I am using OpenCore Legacy Patcher OCLP 2.4.1 running Sequoia 15.7.2 and UEFI Windows 11 23H2.
I installed Windows 11 in UEFI mode following this OCLP guide:


I wonder if I could upgrade to 25H2 just creating a Windows 11 Installation Media following the steps in this general guide:



I don´t want to break my beloved 15 y. old Mac Pro….!

Thank you in advance!

After some research I have taken the risk.
The guide worked perfectly well in my MacPro 5,1 so I have upgraded my original UEFI Windows 11 23H2 to the latest 25H2 without doing a fresh installation. That process has been very straight and all files and drivers were kept in place. Windows 25H2 runs perfectly well.

"Windows Update" just was updating inside the original 2023 installation (23H2) because MacPro is an unsupported device. In two years, I had missed 24H2 and 25H2 versions.

I hope this can be useful for someone
