Hi Ramesh,

I have been dealing with this issue for a week and have tried many different solutions provided in these forums, but none are helping. I did as you said and provided here the details of the scan for you to look deeper. Thanks

Answer 1

Thank you, Ramesh. My windows security is finally working properly.

Thank you for helping users like me on the daily, it truly is a blessing!

Have an amazing day.

You're most welcome :)

Thanks for the update.

Answer 2

Did the steps and still did not work. Windows security still says page not available and that I have to contact the IT team.

Please right-click defender_diag.bat and choose Save link as in your browser. It queries Defender settings.

Right-click on the downloaded file and click Properties. Select "Unblock" and click OK.

Double-click the batch file to run it. Share the output log (%temp%\defender.log) on GoFile.io.

Hi @Ramesh and @quietman7,

Answer 4

Thanks @quietman7.

@Matthew C11:

Please download the Windows Security platform update: https://catalog.s.download.windowsupdate.com/d/msdownload/update/software/defu/2025/04/securityhealthsetup_1528aebc5e90a333bf0f8a3f0d98b458311581fa.exe

After downloading the file, right-click on the file and choose "Run as administrator".

Restart Windows and see if that fixes Windows Security.

(Let me know the outcome of the above steps. If necessary, a fixlist can be prepared to resolve the issue.)
