Hi, I'm trying to get a Windows version onto my Mac. Right now, I have the full version of Windows XP Professional SP 1a. (Dont say anything about Vista; I already have this and I'm not intending to buy Vista soon.) I'm trying to slipstream a later service pack. As I understand (or looked around), XP 32-bit is better than XP 64-bit (correct me if I am wrong). So is there a 32-bit version of SP3? I dont think there is one. In my search on the Microsoft Download Center, I could not find one. If there isnt SP3 32-Bit, I will need SP2. I have found a few download links to SP2, but I don't know which would suit me better in my situation. Link 1: http://www.microsoft.com/downloads/...be-3b8e-4f30-8245-9e368d3cdb5a&DisplayLang=en In this link, I do not know if this is a 32-bit or 64-bit version. Link 2: http://www.microsoft.com/downloads/...c0-6283-44c3-bb84-b2f0315b2ae6&DisplayLang=en In this link, it is a 64-bit version, but its specified for XP Pro. Link 3: http://www.microsoft.com/downloads/...10-C232-4644-B828-C55EEC605D55&displaylang=en This one confused me because it said "32-bit x86." I thought that x##=##-bit? So things I need to know: 1. Is there a 32-bit version of SP3? 2. Is is possible to install a 64-bit or 86-bit version of Windows in the first place? (I'm thinking no) 3. If both of the above are "no," then which link would i supposedly use to slipstream my current SP1 CD? I am not very knowledgeable in computers, and my information was concluded from looking around the internet. Correct me if I am wrong anywhere. If there is a link referring to an answer to a question or any additional information needed, please provide it or say so. Thanks in advance.
