Prevent multiple user login to avoid “Another instance of Tutor is already running in another user’s session on this computer” by disabling fast user switching

  1. Problem: As reported earlier (in the Spring and in the Fall term),  for the student PCs, Sanako issues (but likely also general performance problems, and reportedly problems on classroom computers outside of the LRC) caused by multiple users being logged into the same PC – not limited to logging in from remote via MSTSC -  seem on the increase this term (this year?), also on the teacher PC, where they prevent the digital audio lab from starting:image
  2. Workaround: force restart of the computer (time-consuming, though).
  3. Solution: Avoid, better prevent multiple user login, maybe by disabling fast user switching?
    1. Registry: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System\HideFastUserSwitching =1, or
    2. Group policy: Computer Configuration\Policies\Administrative Templates\System\Logon\Hide Entry points=Enabled.
  4. Other considerations:
    1. Side effects: unclear?
    2. Root cause: Not enough data. Why do users remain logged in in the first place?

“Back to basics”: Need once again to default to color scheme basic on teacher computer

  1. Same problem as last term: (What made it come unstuck/unfixed?): CAM04573
  2. CAM04574
  3. No Sanako screen sharing activity involved here, but MS-Community-Clips screen sharing.
  4. Classes are moving in, and we cannot have the teacher computer slow to a crawl and eventually crash in the middle of a Sanako class, especially not when an assessment is involved.

Forced downgrade to Color scheme Windows 7 Basic since “exceeded its allowed memory”



  1. clip_image001
  2. This warning and forced downgrade appeared on the teacher after starting using MS-Community Clips (which is just a GUI wrapper for Windows Media Encoder internally, which we used on the same machine successfully while it was still on XP).
  3. The error seems slightly more informative than what we received earlier, but I did not manage to investigate since this was in the middle of supporting a teaching use .

How to move an invisible window back onto the screen in Windows

  1. Normally you would drag the window by its title bar into its position with the mouse – but if the window is off the screen, the mouse cannot access it.
  2. Here is how to use the keyboard arrow-keys to do the same, after right-clicking the window’s task bar icon:

  4. This example is with our Sanako student (a bug or misconfiguration we are investigating), but works with most windows on most versions of MS-Windows.
