python Windows install manager 26.1.msix, on Windows 11 ARM 25H2, downloaded from python.org.
Appears to install x86 Intel binaries?
(Whereas python-3.14.4-arm64.exe as expected installs ARM binaries.)

It would be nice if the install manager reported the platform and informs user what is about to be installed, and tell user if they really want ARM binaries to use the dedicated ARM install EXE, not the MSIX. There is no indication to the user that x86 will be installed.
