How to Disable and Enable the Meltdown and Spectre Patches from Slowing Down Your PC

  

The Windows patches for Meltdown and Spectre will slow your PC down. On a newer PC running Windows 10, you probably won’t notice. But, on a PC with an older processor—especially if it’s running Windows 7 or 8—you may see a noticeable slowdown.

You can also disable the protection in the registry yourself, if you like. Run the commands under “To disable this fix” on this Microsoft support page. Restart your PC after changing the registry settings. If you change your mind and want to re-enable the protection in the future, run the instructions under “To enable the fix” on the Microsoft web page.

You can use batch files to enable or disable the fix.
