Before performing the downgrade operation, there are several issues that should be clearly understood. First of all, we only have one month to decide whether to stick with Microsoft's latest system or roll back to the familiar Windows 7 and 8/8.1 systems. Once this period is exceeded, you can only downgrade through your own backup. The most critical point is that so far, Microsoft has only stated that Windows 10 systems can be downgraded to Windows 7 and 8/8.1 systems. It is still unknown whether it can be rolled back to Windows XP systems.

Before officially downgrading, you need to ensure that the files saved in the computer are safe and quickly check whether the system can be rolled back. Just like ordinary system reinstallation, we recommend that Windows 10 users back up important data before downgrading, such as uploading it to cloud servers such as OneDrive. Sensitive private files are best stored in devices such as USB flash drives and mobile hard drives.

In terms of checking whether the system can be downgraded, you can judge by looking for a folder named "Windows.old" in the system disk, because the folder contains the necessary files to downgrade to the previous version. If this file If the folder does not exist, it means that your system cannot be downgraded.

After confirming that the above preparations are completed, the formal downgrade operation will begin. First, you need to select "Update & Security" in the Settings panel of the Start menu.

Click on the "Restore" option on the left side of the window.

Select the "Return to the previous Windows version" option among the multiple recovery options that appear in the window, and click the Start button.

Before starting the downgrade operation, the system will pop up a window to get the reason for rolling back to the previous version. Don't worry, any feedback is acceptable. Then, Windows 10 will also let you choose the file types you want to keep. Finally, the system will give you a final confirmation whether you want to downgrade. At this time, you only need to click Confirm to start the downgrade operation. In addition, the downgrade operation requires us to wait for a while to complete.
