The Interrupting Lock
Windows 11 prioritizes security by ensuring your computer isn’t left open and accessible when you walk away. By default, if you don’t interact with your mouse or keyboard for a set period (often just a few minutes), the screen will turn off, and the system will automatically lock itself. When you return, you are forced to re-enter your PIN, password, or use Windows Hello to resume your session. While excellent for a busy office environment, this constant automatic locking is incredibly frustrating if you are reading a long document, watching a tutorial, or simply using the PC in the absolute safety of your own private home.
Extending the Timeout
To keep your session active and stop Windows 11 from automatically locking the screen after a brief period of inactivity, you must adjust the system’s power and sleep timers.
Press the Windows Key, type Settings, and hit Enter. In the left-hand navigation sidebar, click on System. In the main panel, click on Power & battery (or just “Power” on desktop PCs). Look for the section labelled Screen and sleep and click it to expand the options. You will see dropdown menus for both “Screen” (when the display turns off) and “Sleep” (when the computer locks and goes into standby). To completely stop the automatic locking, change the “On plug in, put my device to sleep after” setting to Never. If you want the screen to turn off but not lock the PC, leave the Sleep setting on Never, but change the Screen setting to 15 minutes. Note: if your PC is managed by a workplace IT department, these settings may be greyed out.
