Slimdown10 – turn Windows 10 22H2 or LTSC 2021 into classic/legacy Windows

You need Microsoft-Windows-Client-LanguagePack-Package-amd64-ru-ru.esd in your casee from UUP files when you download 10.0.26100.1_ru-ru and you exract in lp folder deleting the en-us

 

Got it, thank you very much! Of course I could have guessed about "lp" myself, but it only occurred to me after your hint...

@balanadi
I tested your script without an error ran in a vm worked very well for mine! I will customize to remove store and do more testing, thank you for your script.

 

I found this one in a 26100 pro to LTSC reconstruction ...

Code:

<?xml version="1.0" encoding="utf-8"?>
<unattend xmlns="urn:schemas-microsoft-com:unattend">
    <servicing>
        <package action="stage">
            <assemblyIdentity name="Microsoft-Windows-ProfessionalEdition" version="10.0.26100.1" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" />
        </package>
        <package action="install">
            <assemblyIdentity name="Microsoft-Windows-EnterpriseSEdition" version="10.0.26100.1" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" />
            <source location="Microsoft-Windows-EnterpriseSEdition~31bf3856ad364e35~amd64~~10.0.26100.1.mum" />
        </package>
        <package action="remove">
            <assemblyIdentity name="Microsoft-Windows-ProfessionalEdition" version="10.0.26100.1" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" />
        </package>
    </servicing>
</unattend>

 

to remove store just delete the folder Appx cause already is removing store before starting the reconstruction

 

I see, but in my case the task is different. I don't need to transform anything because I already use IoT Enterprise LTSC. Therefore I think that in my case file 1.xml should look something like this:

Spoiler

Code:

<?xml version="1.0" encoding="utf-8"?>
<unattend xmlns="urn:schemas-microsoft-com:unattend">
   <servicing>
       <package action="install">
           <assemblyIdentity name="Microsoft-Windows-IoTEnterpriseSEdition" version="10.0.26100.1" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" />
           <source location="Microsoft-Windows-IoTEnterpriseSEdition~31bf3856ad364e35~amd64~~10.0.26100.1.mum" />
       </package>
   </servicing>
</unattend>

I assumed that these actions would clear the WinSxS folder and replace its contents with the sxs package files. Which would significantly reduce the size of the WinSxS folder, but this did not happen, to my regret. Apparently, in my case, there is no need to do all this at all and just delete the sxs folder as unnecessary?

 

My question to you is : if you just install Microsoft-Windows-IoTEnterpriseSEdition without removing Core and Professional maybe that is the reason you have so many in winSxS folder ... there are 3 editions in your image now ...
