I have not yet used WinPE 11, but WinPE 10 1709, because none of my systems run Win11 yet and most of them still are MBR systems. However I just found out that my WinPE 10 v1709 rescue CD/boot item does not recognize the storage space on my Win10 x64 21H2 MBR system. From this post I understand that may have something to do with the WinPE version of the rescue environment. So I figured I would maybe try WinPE 11 instead (which I have not done yet at the time of posting this). To my surprise, when I downloaded WinPE 11 using the download manager I saw that there are still 2 versions available, x86 and x64. I do not understand the WinPE 11 x86 version, as Win11 is x64 only. Does anybody know how this is possible?

Also, does a Macrium WinPE 11 rescue medium still support MBR systems? As Win11 is UEFI only, I always thought that is not possible. But apparently Macrium also has an x86 version of WinPE 11, therefore I am not so certain anymore.

I know that for solving not seeing the storage space I could probably also use WinRE, which is more recent than WinPE 10 1709. Up until now I have chosen to always use WinPE 10 1709 on my rescue CD and for the boot menus, to keep them all equal and also to have rescue media independent from a specific computer (a.o. it can be made on my Win7 system, which is still my main system). I have prepared a small set of necessary extra drivers for WinPE 10 1709 that work on all of my systems, by manually including them in the drivers folder. This rescue CD works on all my systems (running Win7 (ESU) and Win10 respectively), which is really handy. If possible I would prefer to keep that approach the same, i.e. using the same WinPE version across rescue media and boot menus.
