Hi, i just wanted to inform you that on latest Windows 19041, when KB4556803 get downloaded it causes system to crash. I didn't understand why, it happend also after a clean install. Then i've seen it was aksfridge.sys. I don't know why the file was on my pc. I suppose installed by ZEISS Zen 3.0 (lite), i don't even use a dongle with it but the driver is there anyway. I had to revert the install of the update and then Changing HKLM\System\CurrentControlSet\Services\aksfridge start value to 4 the problem does not occur anymore.
The Aksfridge.sys version i have is 1.78.12384.
