    I recently upgraded my computer (specs below) :

    Tech Support Guy System Info Utility version
    OS Version: Microsoft Windows 7 Home Premium , 32 bit
    Processor: AMD Phenom(tm) II X6 1075T Processor, x64 Family 16 Model 10 Stepping 0
    Processor Count: 6
    RAM: 3199 Mb
    Graphics Card: ATI Radeon HD 5700 Series, 1024 Mb
    Hard Drives: C: Total - 953766 MB, Free - 584389 MB;
    Motherboard: MSI, 870U-G55 (MS-7599), 5.0, To be filled by O.E.M.
    Antivirus: AVG Anti-Virus Free Edition 2011, Updated and Enabled

    This has now put me in a position where i can upgrade to windows7 64bit! JOY!!

    After updating my system i realised i must reinstall windows7 (32bit) back onto my computer thus creating a separate folder marked "windows.old" where all my files where now kept...

    My question is that if i were to upgrade to 64bit (possibly using windows anytime upgrade service?) would i have to go through the process of reinstalling all my programs again?

    N.B. The reason im doing this is because i have been informed that i will be able to use more of my 8GB RAM since you can see above it is only registering at appropriately 3GB.

    Thanks in advance!

    From: Upgrading to Windows 7: frequently asked questions

    Will I lose files, programs, or settings when I install Windows 7?

    An upgrade installation of Windows 7 will keep your files, programs, and settings in place. A custom (clean) installation doesn't preserve your files, programs, or settings. If you plan to do a custom installation of Windows 7, be sure to back up your files and other information first. You'll also need to manually reinstall your programs. For more information, see "Installing and reinstalling Windows 7"

    I'm pretty sure that any time you go from 32-bit to 64-bit, whether the same version of Windows 7 or not, you have to do a custom (clean, fresh) install. I don't have time to search right now to confirm.

    Yes, to install 64 bit OS on a 32 bit OS must be done with a CLEAN install, a upgrade will NOT work.
    So back up ALL data, find all of your program installs including CD's and downloaded programs.

    Then you can do a clean install and start over installing your programs and data.

    Also you will need to get 64 bit drivers for your printers, scanners and other devices that require them.
