Does Changing Your Xbox Live Gamertag Delete Everything? No.

Safe & Supported

Changing your Gamertag does not delete games, saves, DLC, licenses, achievements, friends list, or subscription time.

Why It's Safe

Your Gamertag is just a display name / identifier. All your entitlements (game licenses, save data, subscription) are bound to your Microsoft Account (email), which remains unchanged.

Minor, Temporary Side Effects

• Very old games (pre-2010): A handful may show your old name in leaderboards until you re-earn a score.
• Re-sign-in required: Some games/apps prompt you to sign in again after the change.
• Friends must search new name: Your old Gamertag becomes available for others after 30 days; friends need to re-add you if they search the old one.

How to Change

1. Press Xbox button → Profile & system → My profile → Customize profile.
2. Choose new Gamertag (first change free, then $9.99).
3. System updates across all devices automatically.

It's a routine, risk-free feature. Change away!
