Just to add my 2 bits on my Windows 10 upgrade....

I updated the machine I run my AC 8.2.2 client on. I didn't touch my peer to peer "server" which is running Win 7 Pro. Immediately, I noticed a huge slowdown in performance on the client whereas previously, there were no real issues with response time. Patient charts are taking 20 seconds or so to load and close just on the Windows 10 machine. Tried a number of things to improve the performance with little luck. Just as an aside, a strange issue presented itself when I tried to run AC as administrator. I made the change in the program properties and it then couldn't find any mapped network drive. I changed it back and it worked fine again. I have never seen that happen before under Win 7.
