Last prerelease Windows 10 tweak triggers crashes for some testers

An updated dubbed KB3074681 pushed to the current Windows 10 build for members of the Windows Insider Program is triggering crashes for some users. Rolled out on Saturday, the update causes a crash if you try to uninstall a program using Control Panel instead of using the more modern Settings screen.

The presence of a bug at this late date, especially one caused by an update, is disconcerting but not totally unexpected. Microsoft has been looking at Windows 10 as a work in progress.
