LiteralKa sends in a poorly sourced Reg story claiming that Microsoft has granted OEMs six more months to sell PCs using Windows Vista with the support to downgrade to Windows XP. OEMs can now offer such arrangements until July 31, 2009 — the previous deadline was January 31, 2009. The article claims as source "a Reg reader" without further details. Neither Microsoft nor any OEM has confirmed the rumor, and only a few scattered bloggers have picked it up.
