How to switch to 64-bit Vista

Im thinking of switching to 64-bit Vista so i can put 4 GB of RAM in my computer. Is the switch as easy as just putting the 64-bit CD in and reinstalling Vista? Will it replace the old vista files, or will it erase my Hard Drive? Also, will i have to re-install all my programs to support 64-bit? THanks

  1. i believe you have to do a complete reinstall
    I don't think its an upgrade.
    But all the programs you have running now (except old ones w/ a 16 bit installer) should work fine on the x64 Vista
  2. But if its a complete reinstall, then im going to have to end up reinstalling all my programs again right?? And will i lose all of my data on my games that i have to reinstall?
  3. correct
  4. Yes, no upgrade but clean installation (ain't not better a clean installation vs an upgrade? :))

    We will all need eventually to move to the world of x64 one day anyway.
    I believe Vista was supposed to be x64 only initially. The world of drivers was not ready.

    I'm surprised Windows 7 is still available in 32bits?
  5. Technically, Vista 64-bit is a whole different OS.

    So it's as if you are going to switch to Linux. But of course, most windows programs still work.

    will my 2 GB of DDR3 memory not be as good as it is now on 32-bit? Im planning on buying another four GB, but i dont know if x64 requires more RAM to even run smoothly
