There is no reg entry. There is file 'WinSCP2 (upload using SCP).lnk' in SendTo subdirectory of user profile. Unfortunately there is no 'SendTo' directory for 'All users', so you need to copy file to each and every user profile.
I've installed Winscp on w2k as admin. Explorer extension (send to) only avaible in this profil. I want it to be in ordinary userprofiles, too.
Maybe you can tell me the neccessary reg-entry to make. thanks
