Defender and 1803

Having updated to 1803 from 1709 I now find when booting up defender takes a long time to complete.
When viewing the security centre blue dots are continually running on Virus threat protection and firewall and network. After about 1 minute the dots stop and the green tick appears. This is then followed by two Dcom errors in event viewer. So every time you boot you get these errors. Unfortunately APP ID and SID are unknown, yet it's telling you that this can be fixed with permission in Component Services.

This never happened in 1709. Both my machines suffer the same error. Not a big problem but, it's annoying to find this when the previous version on both machines was error free. Once again MS has taken one step forward and two steps backwards.

This issue is caused by 2 registry entries that point to Defender features that are only available on Windows Enterprise (and maybe Windows for Workstations).

I think it is safe to delete these keys, BUT since I have not tested this, I don't recommend it. Maybe MS will issue a small patch for this in the near future.

Thanks for the reply, will wait to see if MS puts out a fix before I hack the registry.

Does the old UI works? C:\Program Files\Windows Defender\MSASCui.exe
Win+Run+MSASCui.exe

As per slicendice statment - no.

Ok! The same effect is also true in 1709: MSASCuiL.exe does not open. We noticed that a few weeks ago on each upgrade attempt or even after a clean install(171xx.x). In the previous cycle, MSASCui.exe would take some 30 seconds to open, in this cycle they adopt a better strategy, it won't open.

Any changes in our favorite app get our immediate attention. 1803 will be 1803 when the normal condition will be restored.

It doesn't work for me either and I still find the old interface is better.
