As far as I know, Version 1809 of Windows 10 was the last version that worked for my EMU1212M sound card and EmulatorX3. Both of these are fairly expensive to replace. I have both of them working in Version 1809 right now; unfortunately, my Windows 10 1809 has become corrupted and the Microsoft store and Windows Update no longer work.
Is there somewhere I can legally get Version 1809 of Windows 10? I got Windows 10 for free many years ago after upgrading from XP (Paid big Bucks) to Win 7 (Paid Big Bucks) to Win 8 (Was pretty cheap) and finally Win 10 (which was free for me).
I don't see an install.ESD file in the $WINDOWS.~BT folder on my 1809 instance:
NOTE: I also have Emulator X3 and my 1212M working in a test copy of Windows 7 right now; unfortunately, I'm afraid if I upgrade that working Windows instance, I will be forced to select a version later than 1809 that will not support my EMU1212M. I do have valid Win XP, Win 7 and Win 8 license keys but they were all used to upgrade to Windows 10 so I don't THINK I am technically allowed to use them for an extended length of time unless I perform a permanent downgrade. I did not get a Windows 10 license key. I got Win 10 through a free upgrade offer and it is tied to my Windows Live email account.
