Or you could do things like cleaning up and defragmenting, scanning for viruses and spyware, making sure you don't install junk software, checking the Event Log or the Device Manager or the Action Center for any problems...
Windows gives you a lot of tools to manage it, and it does a fine job keeping itself in good shape. But the user plays a role in it, too.
Instead of summarily blaming Microsoft for something that may well not even be their fault, why not tell us what exactly your issues are? It's understandable to be frustrated and have the need to vent, but we can only help you if you help us help you.
Or as GlaDOS from the Portal games would say:
Thank you for helping us help you help us all!
