There is no other disk involved. The issue has been inherent for several months and exhibits in wrongly reporting 100% Free for system partitions.

I can't speak to that... I don't HAVE "system partitions".
When I installed Windows 10, I installed it so all the Windows partitions would be on the C:\ drive...
Disk 0 is MBR btw.
Disk 1 and Disk 2 are GPT






Yes, I admit it. I'm a Windows rebel. I think MS must have "wanted posters" with my face on them.

@Win7ine



As I'm sure you can see, my "system" partition is ON my C:\ drive...






So..... I can't speak to WHY yours show 100% free. I have nothing to compare to.

Someone WITH an EFI system partition will have to respond.

I just ran SFC myself. I'm on 21H1. I get zero errors.
Then again... I don't use/have the snipping tool?

As I understand it, in 21H1 you should now see Snipping Tool on the Start menu under 'Accessories', not 'Windows Accessories' as it is in 20H2/2004.

2 Pro and 1 home done, took around 5 minutes for each, all had SFC errors all fixed, no issues with health. Other than that all seems fine.

Mine is still under Windows Accessories.

Oh I think you'll find it's been around a lot longer than that. I believe it's a permission issue, even as an administrator you don't have sufficient permission to enumerate the contents of the EFI partition. I don't recall seeing anything other than '100% free' from the original 1507/10240 release onwards. Here it is in 1803...

I found the KB number for the SSU in the MS info page for this CU
https://support.microsoft.com/en-us/...f-d67fec538490

It is KB4598481 {issued in January} so no new one is required before installing this CU.

CU updates include SSU from now on. That's what I showed in a UUP dump.

It is a reporting issue and not a permission issue. It has been discussed here in the past. EFI and! RECOVERY and perhaps others hidden are affected. It appeared after 19041.630 or so. Never seen it before.
