## Windows 10 cleanup script.
## Remove dodgy tracking settings, unneeded services, all apps, and optional features that come with Windows 10. Make it more like Windows 7.
##
## Instructions
##  1. Start Windows 10 installation. At the first point you are asked for input during Windows 10 setup, hit Shift-F10. This gives you a command prompt.
##  2. Now mount a network volume, or insert a USB key with this script on it and change directory to it. e.g.
##     net use x: \\mynetworkmount
##     cd x:
##  3. Run the script
##     powershell -ExectionPolicy Bypass cleanup-win10.ps1
##  4. Let it run through, you may see a few errors, this is normal
##  5. Reboot
##     shutdown /r /t 0
##  6. Contine installation as normal
##  7. Once you login for the first time, run this script again (under Powershell as Administrator):
##     powershell -ExectionPolicy Bypass cleanup-win10.ps1
##  8. Go through the "Things to do after" shown at the end of the script
##  9. Done!
