1. AFAIK specific keys work for specific manufacturers e.g. Dell keys for Dell machine, the same with certificates 1.5 because it seems to me you bought a machine with a generic kms key, they expire after 180 days if that machine cant connect to kms server (like in corporate environment) 2. you mean dvd , yeah you can clean install Windows 7 now (which i recommend), this is what you need for that en_windows_7_professional_with_sp1_x64_dvd_u_676939.iso thats the last iso of win 7 pro sp1 from microsoft 3. youll probably need a custom bios for that, there are threads on here for that, im sure good folks at MDL with help you
@molisz - Don't know how to thank you enough - and @ForrestGump, too. Would it be too much to ask if you have an Office iso? I'll research whether activation is possible on another thread.
Well, as you're feeling generous, why not the latest and greatest? 2019 Pro? Feel free to choose Student or Personal, if you think that's going too far.
@molisz - Oops. @ForestGump is just telling me that Office 2019 only works with Win10 (thanks for the warning). I can use that on another machine, but for Win 7, I guess I'll need 2016.
Ok, my enthusiasm is getting the better of me. Next, Office, BIOS mods for SLIC, and SLIC in SeaBios for KVM/QEMU installs! )
The partial key you posted was kms key for windows7 pro why dont you download Daz loader it will install correct dell key and certificate it will not install loader part if you have slic 2.1 in bios.
