How to Enable or Disable Sleeping Tabs on Edge

In Edge, the sleeping tabs feature, which uses “freezing” technology, puts inactive background tabs to sleep after a certain amount of time.

Thus, the system resources (RAM and CPU) allocated to inactive tabs are made available to other tabs or applications.

Here are the steps to activate this feature.

Open Edge browser.

Click on the three horizontal dots in the upper right corner.

Hit Settings.

Hit System on the left sidebar.

There is a switch beside Save resources with sleeping tabs in the Optimize Performance section. Activate it.

You can also see a drop-down list next to “Put inactive tabs to sleep after the specified amount of time.”

Self-explanatory, isn’t it?

Open it and choose your desired duration. The following durations are available:

  • 5 minutes of inactivity
  • 15 minutes of inactivity
  • 30 minutes of inactivity
  • 1 hour of inactivity
  • 2 hours of inactivity
  • 3 hours of inactivity
  • 6 hours of inactivity
  • 12 hours of inactivity

Notes:

You can prevent some sites from being put to sleep by clicking the Add button next to Never put these sites to sleep.

You will see a pop-up when you click the Add button. Once you’ve entered the URL, click on Add.

If you want to remove a page that has been added, press the three horizontal dots beside it and click Remove.

Edge has a heuristic that prevents some sites from being put to sleep since these sites do not work when they are put to sleep.

Clicking on the sleeping tab will activate it.

Deactivate the sleeping tabs feature by turning off the switch beside Save resources with sleeping tabs.

Here are the alternate methods:

Method #1

If Microsoft Edge is already running, close it.

Open the Registry Editor. Before proceeding, I suggest that you backup the Registry.

Go to HKEY_LOCAL_MACHINE > SOFTWARE > Policies > Microsoft.

Hit Edge. If you can’t find it, you will have to create it. You can do this by right-clicking on Microsoft and choosing New > Key. Press the Enter key after entering Edge.

Right-click on the blank space in the right pane.

Select New > DWORD (32-bit) Value.

Then enter SleepingTabsEnabled and press Enter. Double-click it.

In the Value data field, enter 0 (always disabled) or 1 (always enabled).

Hit the OK button.

That’s all.

Note: Removing the DWORD you created earlier will restore the default setting.

Method #2

To Enable:

Launch local group policy editor.

Navigate to the Computer Configuration > Administrative Templates > Microsoft Edge > Sleeping tabs settings.

Then double-click “Configure sleeping tabs” in the right pane.

Select Enabled.

Hit the OK button.

That’s all.

Note: Follow the steps above but choose Disabled to disable sleeping tabs.

Here’s how to change the sleeping tabs timeout using the local group policy editor:

Launch local group policy editor.

Navigate to the Computer Configuration > Administrative Templates > Microsoft Edge > Sleeping tabs settings.

Then double-click “Set the background tab inactivity timeout for sleeping tabs” in the right pane.

Select Enabled.

Choose the timeout you prefer from the drop-down list.

Hit the OK button.

That’s all.

If you want to change the sleeping tabs timeout using Registry, then follow these steps:

If Microsoft Edge is already running, close it.

Open the Registry Editor. Before proceeding, I suggest that you backup the Registry.

Go to HKEY_LOCAL_MACHINE > SOFTWARE > Policies > Microsoft.

Hit Edge. If you can’t find it, you will have to create it. You can do this by right-clicking on Microsoft and choosing New > Key. Press the Enter key after entering Edge.

Right-click on the blank space in the right pane.

Select New > DWORD (32-bit) Value.

Then enter SleepingTabsTimeout and press Enter. Double-click it.

Now enter any of the following values in the Value data field as per your preference.

  • 300 – 5 minutes of inactivity
  • 900 – 15 minutes of inactivity
  • 1800 – 30 minutes of inactivity
  • 3600 – 1 hour of inactivity
  • 7200 – 2 hours of inactivity
  • 10800 – 3 hours of inactivity
  • 21600 – 6 hours of inactivity
  • 43200 – 12 hours of inactivity

Hit the OK button.

That’s all.

Note: If you want to use the drop-down list to change the timeout for sleeping tabs, then you will need to delete the DWORD you created earlier.
