Yes, there’s a new desktop window manager, but no, I don’t know any more about it than you do


Sean W. requests, via the suggestion box, "an in-depth discussion of the use of the shell's new Desktop Window Manager (Dwm*) functions in Win32."

The desktop window manager is not actually part of the shell. It operates at the window manager level. (Notice that DWM is active even when Explorer isn't running.) You probably should have posted your suggestion to Greg Schechter's request for DWM topics which was not too old at the time you posted your topic suggestion. But then again, "Best practices for applications under the DWM" was on his list of future topics, so it looks like what you wanted was already on his to-do list. I don't know whether he followed up on his own to-do list, though. If not, you can always consult the Performance Considerations and Best Practices (for using DWM) topic in MSDN.

    Anyone know if Greg Schechter is still working on DWM, or if there’s a better person/place to direct DWM-related questions/feedback to these days?

    I found a bug in the DWM Thumbnail API that crashes DWM.exe when you alt-tab, if you aren’t careful how you use the API, but not sure where to send it.

    (Also have a question about whether it’s possible to detect when DWM is doing the window-open animation for a window.)

    Have been playing around with the DWM API recently and it’s let me do some neat stuff.

    With Intel graphics drivers, switching the Windows 7 Magnifier to Docked mode makes DWM crash and not restart the service.

  3. curmudgeon says:

    Does this look like the appropriate place to log a bug?

  4. cmdlet says:

    No obviously it is not but AFAIK the bug tracking system for Windows isn’t public and bugs reported on forums and newsgroups hardly ever get fixed.

  5. No obviously it is not but AFAIK the bug tracking system for Windows isn’t public and bugs reported on forums and newsgroups hardly ever get fixed.

    And that’s a flawless argument for posting it here, where it’s guaranteed to get fixed…

    Of course MS can’t have a public bugtracking system, that’s like admitting, err, that they have bugs.

  7. someone else says:

    As the monthly updates show, MS is well aware of bugs in there products. A public bugtracker, on the other hand, requires a certain savviness on part of the submitter, for not everything that looks like a bug *is* a bug. If MS created a public bugtracker, they would be *swamped* in bogus and duplicate bug reports.
