I recently bought an HP ENVY h8-1417c Desktop PC (SN:XXXX PN: H3Z18AA) which, unfortunately came with win8. I spent 3 months with win8, and after spending this "fair evaluation time" I concluded that I HATE win8. So I decided to get my new PC to run win7 pro 64bit. I bought win7 pro 64 after my evaluation period with win8.
I contacted HP to get some help "upgrading" to win7 pro 64bit (that's right, UPGRADING). Specifically, win8 is not compatible with LabVIEW. As an electrical engineer, LabVIEW is one of my main tools for my job. I discovered that my many other applications (Altium, ADS, etc.) were unstable with win8.
To summarize, HP online chat (2 sessions) were of NO HELP at all. Furthermore, HP's website was NO HELP at all with finding the many win7 pro drivers I needed to get for this machine. The entire experience made me feel I was being coerced into using win8 (by whom ? - one may ask). This actually made my defiance and conviction even stronger.
In conclusion: After many hours of "puzzle-working", I, ALONE, got my machine running flawlessly with my win7 pro 64 OS with NO CREDIT TO HP, or HP's online chat (chat: they don't even know English well at all). HP & Microsoft can count on me spreading this wonderful story around using any communication channel to which I have access.
If you, dear reader, would like some help muddling through a similar situation, ask nicely.
All you needed to do was to cross reference the motherboard and find a similar model with W7 64 bit drivers such as this one.
I chose this specific model because it even has the same video card as the one yours has.
Took me all of about 5 minutes.
Also, HP does not provide support for previous operating systems for their consumer based PC's.
Like it or not, W8 is the current operating system as of October 26, 2012.
While that may not be general knowledge to most folks, that has been HP's policy for years.
