| Step | Action | Expected Result |
|---|---|---|
| 1️⃣ | Right-click Teams.exe > Properties > Compatibility tab | Sets run mode |
| 2️⃣ | Check "Run this program in compatibility mode for: Windows 8" | Bypasses Win7 flag |
| 3️⃣ | Apply > Run as admin | Error gone! |
Registry bonus (advanced users): Edit HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp\DefaultSecureProtocols to 0xAA0 for TLS tweaks. Caution: Backup registry first!
