I have installed Windows 10 Mobile Build 10581 on 3 Lumias. Everytime I try to open the tab AIDA64 / WINDOWS to get the information, which version of Windows is installed, the app crashes on the Lumias 735 LTE and 1020. Only on the Lumia 820 the app shows the information. I hope, that this problem will be solved very soon. As a registered user of AIDA64 Extreme, I can say, that I like the program.
