Because it's primarily a help forum, I'm reluctant to say this on the Ubuntu forums, but I have no hesitancy to say it here...

If you do not like Ubuntu, use Windows. Linux is not for everyone. No apologies or rants are necessary to justify moving back to Microsoft, nor is there any reason to knock yourself out over an OS that you apparently lose sleep over.

As long as you keep it secure, Windows is a fine operating system, that's very user friendly for both common and complex tasks.
