He has not been doing a Repair install ever since post #2 so he is unlikely to bother now. #2 #5 #7 #15 #26 #33 and now #36 All the best, Denis

@Try3 Thank you for your quick response. You have always been quick to respond. This morning I updated the HP laptop to 21H2 through the normal Windows update. Do you still think I should do a repair install with 21H2 ISO? I am posting three screenshots .





I am yet to try the suggestion made by @hdmi in his post #8 "See also options 2 and 3 in this tutorial: Windows Defender not updating automatically in Windows 11/10" I shall try it later tonight and report to hdmi. He must be waiting in the wings.

 

[Solved] Windows defender-not updating-Engine unavailable

Can't read. Lost my spectacles.*chuckle *Focus @Try3, CrogramData\Microsoft\Windows Defender -RemoveDefinitions -All --- No engine/signature is currently loaded. Engine version:0.0.0.0

-Remove Definitions -Engine --- No engine/signature is currently loaded. Engine version:0.0.0.0

Copied the folders "Definition Updates" and "Platform" (CrogramData\Microsoft\Windows Defender) on my Dell Desktop to a pendrive Backed up the two folders on the HP laptop as backup to the same pen drive - just incase I need to restore those (after deleteing the files in it ). Tried to delete the files in the 'Definition" updates and "Platform" folders in the HP laptop. Windows yelled at me "You idiot, don't you know you require permission from SYSTEM to make changes to this folder?" I said "OK chum, I will put you to sleep and gag your mouth" Plugged in the Macrium Reflect WinPE pendrive and the pendrive where I had saved the the two folders from my Dell laptop, booted into MR WinPE, navigated to the "Definition Updates" and "Platform' folders and deleted all the files in it. Copied the files from my Dell laptop to the respective folders on the C: drive, closed Macrium Reflect and Voila! all done when the HP laptop booted.

Success. All is well now. No more engine unavailable message



Proof of the pudding is in eating.( Oops its lunch time and I am already hungry) Luckily the latest Security intelligence was available and Windows update downloaded and installed it Updating:

Update finished



The end. A thanksgiving post after lunch.
