Yeah, I meant in general your not going to see any improvements in applications. It's all purely around launching them.

Why is the MCT ISO .8653 and not .8655?

Beats me. In a YT video a reviewer also talks about this way to get your system to 26200.6855. But apparently it doesn't. The .ISO created by MCT is also leaner; 6,25Gb while the official v2 version is 7,76Gb. OK the official one let you choose Home/Pro etc. The MCT is fixed to the Windows version you already have. (While it also contains Home/Pro etc. Install let not you change that version) Amazingly the number of packages drops down from 174 down to 139.

Interrogating the install.esd before the new install also reveals the build version is also 8653;

What I find remarkable is that the number of 1742 base version drops also from 74 to 61. (In both updates the number of 1742 and the version build packages are the same.) During all updates of 25H2 that number was still the same. During new installs and In-Place-Installments. Despite a new install it does not partitions your disk but reuses it. At the end it also contains an windows.old directory with no other directory's then your C:\Users\<Username> Deleted this one because I already have a backup of the whole disk.

I did a clean install using the MCT created install USB yesterday, and it did indeed install 26200.8653.
As soon as I connected to Windows update it grabbed Security Update (KB5094126) (26200.8655).
Dism RestoreHealth still ran incredibly slow in the 60-70% range, otherwise all seems to be well.

peace

I also created a bootable flash drive using the MCT yesterday and it also grabbed .8653 and afterwards the June update was installed. It's a change of behavior since if the bootable flash drive was created Thursday after Patch Tuesday or after, it already included the update. This time at least the window that shows the system steps when installing is still there. You know, something like this: I've been performing monthly clean installs of Windows 11 since 25H2 came out and I know this very well.
- Bootable flash drive created before Patch Tuesday: When installing Windows the window shown above appears and downloads and installs the monthly update along with drivers and tells you the %, when the system is going to reboot etc.
- Bootable flash drive create the Thursday after Patch Tuesday: When installing Windows It already includes the monthly update and when you connect to the internet the window doesn't show up and you have to let the system grab the drivers. It could be on the window where you're prompted to name your device or on some other step along the way. The process runs in the background and you have no idea when it's finished - in my case I had to listen to my laptop fans to get a general idea when it was done...ridiculous

Problem is this time, like I said before, the June monthly update is still being downloaded and installed. And to make matters worse, some features are missing from my device. I've tried multiple clean installs and some features and settings are missing, like for example, lock screen widgets. There isn't even an option to enable/disable them. It's like they were removed from Windows. Maybe the code is there and it's going to be triggered in the future bla bla bla but what's the point? Prior to creating a flash drive on Friday, on Tuesday I took the same steps and it installed everything well. So basically I created a flash drive that should already have the update embedded and instead it also downloads it and installs it while at the same time installing a light version of Windows. How does this make any sense?
Not to mention the bug when deleting stuff. You delete a folder named ''A'' and the recycle bin asks you if you want to permanently delete a folder named '&4tyhgfuh'
Baffling stuff from MS once again. Why am I even surprised...
