One month has passed (if Microsoft keeps its word) that the prompts for upgrades to Windows 10 will continue to disturb users of older systems.
Although you are also a user of it Windows 7 or Windows 8.1, and you are bothered by Microsoft below we will see a different way to prevent the upgrade to Windows 10.
Follow the instructions:
Start the Registry Editor by searching for regedit.
Follow the route:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Image File Execution Options
Create a new key called GWX.exe by right-clicking on the “Options implementationof the file image".
With the GWX.exe key selected, right-click the empty area on the right and select New String Value.
Name the value 'Debugger' and double-click on it.
In data of the Debugger value, type:
rundll32.exe
Click OK and close Registry Editor.
That's it. Now the Windows 10 Upgrade application should not run on your system even if the update that installs Get Windows 10 (KB3035583) is installed on your computer.
This tweak should work as long as the executable name that starts upgrading to Windows 10 is called GWX.exe. If the file name changes, simply change it to the Registry.
For those who can not follow the steps above, download the .zip and double-click on the file you find inside. The .zip file contains two files, double-clicking Reg to Stop GWX.reg, you apply the above changes, and double-click Reg to Undo Stop GWX and allow it.reg restore your system as before.
