Because the current OS is W10 Enterprise, there is a little ambiguity as to whether there will a problem. My question relates to being uncertain as to whether I can perform an “in place” upgrade which will preserve my files and apps, or whether, I will be required to perform a total clean install and totally rebuild the system.

I would use the paid activation key to do an in place upgrade to W10. I think (am considering) purchasing a W10 Pro OEM Product key and using the MS Media Creation Tool to download W10 Pro ISO from MS. The enterprise version of the OS was installed by the system builder and I do no have access to the MS volume licensing program and so I have no path forward to W10 Enterprise. As I look ahead to January 2023 end of security support for the current OS, I am thinking whether I should try to extend the life of the system by a few years by upgrading to Windows 10 Pro OS. I have a i7 4770K Haswell system that is about seven years old running windows 8.1 圆4 Enterprise OS.

Windows 8.1 update to windows 10
