Try doing the 'Safe Mode' transformation process Sin. I found that i had a heap of f*k ups with Vista Transformation Pack (even v11, the newest one) but i recently reinstalled windows and everything went fine
Anyway, here is the Vista Tranformation Pack on my PC at it's prime

. I personally don't use the sidebar or Glass2k (easily enabled/disabled); too useless for me.
I love Windows modding

I have hacked my own copy of Windows XP (completely legal) to have the Tranformation pack preinstalled (as well as a whole lot of extra tweaks and programs, and unneccesary services removed); and all references to the text "Windows XP" is changed to "Windows XP - Anarchy Warez Vista Edition" (except for registry and internals and the such for compatibility reasons). Note that Anarchy Warez is ME (you might see some RARE..... 'material' deep on the web produced by myself

. But ssshhh on that 1.....
FOR ALL U SCROOGES OUT THERE - This hacking of my Windows XP is a completely personal project, is not reverse engineered in any way and COMPLETELY COMPLIES TO THE END-USER LICENCE AGREEMENT and copyright/plagarism laws (for Australia anyway) as it is a NON-PUBLIC/PERSONAL PROJECT so DON'T BOTHER TRYING TO REPORT ME AS IT HAS ALREADY BEEN TRIED!!!
