Update for Windows Security platform - KB5007651 (Version 1.0.2109.27002)

Me either cannot update this KB5007651

I attempted the fix given by the admin and had no errors and none after the scans and rebooted several times. I then went to the Windows Security application and went to Device performance and heath and enabled the windows time service which was disabled before hand(I never disabled it to my knowledge) and tried the update again and it was able to install no problem. I hope this can help others but I must have just got lucky. I am also running windows 11 I don't know if there is a solution for windows 10 if the problem exists there as well. If you require ay help let me know and I'll do the best I can

Its seems that Microsoft corrected this error and update went through with no issues.

Hi,

Thanks for your post in Microsoft Community.

I understand that you are encountering a Windows Security Platform Update error with error code 0x80070643.

You can try running the command prompt as administrator and execute the following command:

(The command prompt can be found by searching for cmd in the search bar.)

sfc /scannow 



Dism /Online /Cleanup-Image /ScanHealth 



Dism /Online /Cleanup-Image /CheckHealth 



DISM /Online /Cleanup-image /RestoreHealth 

After the command is executed, restart the computer, and then execute the following command again:

sfc /scannow 

After detecting no problems with the system, try installing the Windows Security Platform Update again.

Please feel free to let me know how it goes.
