Quick steps to reinstall Windows 10

GPD Win - How To Reinstall Windows 10 - Auto Activation and Clean Anniversary Build (WiFi Works!)

1. Download Double Driver and make a full backup of drivers in compressed form
2. Download Windows Media Creation tool and flash the iso to USB (this can be done on any computer or the GPDwin itself)
3. Go to advanced settings and reboot off of USB diskAt this point your screen will be in portrait mode as that's the default position of the screen.
4. Delete all Drive 0 partitions
5. Click Next
6. Windows 10 start-up, configure to specifications (I disable everything) Enter your username click continue
7. Load Double Driver portable and your compressed driver back up. Restore everything. (Double Driver will auto check things that need to be installed)
8. It invokes the Windows Device manager to install drivers.
9. After that's done rotate screen 270 degrees (which is how you want it) and click disable rotation from Windows Notification menu.
10. reboot
11. To get wifi working you need to replace a txt file in your driver directory. GPD made a batch file that you can just run as administrator. (https://www.mediafire.com/?auzcacssci9i97r)
12. reboot
13. Ta-da! You're on a clean install of anniversary edition.

Step 11

If the mediafile link is unavailalbe create the following files using a text editor and run the batch file as an administrator.

WiFi.bat
