Watch how to configure the speech recognition wizard on Windows 7


Choose the same options in your language (every time you log in, until we find a way to set these options on a per-machine level).

More disruptive recommendations to downgrade to colorscheme basic on lab PCs despite Themeswitcher?

  1. Is this maybe what happens when Themeswitcher crashes: While the desktop background still gets changed, the Colorscheme does not get set to Basic? How to avoid the crashing FileIOException? What fileIO may a colorscheme change require?
  2. image
  3. image
  4. Disruption is the least of the problem: The warning comes up when computers become dangerously slow. In the past, they have become disfunctional during these episodues and needed to be power-cycled. This has resulted in loss of assignment and assessment materials.

"Server busy" error from Windows 7 speech recognition?

  1. Problem: We see this error frequently, on various LRC PCs, when logging in. clip_image001
  2. Root cause: It looks like this is a speech recognition related error on the LRC PCs. Now that I am testing speech recognition on my office PC, I am seeing this error there also when starting speech recognition (together with a slowdown – not sure what is cause and effect there).
  3. clip_image002
  4. Workaround: Not auto starting Windows 7 speech recognition, but having users launch it form the desktop when needed, should alleviate this problem.
  5. Resolution: Still investigating.

Input languages missing on PC21 to PC31

  1. I only had a chance to check the PC’s in the title.
  2. This is the size of a good language bar: CAM05715
  3. These PCs are missing input languages when I am logged in:
  4. CAM05714CAM05709CAM05716CAM05717CAM05720
  5. my phone has a poor camera, so this needs double checking:
    1. looks like pc29: CAM05719
    2. unclear which, but appears to be in 2nd row: CAM05708

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?

Getting rid of “You must restart your computer to apply these changes”

CAM05590

I am seeing this on several computers when I or students log in. To make matters worse, “Restart now” is the default selected button, and the computers are deepfrozen, which will not only lead to loss of (potentially valuable face-to-face class) time, but could even result in an infinite loop if we do not get rid of this message.
