    Thanks!

    I'll fix it.

    As for 22621, it's best to take it easy... Everything can be adjusted with small steps.

    Cheers

    We are very happy that everything is great with you. But we would also like to be happy in our reality, in the 24H2 version. How can we use this knowledge base for our purposes?

    The new update of the 24H2 is totally different , it can be done but takes more time to modify first 1742 and the one you update , before the new update replace the old one and it was easy to modify the mum files updating only what you want.

    I manage to do same for 22621 cause it still has the same layout of updating the mum (and manage the same procedure with 678 packages in services ...which is wow and fast ..) but i give up because of the User Choice Protection (my a....) which changes all the modification you would like to make to registry , applications , pdf and even to add your favorite browser .

    i will not continue with windows 11 cause i do not find it yet ready for day to day operation specially when i am going away with my job 6 months , it is hard to fix problems .

    Maybe latter when i will have time i will play again ... but not for a while ...

    Basically with the scripts published by @balanadi in this link:

    https://forums.mydigitallife.net/th...ic-legacy-windows.86552/page-147#post-1880784

    The script uses the modified W10UI, so it pauses after extracting the files and before starting the integration, so that you can replace the modified .mum files in the folder where the LCU was extracted.

    In my test, using only Windows 10, with a custom script for my exclusive use, everything works fine, without errors.

    I am adapting the SD10_Renewed script for this method.

    Let's see if it works as expected.

    which test can I do? with what script version?

    I am eager to see if new change works on SD10, in size, in functionality.


    Thanks,

    I am glad that i give a reason for people to start modifying the mum files , as in my opinion is the easiest way to debloat as you follow microsoft way but delete from the mum what it does not make you happy ..
    As a basic information , màke sure you ðo not remove the basic packages included in each edition ...
    I will be back after 10 days from my cruise in the morning and hope i will find more people bringing some input and specially to find a way for 24H2 after you remove user choice the Store it does not update anymore ..it works but the downloads are blocket by this new clever (stupid in my opinion) decision from Microsoft that they want to force you update only ussing theyr stupid update ..
    Have a nice weekend and hope to hear good news soon

    I'm finishing the tests with SD10_Renewed.

    With pt-br_windows_10_enterprise_ltsc_2021_x64_dvd_f318268e.iso everything went well, in the Slim option.

    Now I'm going to test in default mode, to see what happens.

    Then I'll test with:

    - 19045.1826.220708-0121.22H2_RELEASE_SVC_REFRESH_CLIENTBUSINESS_VOL_X64FRE_PT-BR.ISO

    - en-us_windows_10_iot_enterprise_ltsc_2021_x64_dvd_257ad90f.iso

    As long as everything goes well, I'll make the new script available.

    Please wait...

    @sainfo can you advise what needs to be altered in this script to retain the normal windows search in the taskbar?

    Update: I removed all related reg files for the regular search on the taskbar from the personal & tweak dir, though still not showing?
