Windows 10: One Windows 10 or 11 OS Key Serial Number for Multiple installs on same Partitioned PC

HelloWe run Automotive dealer level software. Sometime these software are made by the same company and you cannot install them into the same OS. They will corrupt each other. Ford and Mazda are good examples. We are trying to avoid having to use multiple pc's all the time. One PC per tech.The simple solution is to partition the hard drive and run multiple boot OS system and keep them separated, but booting into a OS for each.Can you install OS multiple time on the same PC with no physical hardware changes, with the same Key serial # OS?Appreciate the clarity on this.We have about 12 com

Fresh Install of Win 10 without Serial Key?

Microsoft Windows KMS client install keys work well fie these situations and test lab situations as well:

Appendix A: KMS Client Setup Keys

That will let you install a Windows OS legitimately with a Microsoft provided install key.

They will not activate the OS, an activation key would be needed for.

Installing Windows 10 using Windows 7 key

Two quick ways to use your Windows 7 key during the install:

1. When asked for the serial #, put in that Windows 7 serial # and continue on. It should activate as soon as it hits an internet connection.

2. When asked for the serial #, at bottom of window click on the I don't have a serial # text (or whatever it says). It will then ask what version you want to install, ie. Home or Pro. Be sure to install the right version that matches your Windows 7 key. Then once you get into windows you can activate by putting in the key. Some people prefer this method, not sure why honestly. Easier to do #1, since the installer will see your key and know which flavor of Windows 10 you are trying to install.
