Hello everyone. I have a dc7900 SFF that came from the factory with Windows Vista, which included an OEM operating system badge from Microsoft for the same.
Not long after, I elected to take HP up on an offer to upgrade to Windows 7 for free via recovery DVDs they mailed to me.
I'd now like to upgrade to Windows 10. However, every time I try to upgrade using Microsoft's "Get Windows 10" tool, or GWX, the process fails with a "0xC1900208" error, which I now understand is an application compatibility error.
The following is what I've done so far.
1) Restored the machine to factory state using the Windows 7 Professional (64-bit) recovery media.
2) Uninstalled ALL applications via "Add/Remove Programs" in Control Panel.
3) Connected the machine to the internet in order to download the GWX tool.
4) NO Windows updates of any kind have been installed.
My question to the group is, could the reason the machine passes the hardware check, but fails the application check be that the original key for Windows was for Vista, for which there is no upgrade path to 10? If so, is there anything I can do? If not, should I fully update Windows 7, then upgrade to 10?
Thank you for reading this.
