So, I am trying to apply latest windows 10 update to WinPE, following instructions here: https://learn.microsoft.com/en-us/w...iew=windows-11#add-updates-to-winpe-if-needed

What I am stuck on is when I go to the link provided to download the update, https://www.catalog.update.microsoft.com/Search.aspx?q=cumulative update for Windows 10

Any update I download is a .cab file, not a .msu file as specified in the instructions. If I try to run the command with the CAB file as the target file, it fails and says "The specified package is not applicable to this image."

What am I doing wrong?

Note: my end goal is creating a bootable PE media on a usb, so I can boot to that and switch my HD from MBR to GPT without losing my current PCs windows installation and data.

1. There is the MBR2GPT tool.
https://learn.microsoft.com/en-us/windows/deployment/mbr-to-gpt

2. "without losing"....ANY change like this needs to be preceded with a known good backup. Full drive, or just the things you do not wish to lose.

Yeah, I plan on creating a full disk image before trying this. That way if it TOTALLY tanks, I should be able to just wipe the disk and then restore it with the image. (I use Macrim(sp) Reflect).
 
as mentioned above, mbr2gpt from windows recovery/windows boot media will just do fine

as for winpe, you can use hiren boot which is win pe + bunch of recovery tools

Maybe I am overcomplicating this. I thought that the mbr2gpt tool had to be run from WinPE, which is why I was messing with this in the first place. Are you guys saying I can just do this: https://support.microsoft.com/en-us...a-8766-73fab304c246#WindowsVersion=Windows_10

and it will work just as well?
 
You can run mbr2gpt from within windows.
You can run it from command prompt, when booted from windows installation media (press shift+F10 to open command prompt).

Ok, when I read the instructions for doing that, it said that if I do so using the /allowFullOS command, "Since the existing MBR system partition is in use while running the full Windows environment, it can't be reused. In this case, a new EFI system partition is created by shrinking the OS partition."

I'm not really sure of the implications of that or how much space I'll lose on disk, so I was trying to just avoid it by running it from a bootable USB.
