with these renamed folders.

If you need to roll back after 30 days, you can rename these folders back to their original names and follow the steps below:

Solution 2. Go to "Settings" > "Update & security" > "Recovery" > "Go back to Windows 8.1 or Windows 7".

You can also back up these three folders to an external drive with their original names. When you need to downgrade the system, copy these three folders back and then follow Step 2 to proceed with the downgrade.

Method 3: Uninstall Windows 10 after 30 days to revert back to Windows 7/8

This method is suitable for Windows 10 users who have only upgraded once, from Windows 7 or Windows 8 to Windows 10. If you have updated Windows 10 multiple times, this approach might not be effective. However, if you have only performed a single upgrade, you can uninstall and delete Windows 10 to revert back to Windows 7 or 8 within 30 days.

Navigate to "Settings" > "Update & Security" > "Recovery" > "Get Started" > Select "Restore factory settings."

The "Restore factory settings" option will remove your personal files, apps, and settings, and even reinstall the version of Windows that came with this PC.

Method 4: Perform a clean install to roll back to Windows 7 or 8

If you have updated Windows 10 for many times or failed to roll back to Windows 7 or 8 by following the above recommended methods, your best bet would be to perform a clean installation of Windows 7 or Windows 8.

You can go directly to the Microsoft Windows page to download the relevant Windows 7 or Windows 8 ISO files or installation patches, and then perform a clean install on your computer.
