To re-enable the Windows 10 update remove the DWORD values above.
Set the DWORD (32-bit) “ReservationsAllowed” (Hexidecimal) value to 0. Set the DWORD (32-bit) “AllowOSUpgrade” (Hexidecimal) value to 0. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade Select the “WindowsUpdate” key and create a new DWORD (32-bit) value name it “DisableOSUpgrade” and set its value (Hexidecimal) to 1. Create a new key under the “Windows” key and name it “WindowsUpdate”. Select the “GWX” key and create a new DWORD (32-bit) value name it “DisableGWX” and set its value (Hexidecimal) to 1. Create a new key under the “Windows” key and name it “GWX”. Navigate to the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows. Type Regedit in RUN or Start search box and press Enter (to open the Registry Editor). You can do this automatically by running the “Disable GWX” registry script from here and then rebooting your computer, otherwise you can follow these manual steps: Click “Go back to Windows 7” or “Go back to Windows 8.1”. If the new version of Windows has already installed itself on your computer (within the last 31 days), it is still possible to revert to your previous version of Windows using these instructions: Windows 10 is an improvement over Windows 8.1 and arguably over Windows 7 but if you’d rather wait to install it on your own terms, you’ll need to adjust some settings (instructions below). If you have Windows Updates configured to automatically install updates on your computer, then it’s a matter of time before your computer updates itself too (if it hasn’t already). You may have heard reports of computers with Windows 7 or 8 automatically updating to Windows 10.
