I am awaiting delivery of the items in the link below for my first self build. I have researched as much of the why's and wherefore's as possible and now that the parts are in transit I spent a few hours today making some back ups of my files etc to transfer over to the new PC. I will be going from a 7yr old Win XP Home 32 bit system to Windows 7 64 bit system. I downloded new versions of Comodo CIS, Panda Cloud Antivirus, Superantispyware and SpywareBlaster and realised that there were 32 & 64 bit versions. As I had intended to install the 64 bit system I started to think about any incompatibilities I might encounter as I will probably attempt to download and install the same programs I have at present with the Win XP 32 bit system checking of course to see if they are at all compatible. I did a search on Google and read some articles in regard to 32 & 64 bit technology but found that it was either vague or went over my head. Can anybody point me in the right direction or explain in simple terms the pros and cons of this , eg will 32 bit programs like Revo Uninstaller work on a 64 bit system like the one in the link below. I just noticed that some of the parts are now saying out of stock but this was added after I bought mine. Thanks in advance.

Its hit and miss whether a 32 bit program will run on a 64 bit OS-more hit then miss these days, they do a good job of backwards compatibility so chances are they will run, but if one has a 64 bit OS then it is always the best idea to get 64 bit software for it, especially when it comes to anti virus programs and firewalls, and other security related software-these are the most likely not to work, and if they do will likely not provide as adequate protection.

In the years since I have run 64bit OSs, I have had 2 programs that gave me problems. None of the major programs cause problems. It is usually the smaller niche products that are either discontinued or not updated by their publisher.

No real reason to use a 32bit OS now.

I've been running a 64-bit operating system since Vista first launched. All of my games and productivity applications work fine. 32-bit applications run within WoW64 far better in Vista and 7 than they did in XP 64-bit, which is good for compatibility reasons. Deep level applications, such as security programs and antivirus/malware programs, are very specific as to which they will work with. If you're a standard home user or even a small business user, there is no reason to go for 32-bit especially if you use 4GB or more of RAM. Windows 7 does have some 64-bit specific security features, which is yet another reason to use it. If you have 64-bit specific programs, they will always run better in 64-bit as they can access different CPU instruction sets and use more memory than a 32-bit application running in WoW64 emulation. Nevertheless, many gamers use 64-bit since very few 32-bit games take a significant performance hit when running in 64-bit Windows. When I first installed Vista 64-bit, I did have a few issues, but updates corrected those. Now, if I have a problem, it is because of the OS version, Windows 7, rather than the bit version it is running.

Thanks a lot for the replies, 64 bit it is then.
