Cluelessness at Microsoft (Score 5, Informative)

There's a reason why most people don't use it. Microsoft's implementation is flawed to say the least. When a user sets themselves up this way and then installs programs as an Administrator, they find that they can't run the programs completely or correctly as the lower privilege user. Some of this is due to Windows application programmers doing boneheaded things. Much of it has to do with the programming practices Microsoft has fostered - like writing to global registry keys in the Windows 95 and 98 days. Contrast this will Apple which has gotten the APIs right, put out tutorials on how to do this and most importantly made the whole process of installing as Administrator but running as a User as painless as possible.
