Quote:Launch the Registry Editor by typing its name in the Start menu or regedit.msc in the Run dialog (Windows key + R). Navigate to the following path:

Code:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

The right side of the window groups all registry items that are related to the policies on your system, and once again, the one that you need to edit is called:

Code:

InactivityTimeoutSecs

If this key does not exist, you need to create it manually using the following steps:

Code:

Right-click in right pane > New > DWORD (32-bit Value) > InactivityTimeoutSecs

Double-click this item to change its value and once again, you need to enter a value between 0 (disabled) and 599940 (9999 minutes). Click OK, close the Registry Editor, and reboot your system to apply the new settings.
If you want to disable this automatic lockdown of the system at a later time, you can just change the value of the registry key to 0 or delete it (if you’ve created it manually).
