>The fix for Windows 8 (and I am pretty sure should work in Windows 10 but I do not have time for testing it) is to edit the registry key HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Policies \ System and add a DWORD value named EnableLinkedConnections with a value of 1, after you reboot your computer you can enjoy your mapped drives in admin mode.

What other linked connections, apart from mapped drives, does this affect?

(and isn't "link" implied in, or identical to, a "connection"?)
