Features of WIndows that are bad

List one feature, aspect, or thing that you think is bad about the design of Windows itself (rather than the performance or design of supporting applications).  Also state why.  Try not to list something someone else has already listed.

No OS wars, please.  Do not mention any other operating systems.

I'll begin with an easy one.

Http.sys - Because kernel-mode HTTP servers are just kooky.

There's a hidden secret "no to all" option, you have to hold shift when clicking [non].  Or maybe right click when clicking [no].  I don't know, I haven't used windows in ages.  But you're right, the option should be clear in the dialog box.
