After reading all the comments, I read your's. It was the most thought provoking, and decisive that I have seen (to date).
My situation and problem with Vista has been discussed in Photo and Video forums. Your earthy comments about 32 bit vs 64 bit were most appreciated. None of that techno answers and passoff links! Now, for my problem, and maybe your advise, and others to comment.
My present system:
HP8100CTO 5600+ 2.80Ghz Media Center
AMD Athlon 64 X2 Dual Core Vista 32-bit OS
4 GB PC-6400 (800 MHz) DIMMs
One Terrabyte ST310000528AS drive, DVD burner, HD DVD player
PCI-E Nvidia GeForce 8500GT 512MB graphic card
Asus M2N68-LA motherboard with WinTV-HVR-1800 dual tuner
ESata Dock to support swapping out OS with five other Terrabyte drives. Using Seagate Disk Wizard to clone OS and all partitions.
Special note: HP6122 printer with duplexer. HP992c Vista driver.
Solutions I am trying for Photo problem, per linked discussions:
(1) removed USB IR remote control sensor
(2) Installed manufacturer's newest Nvidia GT8500GT drivers.
(3) Removed all corrupted jpegs. Un-installed Picasa3, and re-installed it to erase all thumbnail data.
(4) Bought replacement video card, ATI 5670 1 GB Ram. Have not committed this card, as yet. Will do so before Windows 7.
With all the drives, I can protect Vista 32 bit, and opt for several variations to the Windows 7 upgrade.
Now that I clone my system, and will not suffer a loss, my question!
I bought Windows 7 upgrade. My options are as follows:
(1) Make the upgrade into 32 bit Windows 7.
(2) Use option to install Windows 7 with 64 bit.
(3) Download Windows Live module for Media Center support. Hopefully these all work in 64 bit also?
Hopefully someone has made the leap, and downloaded all modules to make the transistion work? Need to know what to expect!
