How to Extend Windows 11 Rollback Period to Windows 10

When you upgrade from Windows 10 to Windows 11, Microsoft grants a default 10-day grace period to revert to the previous operating system without losing your files or installed applications. If you need more time to test the new interface and ensure hardware compatibility, you can extend this rollback window up to a maximum of 60 days using built-in Windows tools. This guide covers the exact command-line steps required to prolong your downgrade window before the original 10-day timer expires.

Important Requirements Before You Begin

• You must execute these commands within the initial 10-day window following your Windows 11 installation.
• The Windows.old folder located on your primary drive (C:\Windows.old) must remain intact. If you have deleted this folder or run Storage Sense cleanup, you cannot extend the period or perform a standard rollback.
• The maximum allowed value for the rollback window is 60 days.

Step 1: Open Command Prompt as Administrator

1. Click the Start menu or press the Windows Key.
2. Type cmd into the search bar.
3. Right-click on Command Prompt and select Run as administrator.
4. Click Yes if prompted by User Account Control (UAC).

Step 2: Check Your Current Rollback Window

To verify your current configuration, type the following command and press Enter:

DISM /Online /Get-OSUninstallWindow

The output will display the number of days currently remaining for uninstalling the update (the default is 10).

Step 3: Extend the Rollback Period

To change the uninstall window, use the /Set-OSUninstallWindow command along with your desired number of days (up to 60).

Run the following command to set the window to 60 days:

DISM /Online /Set-OSUninstallWindow /Value:60

Note: You can replace 60 with any number between 2 and 60 (such as 30 or 45).

Once executed, you will see a confirmation message stating: “The operation completed successfully.”

Step 4: Verify the New Setting

To ensure the new expiration date is active, re-run the verification command:

DISM /Online /Get-OSUninstallWindow

The output should now reflect the new value you specified.

How to Roll Back to Windows 10 Later

Whenever you decide to revert within your extended timeframe:

1. Open Settings (press Win + I).
2. Navigate to System > Recovery.
3. Under the Recovery options section, locate the Go back button.
4. Click Go back and follow the on-screen instructions to restore Windows 10.
