Solve Error 0x803f900a: Xbox & Windows Fixes

Error 0x803f900a appears when your Xbox console or Windows PC cannot verify that you own a game or app, usually because of a licensing or sign-in problem. The fix is to sign in to your Microsoft account, check your network connection, and if needed, reinstall the game or restore licenses. Below are the exact steps for both platforms, plus what causes the error and how to avoid it.

What Error 0x803f900a Means

This error code is tied to Microsoft’s digital rights management (DRM) system. When you launch a game or app, your device contacts Microsoft’s servers to confirm that your account has a valid license. If that check fails, you see 0x803f900a. It can happen for several reasons:

You are signed in with a different Microsoft account than the one that owns the content.
Your console or PC is offline or has a weak connection to Xbox Live.
The license file on your device is corrupted or out of sync.
You are playing on a console that is not set as your home Xbox, and you are offline.
There is an outage on Microsoft’s side.

It is not a hardware failure and rarely means your game is broken. It is almost always a licensing or authentication hiccup.

Fix on Xbox One and Xbox Series X/S

On an Xbox console, the error usually appears when you try to start a digital game. Try these steps in order:

Check Xbox Live status. Go to the Xbox support website or look at the network settings on your console. If there is an outage, wait until it is resolved.
Sign in and out. Press the Xbox button, go to Profile & system > Add or switch, and select your profile. If you are already signed in, sign out and sign back in. This refreshes your authentication token.
Restart the console. Hold the power button on the front of the console for 10 seconds until it turns off. Unplug the power cord for 30 seconds, then plug it back in and turn it on.
Make sure the console is online. Go to Settings > General > Network settings > Test network connection. If it fails, troubleshoot your router or modem.
Set your console as your home Xbox (if you are the primary user). Go to Settings > General > Personalization > My home Xbox. If it is not set, select “Make this my home Xbox.” This allows offline play and lets other profiles on the console use your games.
Reinstall the game. Highlight the game, press the Menu button, select Manage game and add-ons, then Uninstall. Then reinstall from your library. Your saves are stored in the cloud, so you will not lose progress.

If the error persists after reinstalling, try the “Restore licenses” option (see below).

Fix on Windows 10 and Windows 11

On a PC, the same error can appear in the Xbox app or Microsoft Store. The cause is often a corrupted store cache or a licensing issue with the Microsoft Store.

Sign in with the correct Microsoft account. Open the Microsoft Store, click your profile icon, and verify you are using the account that purchased the game. If not, sign out and sign in with the right one.
Run the Store Apps troubleshooter. Go to Settings > System > Troubleshoot > Other troubleshooters (Windows 11) or Update & Security > Troubleshoot (Windows 10). Select “Windows Store Apps” and run it.
Clear the Microsoft Store cache. Press Win + R, type wsreset.exe, and press Enter. A blank Command Prompt window will open and close when done. This does not remove your apps or games.
Repair or reset the game or app. Go to Settings > Apps > Installed apps, find the game, click the three-dot menu, and choose Advanced options. Click Repair first. If that does not work, click Reset (this may delete local data, but cloud saves remain).
Reinstall the game. If repair/reset fails, uninstall and reinstall from the Microsoft Store or Xbox app.
Check your date and time. An incorrect system clock can break license checks. Go to Settings > Time & Language > Date & time and enable “Set time automatically.”

Restore Licenses on Xbox

If you have tried the basic steps and still get the error, restoring licenses can help. On Xbox One and Series X/S:

Press the Xbox button to open the guide.
Go to Profile & system > Settings > Account > Licenses.
Select “Restore licenses.”

This forces your console to re-check all your digital licenses. It does not affect your saved games or achievements. After it finishes, restart the console and try the game again.

Common Causes and How to Avoid Them

Most users see this error after they switch accounts, share a console, or go offline for a long time. Here are the most common triggers:

Game sharing. If you set another console as your home Xbox so a friend can use your games, your own console must be online to play those games. If you go offline, you get this error.
Account changes. If you changed your Microsoft account password or security info, your device might need to re-authenticate.
Store updates. A pending update to the game or the Store app can cause a temporary license conflict.
Regional mismatches. If you purchased a game in one region and then change your console region, the license may not match. Keep your region consistent.

To avoid the error in the future, always keep your console or PC online when playing games you do not own on that specific device, and make sure your account is signed in before you launch a game.

What to Do If Nothing Works

If you have tried all the steps above and still see 0x803f900a, there are a few final options:

Check for system updates. On Xbox, go to Settings > System > Updates. On Windows, go to Settings > Windows Update and install any pending updates.
Try a different network. Sometimes your ISP or router blocks the licensing servers. Try using your phone as a hotspot to see if the game launches.
Contact Microsoft Support. If you are sure you own the game and the error persists, there may be a problem with your account or the license itself. Microsoft support can check your purchase history and refresh the license on their end.

Do not try to bypass the DRM or use cracked versions of the game. That can lead to account bans and security risks. The error is almost always fixable through official channels.

Frequently Asked Questions

Why does error 0x803f900a happen even when I am online?

Being online is not enough if your account is not authenticated. If you have not signed in recently, or if your password changed, the license check can fail. Sign out and sign back in, and make sure your console or PC has the correct time and date.

Will I lose my saved game if I reinstall?

No. Saved games are stored in the cloud for Xbox and most Microsoft Store games. When you reinstall, your saves will sync automatically as long as you are signed in with the same account. On PC, some older games may store saves locally, so back up the game folder if you are unsure.

Can I play a game I bought on another console?

Yes, but only if you are signed in with the account that owns the game. If you are on a console that is not your home Xbox, you must be online to play. The same applies to PC: you can play on any device, but you need an internet connection to verify the license.

Does this error mean my game is banned or revoked?

No. It is a temporary licensing failure, not a ban. If you purchased the game legitimately, you will be able to play once the license is restored. If the error persists after all fixes, contact Microsoft support to verify your purchase.

Is there a way to fix this without reinstalling?

Yes. Start with the simplest fixes: sign out and back in, restart the device, and check the network. On Xbox, restoring licenses often works without a reinstall. On Windows, running the Store troubleshooter or clearing the cache is usually enough.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
