One of my users got an annoying message when starting MS Paint (mspaint.exe):
Onvoldoende geheugen of bronnen om de bewerking te voltooien. Sluit enkele programma's af en probeer het opnieuw.
Insufficient memory to complete operation. Close some programs and try again
Other resources suggested that the file opened was too big or that we're doing something with a .tiff file. But he was just starting paint, no images involved at that point. The solution was to open regedit and remove the following key:
That reset all MS Paint settings and we could start paint again.
