The Windows 11 lock screen will time out and shut off your display in less than 30 seconds — but what if you want it to stay on longer? You’ll need to edit the registry to enable the timeout settings in Windows 11. Here’s how to edit the registry.
Enable the Setting in the Registry Manually
Windows 11 doesn’t display the option to change the lock screen timeout setting anywhere by default. The most similar settings are the display timeout settings when your PC is not locked.
Warning: The Windows Registry is critical to the Windows operating system and most programs you have installed. Incorrectly modifying or deleting registry entries can result in system instability or inoperability. You should read about the Windows Registry and how to use the Registry Editor safely before trying this.
You’ll need to use the Registry Editor (RegEdit) to enable the setting before you can change it.
Begin by launching Regedit — open up the Start Menu, type “regedit” into the search bar, then hit Enter or click “Open.”
Navigate to the following address in RegEdit:
Tip: You can just paste the path provided into the address bar in RegEdit.
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlPowerPowerSettings7516b95f-f776-4464-8c53-06167f40cc998EC4B3A5-6868-48c2-BE75-4F3044BE88A7
Double-click the DWORD named “Attributes” to modify its value.
Change “Data Value” from 1 to 2, then click “OK.”
That is the only thing you need to change in the registry, so close out RegEdit.
If you ever want to disable the option, just change the value back to 1.
Use Our REG Files to Automate The Process
If you don’t want to go digging through the registry manually — and there are plenty of reasons to want to avoid it — you can just use our pre-made REG files to apply the changes automatically.
Warning: REG files just apply preset changes to the Windows Registry based on the contents of the file. Generally, you shouldn’t trust random REG files you download off the Internet — they could be malicious. You can check any REG file by opening it in a plain text editor. It is normal to see a warning popup whenever you try to apply a REG file you downloaded or made yourself. If the source is trustworthy or you’ve checked the file, just hit “Run” and “Yes” when prompted.
