With a Netop Host running on legacy Microsoft operating systems like Windows XP it was possible for the Guest to remain connected to the the Host during the log off and logon process. Due security changes implemented by Microsoft in the architecture of their next generation of operating systems like Vista, Windows 7, Window 8(.1), Windows 10, Server 2008, 2012, 2016 etc., Windows handles user sessions differently. It is necessary for the Netop Host application to unload and reload itself into the correct session when Log Off or Switch User is used either locally or during a remote control session. The configuration setting for auto logon resides in the Windows registry.
Due to the risks associated with editing the Windows registry, this style of work-around should only be performed by your Windows system administrator and should be thoroughly tested in a lab environment before applying the technique to a production computer. Your Windows system administrator could write two Windows scripts that are designed to modify the registry key forceautologon located in HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon. When this key is set to 1, Windows will automatically logon with the designated account after a user logs off. When it is set to 0, Windows does not automatically logon following a log off. The first script should be designed to disable the auto logon by modifying the forceautologon to equal 0. The second script should be designed to enable auto logon by modifying the forceautologon to equal 1. Then when a Guest user first connects to a Host, he/she could execute the script that disables the auto log on. After the next log off the Host computer will be waiting at the log on screen allowing the Guest to logon as administrator. Then that computer should be configured to automatically run the second script, that re-enables the auto log, on as soon as a user logs on to Windows. This enable script could be configured to run automatically as a log on script each time any user logs on. This would ensure that each time an someone logs in to Windows the entry for forceautologon is always returned to the "enabled" setting. Example 1: disable force auto logon
REG ADD "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" /v ForceAutoLogon /t REG_SZ /d 0 /f Example 2: enable force auto logon
REG ADD "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" /v ForceAutoLogon /t REG_SZ /d 1 /f
