    Restart your computer and check if windows update is running properly.

    If issue persists,

    Try running windows update after temporarily disabling bitdefender protection:

    If the issue still persists,

    Generate bitdefender BDsysLog:

    Generate bitdefender support tool logs:

    Generate bitdefender connectivity logs:

    Share the logs & your query with bitdefender support team by dropping them an email at [email protected]

    If the generated logs are larger in size, you can upload the logs to google drive or (7days link validity for free users) or ask the support team to provide you with the online link & password of bitdefender cloud where you can upload the logs and share the upload link with the support team.

    The support team will reply back to your query within next 24-48 hours excluding weekends.

  • I think this is not a Bitdefender related issue, but a Microsoft one..
