To perform a clean sweep: Phase 2: The Uninstall Protocol The only definitive

1. Use the Microsoft Support and Recovery Assistant (SaRA): This automated tool is the gold standard. Run the "Office uninstall" option. It scrubs every vestige of the preview, including hidden services and licensing certificates.
2. Manual Cleanup (If SaRA fails): Navigate to %ProgramFiles%\Microsoft Office\Office16 and %ProgramData\Microsoft\OfficeSoftwareProtectionPlatform. Delete the OSPPREARM and Tokens.dat files.
3. Registry Purge: Using Regedit, delete the keys under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\16.0\Licensing and HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\Licensing. Warning: Backup your registry before proceeding.

Important: Understanding the Situation

• The Expiration is Intentional: Preview (beta) versions of Office are designed to stop working after a specific date to force users to upgrade to the official release.
• Preview vs. Official: You are likely running version 16.0.14332.xxxxx or similar. The official release is a newer, stable build.
• Warning: Do not attempt to use third-party "activators" or cracks. These often contain malware and are illegal. The correct method is a clean installation.

Q2: Will I lose my documents if I uninstall Office?

A: No. Uninstalling Office removes the application only. Your .docx, .xlsx, and .pptx files remain untouched. However, back them up first just in case.

Method 4: Adjust System Date (Temporary Workaround Only)

If you need to access a critical document for a few minutes before performing the proper fix, you can trick the license check by changing your system date.

Important: This is a temporary emergency measure. It will break other applications (browsers, HTTPS websites, antivirus).
