Possibly the same answers you got here, if you recall the thread?
I forget stuff all the time. Apparently last weekend I asked my wife 3 times in the same day if she picked up my suit from the dry cleaners. Which reminds me, I should ask her if she picked up my suit from the dry cleaners?

Can you execute the batch script that is attached to restore Windows 11 services to default startup type and reboot, check if problem resolved?

FreeBooter · Apr 18, 2024

If the restoring services won't resolve the problem, then execute the attached batch script to re-register all DLL files.

There's likely a missing COM related subkey somewhere: Understanding DISM / Servicing Stack Interaction

Have you checked the DISM and CBS logs? It would be helpful if you uploaded them.

Hey , thanks.

I got bad news.
1) I tried repair install and at the end i took a message "Windows installation fails" (from ISO at the desktop. I dont know if
from USB there is something better)
2) The first batch works but the problem remains
3) The second batch dont work. It appears a flashing windows for 1 sec.
But i opened and i did the job manually. All dlls registered but the problem remains.

After all these i dont know if even a try for clean install will work.
Also i am waiting for an alternative solution in order to save my work.

I forget something that could indicates the problem.
While i reregister the dlls i took an error :

Translation : "Windows could not make the requested changes. The class is not registered. Error code 0x80040154. Troubleshooting instructions.". The link with the instuctions : https://learn.microsoft.com/el-GR/troubleshoot/windows-client/application-management/dotnet-framework-35-installation-error

I dont know if the message is for all or some or 1 dlls.

Upload the CBS log file from the CBS.log file is located in the C:\Windows\Logs\CBS directory.

I forget to say that reboot your computer after re-registring DLL files.

Update:
1) The repair install perhaps failed because i had a bootable USB stick connected.
Perhaps sometime it does reboot to continue.
2) The "optional features" are all gone , empty window :

When you are executing DISM.exe /Online /Cleanup-image /Restorehealth command, make sure your computer have internet access.

Please execute the following command and post the command output result.

Code:

dir C:\windows\WinSxS\amd64_microsoft-windows-servicingstack_31bf3856ad364e35_10.0.22621.3447_none_e948831242de6298\wcp.dll

I made a mistake by not telling you o run the last batch script with admin right from right-click context menu of the script, select Run as an Administrator.

FreeBooter · Apr 18, 2024

Open the command prompt with admin rights and execute the following command and reboot your system.

Code:

regsvr32 /s C:\windows\WinSxS\amd64_microsoft-windows-servicingstack_31bf3856ad364e35_10.0.22621.3447_none_e948831242de6298\wcp.dll

No changes , a flashing window. Note i have tweak the permissions , and all run as admin.
There is no other user at my system.

Update : i think also system's variables dont work.

FreeBooter · Apr 18, 2024

The command not using variables, what give you idea that system variables not working?

Open the command prompt with admin rights and execute the bellow commands one ata time.

Code:

Cd C:\Windows\System32

for %1 in (*.dll) do regsvr32 /s %1

Reboot your system.

but when i click the setup file nothing happens.
