There is some very good code in windows 8, and honestly would have been the best OS Microsoft has released to date, with the exception of cramming the Metro UI down our throats. I kind of like the normal elements of it. but the tile tabled/phone UI elements being shoved onto my desktop. Well that is the most cumbersome PITA i have dealt with from MS. I would rather be back running Windows 98 with all its weirdness and stability issues. I have discovered that I am not alone in this, and the following links will help you ease the rage and pain that Metro will cause you.
First Option:
this is a bit of a manual process, but i have used it and it works well.
http://lee-soft.com/vistart/ - Be very very careful when you install this. it comes with allot of adware, nothing malicious but you might end up with programs you do not want. (you get agree/disagree options for other programs before vistart is set up)
http://betanews.com/2012/06/21/you-can-hack-windows-8-metro/ - how to sidestep the metro tiled interface being the first thing you see. it will 90% of the time take you directly to your desktop sometimes it will delay depending on what your computer is doing on launch in the background.
http://technet.microsoft.com/en-us/library/cc721931.aspx - Start Task scheduler in Win8, its not as obvious in metro.
Second Option:
Well I have not yet found one that still worked. Will update this if i find it.
