MS has updated the compression again in 11_24H2 (UpdateCompression.dll -> msdelta.dll). Still. Although I can reach the Windows binaries inside the KB, I can't decrypt them from PA31 format. PSFExtractor needs to be updated IMHO. Try to get inside KB5058411.
We definitelly need the win32 arm32 port of Midnight Commander. The sweet thingy has two panels + ftp client. Since we still don't have ftp capable two panel file manager for arm32, it is the last thing we lack in Windows 8-1 RT arm32. For any coding wizard I am able to make a nice donation to let it happen. Message me about it or reply here.
