Quote:The Registry Editor method basically comes down to defining the aforementioned policy manually. So the first thing to do now is to launch the Registry Editor by typing regedit.exe in the Start menu.
Then, navigate to the following path in the Registry Editor:

Code:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System

On the right side of the screen, there should be a policy that is called:

Code:

PublishUserActivities

If it does not exist, you can simply create it manually by just right-clicking in the right pane and then go to New > DWORD (32-bit) Value. Use the name mentioned above.
Depending on the value that you give to PublishUserActivities you can allow the Activity History tracking or not.

Code:

Value 0 = Disabled
Value 1 = Enabled

If you want to disable Activity History on your device, double-click this new item and input value 0. Reboot your system and now Activity History should be blocked completely.
