Windows 10: IsInstallable / IsInstalled rules for 20H2 Feature upgrade

What are the rules for detecting 20H2 feature update?I have a machine with 20H2 installed. But it keeps reporting to MEMCM, that it is 20H1 and needs to upgrade every day - including reboot prompt.I even installed 21H1 yesterday manually - successfully! The next update scan/evaluation cycle again wants to install 20H2 and prompts for reboot.Did sfc /scannowDISM /Online /Cleanup-Image /RestoreHealthwinmgmt /resetrepositorydeleted root/ccm namespace from wimThe next scan/evaluation cycle always says "oh, I need to install 20H2!"

developing WindowsUpdate Custom Control Function of Windows10

Hello.

I'm developing WindowsUpdate Custom Control Function of Windows10.(and the lower versions already completed.

I'm using IUpdateSearcher2, and the code is below.

sQuery = _T("isinstalled=1");

pUpdateSearcher->Search(CComBSTR(sQuery), &pResult);

I thought, this function is usable in the Windows Power Shell, so, I found the script, and execute the query in Windows 7, and it worked!

But, I run the query in Windows 10, but it didn't worked.

So, I'm just qurious. Is there any method to query Windows Core Update List using PowerShell or any other methods in Windows 10?

$Session = New-Object -ComObject Microsoft.Update.Session

$Searcher = $Session.CreateUpdateSearcher()
$Criteria = "IsInstalled=1 or IsInstalled=0"
$SearchResult = $Searcher.Search($Criteria)

$SearchResult.Updates

It works in Windows 7(return update list), but dosen't work in Windows 10.(return 0 list)

(When I firstly installed Windows10, it partitially worked. some lists returned, but all didn't. I need Windows Update Full list.)

(I don't want Get History Query, I also need list to update[receive])

I also tried to reload the latest drive on the official website and still can't use it.
Special to ask for your assistance.

Windows 10 20H2 Upgrade

I doubt it is a glitch. I suspect it was designed that way.
