Explorer 100% utilization in Windows XP

Thanks to prozak for posting this in BPN on our forums.

    This from NTBugtraq: I have found a problem in Windows XP in that right clicking on a file in Windows Explorer causes 100% CPU utilization on Windows XP. This only happens on files that have not been selected first with a left mouse click. This problem is reproducible on Pentium 3 and Pentium 4 machines of varying speed, does not happen on Pentium 2 systems.

    I have been in dialog with MS regarding this issue and the QFE Team has denied fixing this issue since it will cause too many changes to critical code path . The workaround Microsoft has provided me said to Left Click on the file first before Right Clicking on it and bringing up the Right Click dialog box. If I have Single Click enabled in Windows Explorer I am not sure how I am supposed to follow the provided workaround since a Left Click on the file will cause the associated application to open the file. They are in the process of working up a KB article to detail this issue.

Although on Bugtraq a better workaround has been posted: Go to: Control Panel >
Display > Appearance Tab > Effects Button and *disable* (uncheck) the transition effects.... Credits to Lex Croes who found this workaround!

Screenshot: Right click select causes 100% CPU load and left click then right click @ 0% CPU load
