To all you 7600U owners,
The Beaut AIO 7600U PC, was never supported by ACER for upgrade to Win 10 (Not on their list).
I have started this post so owners can get straight to the relevent info. without having to search through 1 years worth of posts
This PC it appears only ever had ONE! issue (incompatible with Win 10). The NVidia Graphic's Driver.
This was recently FIXED with the release of a Driver Update from NVidia. Released about 29/12/16 (I think). I receieved it about end of January 2017. About six months after the end of the free offer.
But I can attest to the fact, of only the one issue. As I managed to install Win 10 on my PC 25/7/16 (just before the end). I have been running Win 10 since. With the onboard Intel graphic's and NVidia Disabled. Never had any issues with the PC. It has had all Win 10 updates even the big ones. With no issues. Was just a shame to not have NVidia (but I was hoping and waiting).
Then they Fixed it.
So!
Those that managed to get Win 10 installed, running AND activated at MS (because my free copy did not auto activate after install, I had to phone them and they remotely did the activation. Don't know why). Should now have no problems reinstalling Win 10 if you not running already.
Those that did not get a free copy activated, you could try and contact MS appeal to their better nature and ask for a goodwill copy. For all the pain and suffering they caused with their free offer Win 10 App. That said your PC passed all the credentials, but would not install win 10. A cause of much lost time for many. Other than that I'm sure you know the only other options.
I just wanted to inform anyone who wants to know, that Win 10 does work well on this PC. I personaly am now perfectly happy with it.
Cheers!
PS Hope to add to this post later, with usefull info (I am out of time). Though it may not be required now with the NVIDIA Updated Driver
