Hi Leo,
I had purchased an HP ROK license key of Windows Server 2022 Essentials and for some reason it isn't going through. It just keeps saying that the product key entered doesn't work. I double, triple checked the product key and its correct. I have an official HP ROK COA label but the Windows Server 2022 Standard evaluation copy that I'm using isn't accepting it. The following link on the bottom is where I got my copy of WS2022 Essentials. Do you have any ideas as to why? Is there a Microsoft phone number that I can call for help?

EDIT: Since I have an "HPE ProLiant MicroServer Gen10 Plus v2" (which has NO CD Rom drive), is it legal to rip my copy of the HPE ROK Windows Server 2022 Essentials CD into a bootable USB for me to install onto my server. HPE Support recommended that I format the CD into an ISO file from the external DVD and install the OS on the server. Again, my server does NOT have a cd rom on it which makes it difficult to install in an OS without creating a bootable USB Stick or creating an ISO file
