Because browser sign-in works but Microsoft app sign-in fails in Xbox app, Microsoft Store, and Minecraft Launcher, this points to a Windows-side sign-in/authentication problem rather than a real internet outage.
Try these steps in order:
- Reset the Microsoft Store cache.
- Press Windows key + R.
- Run wsreset.exe.
- Wait for the blank Command Prompt window to close and for Microsoft Store to open automatically.
- Then try signing in again.
- Restart the PC.
- A restart is specifically recommended in several Microsoft sign-in and Store troubleshooting cases.
- Reset the affected apps.
- Go to Settings > Apps > Apps & features.
- Open the advanced options for Xbox app and Microsoft Store.
- Use Reset.
- Then sign back in.
- Turn off VPN or proxy temporarily, if in use.
- Network-related sign-in failures for Xbox app and Minecraft Launcher are commonly associated with VPN/proxy interference.
- Sync Windows date and time, then test again.
- Incorrect system time can interfere with Microsoft account sign-in components.
- If the issue affects all Microsoft apps only on this Windows profile, test with a new local Windows account.
- Go to Settings > Accounts > Other users > Add account.
- Select I don’t have this person’s sign-in information.
- Select Add a user without a Microsoft account.
- Sign in to that new profile and test Microsoft Store or Xbox sign-in there.
- If sign-in works in the new profile, the original Windows profile’s authentication state is damaged.
- If the problem also happens in the new local account, repair Windows using Windows Update reinstall.
- Go to Settings > System > Recovery > Fix problems using Windows Update > Reinstall now.
- This repairs Windows while keeping files, settings, and installed apps.
- If needed, perform a Windows network reset.
- Go to Settings > Network & Internet > Advanced network settings > Network reset.
- Restart the computer after the reset.
The most relevant first path for this exact symptom is: wsreset.exe → restart PC → reset Xbox app and Microsoft Store → test in a new local Windows account.
