I noticed on my clean install of windows 10 that it no longer had an option to open my memory card/camera with Lightroom (both PC and Laptop)
I found an old fix that carries over to windows 10, a simple registry entry.
Rather than attach a file I will post the code, just copy and paste into a text file and save as lightroom.reg
Code:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Adobe.AdobeLightroom64]
[HKEY_CLASSES_ROOT\Adobe.AdobeLightroom64\shell]
[HKEY_CLASSES_ROOT\Adobe.AdobeLightroom64\shell\open]
[HKEY_CLASSES_ROOT\Adobe.AdobeLightroom64\shell\open\command]
@="C:\\Program Files\\Adobe\\Adobe Lightroom\\lightroom.exe \"%L\""
