Hi guys I agree absolutely that in general a Clean install is usually a better approach however in the case of a Beta that might not always be a good idea. In the case of Windows XP ===> W7 X-32 there are some drivers that Vista hasn't got yet - even though though in some cases the XP version will work. With a Clean install -- these programs for me would not work. NO LAN connection even though my Via velocity family gigabit ethernet card was reported as working correctly and using the latest driver. Hauppage Win TV tuner wouldn't work for Digital channels (was OK on analog). Epson 1290 Photo Printer stubbornly refused to do anything (again Windows reported driver as working 100%.. Winamp failed to show any options for CD ripping -- I rip to FLAC a lot so this is a MUST program. Windvd did work but was a bit of a pain to get it to go --needed a few installs. Some Stock exchange "Charting Software" would only give me blank screens. (Applications actually written for XP). So I did XP==>Vista Ultimate X-32==> W7 X32. Guess what --the WHOLE Kybosh worked first time. I did all the VISTA updates before going from Vista Ultimate to W7. My Vista Ultimate was "Borrowed" from another computer so I didn't activate it. You can still get 30 days so no prob there and the Windows 7 activation doesn't check whether the previous version of Windows you upgraded from was activated or not. You can't do this trick to upgrade XP PRO via Windows Vista Home premium -- only works with VISTA Ultimate. I tghink the upgrade process seems to think if the XP working driver is OK then don't bother doing anything -- or perhaps it automatically sets the "Program Compatability" levels in ways I don't know about. The inner workings of Windows in any case are beyond the understanding of "lesser mortals" like me. Anyway you've got one Very Happy Camper now even if it a bit of a long winded way to get to W7 ftom XP. The only program I had to uninstall was NERO -- worked again on re-install. Alcohol 52 doesn't work but I knew that anyway and I have some really old legacy hardware which I also knew about -- Windows XP Virtual machine handles these. So whilst in general if you've got Networking or some other intractable problems on a clean install it might be worth your while also doing waht I did --just takes a bit of extra time and you need to find a Vista Ultimate X-32 image somewhere - just borrow one from a colleague / work - you aren't actually going to activate it but just use it as a One Time Migration tool. Cheers after a long night, now a nice glass of Scotch (or two) and I can go to bed happy. Jimbo.
