I am running Windows7 RC1, I have recently installed CheckPoint VPN SecureClient (http://www.checkpoint.com/products/vpn-1_clients/) to connect to my work network. On installation this appears to have disabled Fast User Switching. You will notice "Switch user" is now greyed out. I tried some googleing first and the most popular solution is to remove a registry entry at HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon \ GinaDLL I have no entry there. Any ideas? Thanks.
