I'm in the process to upgrade the W803T CSC Wisebook Windows Tablet from Home to down stripped Windows 10 Pro 1709. The W803T is a low power Intel Windows Tablet which initially come with Windows 8.1Home. CPU is an Intel Atom Z3735F Quad Core, 1GB RAM and 16GB ROM. That procedure is a bit more complicated on a Tablet with just 1 Mini USB port than on a PC and/or Laptop. There several 'special' needs: OTG Connector (USB to Mini USB) OTG Splitter Cable with USB and Power in (to the Tablet) and Mini USB into the Tablet 4 Port USB Hub USB Keyboard USB Mouse USB Flash Drive 4-8GB, formatted to Fat32 (NTFS will not work) Prepare the USB Flash Drive by formatting to Fat32. Mount the OS ISO File and manually copy the content to the USB Flash Drive. I was trying to create that with Rufus and failed: booting from the Flash Drive impossible, so I end up going the manual way which worked just fine. I create a down stripped Windows 10 Pro 1709 and used to add all from the Home version saved drivers into the install.wim which worked just well except for the Accelerometer, which I needed to install manually by pointing the Device Manager to the location of that files. In Device Manager, it was shown as unidentified Device. Now the install is finished and I've to configure the Pro in several details, which will need a bit of time. The used space for the whole installation is 7GB on that 16GB ROM, while the full Home edition was needed 9+GB's! Who like to go a similar way, will need to first to know how to start to boot from an external USB Flash Drive. That said, the User must first know how to enter the BIOS of that Tablet and allow the boot from USB Drives/Devices. From within a running Windows 8.1/10, open Settings, go to Update & Security, click on Recovery, and under Advanced startup click on Restart now which will restart into Recovery Mode. If the Tablet is using EFI, you could now see: Use a device. Click on that and you'll have the choice between USB Device, DVD/CDROM, and Network. If the USB Hub with Keyboard, Mouse, and USB Flash drive is already connected to the tablet, you may already see the named USB Flash drive. Just click on that and the Tablet will boot from the USB Flash Drive. Now the setup and installation of Windows could be started. As I had the first problem with the OTG Splitter Cable, I suggest starting the whole procedure with a fully charged Battery of the Tablet only! I also tested a multi OTG Cable which was not working correctly. The use of a WiFi/Wireless Keyboard and Mouse, will not work (it didn't in my case), USB is needed. Any question? Please let me know. Thanks.
