That's not the only problem. That's just a "for instance".
Another is that almost every application has to be installed running it as an administrator or it causes problems. That means for simple apps off the net you have to D/L them to the HD before you can install them rather than just running them. Furthermore, some apps will cause problems if installed to the programs folder (I thought Win7 fixed that but I guess not) and a lot of apps still aren't compatible with Win7.
XP simply doesn't have any of these issues and I can't imagine why you'd want to purposefully increase your frustration level with your OS.
Maybe one day MS will get this stuff sorted out but Win7 is no improvement over Vista. I guess I'll wait to see what they do with Mojavi
