Answer 1

Hi Luis Cuebas,

Thanks for reaching out to Microsoft Q&A Forum. I understand that you are getting install error 0x800700e9 when trying to install Security Intelligence Update for Microsoft Defender Antivirus - KB2267602 (Version 1.445.13.0) on Windows 11.

Please make sure you already tried the Q&A Assist steps. In addition, please try the following.

Does the error happen only in Windows Update, or also if you run a manual Defender signature update command? Are you using any third-party antivirus, VPN, or proxy on this PC?

In the meantime, you can try these steps:

1, Run a manual Defender signature update from PowerShell (Admin)

• Open PowerShell as administrator
• Run: Update-MpSignature -UpdateSource MMPC -Verbose

2, Reset Defender definitions cache, then update again

• Open Command Prompt as administrator
• Run: %ProgramFiles%\Windows Defender\MpCmdRun.exe -RemoveDefinitions -All
• Then run: %ProgramFiles%\Windows Defender\MpCmdRun.exe -SignatureUpdate
• If Tamper Protection is enabled, temporarily turn it off, re-run the two commands above, then turn it back on

3, Use the official offline security intelligence updater package

• Download the latest security intelligence update package from Microsoft Security Intelligence, then run the downloaded file to apply the definitions
• Link: https://www.microsoft.com/en-us/wdsi/defenderupdates

4, Check Defender-related services status

• Open PowerShell as administrator
• Run: Get-Service WinDefend, WdNisSvc, wscsvc
• If any are stopped, restart the PC and try step 1 again

5, Repair system files, then retry the update

• Open Command Prompt as administrator
• Run: DISM /Online /Cleanup-Image /RestoreHealth
• Then run: sfc /scannow
