Recently, Adobe Reader DC have started to always opening documents in maximized windows covering the entire desktop.

How can I turn it off?

This appears to be fixable only by changing the irandom registry entry to 0x1000.

Set the registry key https://forums.adobe.com/message/8149543#8149543/irandom to hex 0x00001000 (decimal 4096), as described here in 2015.

For Acrobat DC (not Reader), there is a different key to make it remember the last window size/placement:

HKCU\Software\Adobe\Adobe Acrobt\DC\ExitSection, change bLastExitNormal from 1 to 0
