What were you trying to do that didn't work?
I did some sanity tests on the old windows version as below, win10-1903,32bit and 64bit hit the failure that some virtio drivers couldn't be updated by installer.
Windows 10, version 1903 - fail
Windows 11, version 21H2 - pass
Windows 11, version 22H2 - fail
Windows 11, version 23H2 - pass

Other info:

Trying to update from virtio-win-1.9.43-0.el9_5.iso to virtio-win-1.9.44-0.el10.iso in the same host and OS, didn't hit it. So setting it to a regression issue.
