Is there any chance of getting all of the Windows Server 2003 x64 updates onto XP x64? Someone just suggested I ask my question in this thread, and TIA for any help. Earlier today, I attempted to download the three available updates for Server '03 and install them manually onto my XP x64 laptop. I had no trouble with MS14-026 (using the .NET 2.0 version; I don't have 4.0 installed so I didn't try that one) or 029. However, MS14-027 failed. A check of the .inf files inside the update revealed that Microsoft put in a block in "update_SP2QFE.inf" that prevents it from installing on XP x64: [Prereq.XPAMDInstallBlock.Section] PresentOp=CheckReg,HKLM,"SYSTEM\CurrentControlSet\Control\ProductOptions",ProductType,0x00000000 NotEqualOp=CheckReg,HKLM,"SYSTEM\CurrentControlSet\Control\ProductOptions",ProductType,0x00000000,!=,"WinNT" Display_String="%WrongProductMessage%" Is this update legitimately not suitable for XP x64 for some reason, or is Microsoft just being a PITA about it? And if it's the latter, how hard would it be to hack it to run? Would like to keep this machine on XP x64 as long as I can. It's a Dell Inspiron 1545 with a T9800, and it can run 7, but feels like it's running in mud compared to XP x64.
