Hello again.

Glad to see you have it sorted and thanks for the update; be sure to disconnect the other HDDs when you get the new SSD and install the new OS.

What prevents you from doing your "casual use' work on 64 bit itself?

Secondly, are you sure the things you plan to use XP for wont run under win7?

Windows 7

I'll be using Win 7 32bit for quite some time because only few of my programs are native x64 applications. Running a 32bit application in a 64bit OS can sometimes lag performance.

XP are needed for my old ISDN terminal and 56K modem for which drivers don't exist (and probably never will) for Win7 32bit. There are also programs and especially some games that can barely run even on XP (eg Nomad Soul) since they were released for older vers of Win. I'm not ready to give up on them so I am still using Win XP when needed.

Have a laptop that had 32bit Vista on it. I bought what I thought was a Windows 8 OS on it but it turned out too be an upgrade disk and we didn't find this out until we kept getting an activation problem. To cut a VERY long story short we have decided to ditch the Windows 8 and go 7. Plus we...
