After 30 days of Win10, how can I lose back and down?

It’s a month away from the first batch of Windows 10 push (July 29), and Microsoft’s “30 days regret” is about to expire. This means that it is not lost back to the original system. operating system.

This is not a big deal for veterans, but what if you don't like tossing and want to use Win10 again? In fact, the method is very simple.

Win10 comes with a back-off that is based on two folders in the system, Windows.Old and $Windows.~BT (or $Windows.~WS) (windows10 official version of the upgrade file /$ Windows. Where is ~BT?), the latter difference is based on the installation method, this is not important. Microsoft can not retreat after 30 days, it is to delete these two files directly.

So, the response is very simple, first open “ show hidden files & rdquo;, find these two files to rename (they are in the root directory of the system partition), here It’s just fine. Of course, you can also back up to other partitions or mobile hard drives.

As a result, after 30 days, suddenly I don’t like Win10, then change back to the original file name, enter the system and update-restore, and then downgrade the system.

Another method of downgrading: the same operation for rewinding Win7/Win8.1, this article takes the example of rolling back Win7

1, open the settings → update and security → Restore, find & ldquo; fall back to Windows 7 (or Windows 8.1) & rdquo;, click & ldquo; start & rdquo;.

2, select “return” reason (multiple choices), then click “next”continue (every step below can cancel “return” operation).

3, carefully read the precautions, the whole process needs to have stable power support, which means that the notebook and tablet 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 “ Return to Windows7 (or Windows 8.1)”, the system will automatically restart and start the rollback process. This process is time-consuming and directly related to the original system software installation. The rolled-down Win7/Win8.1 system remains active.
