I'm not sure where your problem came from with the google play store. I downloaded the new version of AMIDuOS the night that you posted the release news. I installed it on my Surface 3 Pro running Windows 10. I did not have any of the issues that you mentioned. It installed without a hitch, I got logged into my google account and downloaded my apps without a single crash. So far, the only problem that I have run into was DuOS locked up on me after it was left running when windows decided to hibernate. This only happened once.
I'm wondering if it was happening because they were installing it on Windows 7, which is a 'hardly supported' OS at this point.
To the people on Windows 7: Time to update to Windows 10. No, there are no real security or privacy issues as long as you turn off Cortana.
