Here you are - start with the Hercules emualtor and follow these lonks -yes it really works on Windows (and Linux) too. (For those who want to try running an older IBM Mainframe OS on a PC -yes it can be done surprisingly easily !!) If you want to install an app that isnt available in the Microsoft Store, or if you have Windows 10 Pro, Enterprise, or Education and want to upgrade to Windows 11, youll need to permanently switch out of S mode. If A simple windows upgrade is taking that long -something mega wrong somewhere. To increase security and performance, Windows 11 in S mode runs only apps from the Microsoft Store. I remember when doing a complete full 'SYSGEN' on some old IBM Mainframe systems - circa mid 1980's - MVS / SP for example never took more than a couple of hours -and that was on hardware today that even a lowish laptop would run rings round (For old timers - some of the hardware was on old IBM 3031 / 3033 equivalent boxes).Īlso a lot of modules on that 'Sysgen' would have to be compiled 'in line' from source - using the IBM built in Assembler and actually a good 'Meta language 'they had at the time called PL/S -note NOT PL/1 which was quite a good language anyway. You can visit the Download Windows 10 page and follow the instructions to use the Media Creation Tool (MCT) to build installation media.
If that doesn't work, then you can start troubleshooting. That said, are you working from an online download or a local ISO file? If you're not using an ISO that might be your next best bet. You can let it run overnight if you're patient, just to make SURE it's not going to finish on its own. You're right: it shouldn't take that long.
