Why I can't enable the 49221331 ID for some reason

It sounds like you're facing issues enabling the 49221331 ID feature in the Start menu on the Dev Channel build 26120.2705. There could be several reasons for this problem. First, ensure that you're following the correct steps to enable the feature, such as modifying the appropriate registry keys or using the correct settings in Windows. Sometimes, features in preview builds may not work as intended due to bugs, so it's possible that this feature isn't fully functional yet in your current build. 

Not all features in the Dev Channel build are immediately stable or available to all users. Sometimes, features are gradually rolled out, and you may be in a segment that hasn’t received the update yet.

Ensure that you have the latest updates for your build. Sometimes features may not work as intended if you’re not on the latest version. Not all features in the Dev Channel are guaranteed to be available to all users simultaneously. It's possible that the feature you're trying to enable isn't rolled out to everyone yet, even on the same build.

Hello,

I can give some suggestions at this point.

Ensure You're Using the Latest ViVeTool Version:

Make sure you are using the latest version of ViVeTool compatible with your build.

Run the Commands in Elevated Command Prompt:

Verify that you opened the Command Prompt as Administrator before running the commands. If not:

• Search for cmd in the Start Menu.
• Right-click and choose Run as Administrator.

Enable the Feature Again:

Re-run the enable command, but include the restart flag to ensure the changes take effect: vivetool /enable /id:49221331 /restart

Verify Build Compatibility:

Confirm that the 49221331 feature is available for your specific build (26120.2705). Some features might not be fully implemented or enabled for your Dev Channel version yet.

Manually Check the Registry Key (Optional):

If the issue persists, check the Windows Registry to see if the feature flag is applied:

• Open the Registry Editor (regedit).
• Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FeatureManagement\Overrides
• Search for an entry related to 49221331 and ensure its EnabledState is set to 2.

Clear Cache and Re-Enable (Force Refresh):

• Sometimes, cached configurations can interfere. Try clearing and reapplying the changes:
• vivetool /reset /id:49221331
• vivetool /enable /id:49221331 /restart

Restart Your PC:

• Restart the system to apply changes properly.
