After many users have joined Windows 10, it is inevitable that users will need to downgrade to the original Windows7/Windows 8.1 system for various reasons. According to the general idea, if you want to downgrade to a lower version of the operating system, it is basically a simple and rude formatted reloading method. However, in the Win10 era, since a large number of users were upgraded from Win7/Win8.1, Microsoft provided a more user-friendly downgrade option for this part of the user: the system rolled back.
but note that this & ldquo; regret & rdquo; feature is & ldquo; shelf life & rdquo;: the successful upgrade to Win10 can be used within one month later, without waiting. In other words, if you repent after a month, you can only use the traditional "simply rude" format to reload. In addition, you need to be reminded that if you want to repent after successfully upgrading Win10, Windows.old, which was previously reserved by Win7/Win8.1, must not be deleted. Because this is the root of “repentance medicine”, once you want to fall back to a lower version of Windows within a month, you must first ensure that the original operating system files actually exist. After the folder is deleted, it can only be downgraded to Win10 by formatting and reloading.
If you meet the above two conditions that can downgrade Win10:
1 in a month
2 does not delete the Windows.old folder
then you can bring it back via Win10 Retreat & rdquo; function realization & ldquo; peace downgrade rdquo;.
The specific method is as follows (return Win7/Win8.1 operation is the same, this article takes WinNA as an example):
1, open the settings → update and security & rarr; restore, find & ldquo; fall back to Windows7 ( Or Windows 8.1) & rdquo;, click & ldquo; Start & rdquo;.
2, select “return & rdquo; reason (multiple choices), and then click “ next step & rdquo; continue (every step can cancel any time at any time & nbsp; fall back & rdquo; operation).
3, carefully read the precautions, the whole process needs to have stable power support, which means that notebooks and tablets need to be retracted when the power cord is connected, the battery mode is not allowed; The system also hinted at some of the possible impacts on files and programs. Once you understand and take action, click “Next" to continue.
4. For users who have already set a login password, the password will be restored after the rollback, so you need to know the password to log in normally. After confirming that the message will not affect your use, click “Next” to continue.
5, the final step to confirm, remind Win7/Win8.1 users can upgrade to Win10 at any time. In the future, the free installation of Win10 will no longer be subject to the time limit of “released within 1 year of the official version”, and is not subject to the installation method. Pure installation will also be completely free.
6. Click ““ to fall back to Windows7 (or Windows 8.1)”, the system will automatically restart and start the rollback process. This process is time-consuming and has a direct relationship with the original system software installation. The rolled-down Win7/Win8.1 system remains active.
