DISM and SFC say "Class Not Found" Windows Server 2022

So, I doubt this is the right place to ask for assistance, but I have been searching for someone else experiencing the same error messages as me and I have only found it on this forum.

We rolled back the server from a failed windows update and had to re-register a new EFI boot record to get the thing working again. It was a long day.

Currently when running updates, they fail, when running dism it returns the error "Class Not Found". The CBS Logs point to "CbsSessionOptionRepairStoreCorruption". I have tried many things to get the class registered again in registry editor, but alas I have failed. I can attach CBS and DISM Logs as well as a capture from ProcessExplorer to help with tracking down the issue. I just don't know of a way to repair the Servicing Stack or the Repair Store in windows. I've never needed to do it before.

Things that did not work:

• In-Place Upgrade, the upgrade failed and it rolled back to the version in the post
• All Dism and SFC and SFCFix commands return "Class Not Found"
• Windows Update is broken too
• Using Regsvr32 and /register to register the applications in the winsxs folder, system32, syswow32, and the ServicingStack folder resulted in no changes

Any help would be appreciated. I'll add files if requested. If this is not the right place to ask for help. I'm sorry I didn't read the rules well enough.

Hi there, welcome here.

This may seem like a strange litte app but it’s proven sucessful for people I have talked to whom have had problems with Windows Update and the registering of system files (which could be an issue?)

It’s worth giving a try. It is a portable app so you can run it from a USB if you like.

Windows Repair can perform the following tasks:

• Reset Registry Permissions
• Reset File Permissions
• Register System Files
• Repair WMI
• Repair Windows Firewall
• Repair Internet Explorer
• Repair MDAC & MS Jet
• Repair Hosts File
• Remove Policies Set By Infections
• Repair Icons
• Repair Winsock & DNS Cache
• Remove Temp Files
• Repair Proxy Settings
• Unhide Non System Files
• Repair Windows Updates
• Repair CD/DVD Missing/Not Working

The only thing I am not certain of, is if it works with Windows Server. I can’t see why it wouldn’t.
As always, I recommend you create a system image before adjusting system files.
