This is only compatible with Windows 7, 8 and 8.1
Not everyone wants to upgrade to Windows 10. And while Microsoft say that drivers from 7, 8.1 "should" work. This statement by no means says they "will".
So with mission critical systems currently running 7 or 8.1, it is advisable to refrain from the shiny new Windows 10. Until you are absolutely sure frustration does not ensue.
To disable it, add the following registry key:-
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Gwx
Named :DisableGwx
type : REG_DWORD
Value : 1
Method example– create batch file:
1. Copy the following command into notepad,
reg add HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Gwx /v
"DisableGwx" /t REG_DWORD /d 00000001 /f
2. Save as to C:\Disable_Windows10_upgrade_notification.BAT file:
3. Right click C:\Disable_Windows10_upgrade_notification.BAT and choose
“Run As Administrator”.
4. Done.
