Hi Welcome to Wikipedia  Regarding the section youve added   to the criticism section of Windows Vista  Firstly the criticism section is supposed to be a summary of main article Criticism of Windows Vista any criticsm should be added to that article first and only then summarised for the Windows Vista article  Secondly the paragraph you added did not cite any sources  Adding content without citing a reliable source is not consistent with our policy of verifiability  This is especially true when the added material appears to be contradicted by other articles the sentence XPDM drivers supported Vista Aero in the beta versions of Windows Vista appears to be contradicted by the WDDM article and in any case gives the rather misleading impression that all graphics cards could run Aero in Vista beta which is obviously untrue  I have removed the paragraphs for now please feel free to reinsert it into the Criticism article rather than the main Vista article at first when you have located some verifiable sources to support the text  If you have any questions about this please leave a message on the Windows Vista talk page or if you have any questions for me in particular   For general questions you can type helpme on your user page and someone will show up shortly to answer them Thanks and I hope you enjoy contributing to Wikipedia
