I've never had the problems you describe.
I'm suspecting you lack the knowledge to make Windows behave the way you want it to. I'm very sorry, but that's not Windows's fault.
I too am certainly lacking in this Windows Knowledge because I can never get it to behave the way I want. If I do get it doing what I want it seems that it just changes itself back for mysterious reasons. On the other hand I find Linux very easy to make work exactly the way I want and it keeps working that same way seemingly forever. I'm no more knowledgeable of Linux than Windows. Maybe Linux is just easier to use.
If special knowledge is required maybe it's best not to hold out Windows as the easiest to use.
Where I'm coming from:
The clumsiest interface I have ever used is punch cards for input and 132 column tractor feed printer for output. I used DOS for many years. Win 3.1 Win 95, 98, XP. I don't have any real problems with Windows I just don't like it. I've been using Linux for ten years and have played with many of the various desktop managers. So I have used many different interfaces and operating systems. They all have their pros and cons.
Windows pros: It runs the software I need for work.
Windows cons: It's the only thing that runs the software I need for work.
KDE is hands down the most versatile and powerful desktop manager I have had the pleasure of using. I'm using Gnome lately and find it okay but limiting. The Beryl or Compiz effects are outstanding. Maybe the best 3D desktops going.
I recently was browsing the web on IE7 running on Vista and found it almost unusable. Mostly just unexpected, for me, behaviour from IE7. I probably would have been fine with FF.
While I don't like Windows I use it regularly and have few problems with it. Most serious stability problems have been hardware related. I do consider randomly changing things I didn't want changed to be a lack of stability. In that regard it is probably the least stable desktop OS available.
I need a new machine for the living room and just might buy a Mac. I hope to never need Vista but I wouldn't be surprised if I end up with one of those at some point.
Arguing about which OS is best is like arguing about who owns a better hammer when neither of you have the skills to build a house.
Whatever gets the job done. All the current desktop OS are pretty amazing really.
