There are two main methods to change or disable the lock screen timeout on Windows 10: using the Settings app or using the Registry Editor.

Method 1: Using the Settings app

  1. Open the Settings app.
  2. Click on “Personalization”.
  3. Click on “Lock screen”.
  4. Under “Screen timeout settings”, select the desired timeout period. You can choose from 1 minute, 5 minutes, 10 minutes, 30 minutes, 1 hour, 4 hours, or never.
  5. To disable the lock screen altogether, toggle the “Require sign-in after an idle period” switch to the off position.

Method 2: Using the Registry Editor

  1. Open the Registry Editor. To do this, press Windows key + R, type “regedit” and press Enter.
  2. Navigate to the following key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
  3. In the right pane, double-click on the “Console LockDisplayOffTimeout” value.
  4. In the Value data box, enter the desired timeout period in seconds. For example, to set the timeout to 5 minutes, enter 300 (since there are 60 seconds in a minute).
  5. Click “OK”.
  6. Restart your computer.

Additional Tips:

  • If you are using a domain-joined computer, the lock screen timeout may be controlled by your network administrator. In this case, you will need to contact your network administrator to change the timeout settings.
  • You can also use the Group Policy Editor to change or disable the lock screen timeout. However, the Group Policy Editor is only available on Windows 10 Pro and Enterprise editions.
