**** Ngo here, and so is Windows 10.
Now you might have just installed it, but I've been using for weeks now.
That's not the point.
The point is, what if you change your mind and wanna go back to previous Windows.
Maybe you miss the Lovely tile styled manual Window 8.
Maybe you want to use Window Media Center, or maybe you just stubborn.
For whatever reason, here's how it can quickly rollback to the previous Windows.
As long as you did an in-place upgrade from Windows 7, or Windows 8, to Window 10, no more than 30 days ago.
Okay click on start menu and then hit on settings now on the setting page click on upgrade and security button.
Now click on recovery and undergoing back to Windows click on get started And that's it.
After asking a few questions to confirm the rollback process will start.
In my experience it took about five minutes to half an hour depending on how fast the computer is.
Now note that once rollback some apps may need to be reinstalled.
And you have to remember the password for previous Window.
Because the password for Windows 10, you have to change it after the upgrade.
Will not stick.
Now for step by step instructions, check out my write up at cnet.com.
And one thing is for sure, though.
You can go back to Windows 7, Windows 8, or Windows 8.1.
There's no way, I mean no way, you can go back to Windows 9. And that's because I'm **** Ngo this has been a how-to on how to safely change your mind.
