Using an prebuilt computers (no matter it’s a desktop or laptop), have a disadvantage : It’s very difficult and dangerous if you install the other OS, not the included one. It’s still possible if the manufacturer provide drivers that works for specific OS. For example, my Sony VAIO VGN-CR23G shipped with an ORIGINAL Microsoft Windows Vista operating system. In Sony Asia Pacific website, they provide drivers for Windows XP users, for everyone who install a Windows XP in that VAIO. So, installing Microsoft Windows XP in my VAIO is possible, and not dangerous. But, how about the new Microsoft Windows 7 ? I’ve try it!

Sony hasn’t provide us with Windows 7 drivers. But, I’ve successfully upgraded a Sony VAIO VGN-CR23G without any problems.

Here’s what I do :

  1. It’s recommended to reinstall the Windows Vista first.
    1. Open the VAIO Recovery Center
    2. Click “Restore C: Drive”
      1. !!!ATTENTION!!! Your C: drive will be formatted (all files in it will be deleted), make backup first!
    3. Follow the instruction
  2. It will take 1-3 hours
  3. Now, install the Windows Vista Service Pack 1
  4. Uninstall Norton 2007
  5. Uninstall Microsoft SQL Server 2005
  6. Insert your Windows 7 disc (I have the Release Candidate one (build 7100))
  7. Click “Install Now” & follow the instructions
    1. Do not get latest updates
    2. Select “Upgrade” instead of “Custom (Advanced)”
  8. It will take 2-4 hours
  9. Now, everything will be fine except audio and Bluetooth
  10. For Audio driver :
    1. Open High Definition Audio Codecs (Software)
    2. Check “I accept to the above”
    3. Click Next
    4. Beside Vista, Windows7 Driver (32/64 bits) Driver only (Executable file), click one of the first 3 “GO”s
    5. Download
    6. Install
    7. Restart your VAIO
    8. Run the installer again
  11. For Bluetooth driver :
    1. Download the Vista Bluetooth driver
    2. After the download complete, locate the setup file with Windows Explorer
    3. Right click on the installer (default name : Bluetooth.exe)
    4. Click “Properties”
    5. Click “Compatibility” tab
    6. Click “Change Settings for All Users”
    7. Check “Run this program in compatibility mode for :”
    8. Select “Windows Vista” from the drop-down menu
    9. Click OK two times to OK both windows
    10. Open the Wireless Utility
    11. Check all 3 options (2.4 GHz & 5 GHz WLAN and Bluetooth)
    12. OK
    13. Make sure the “WIRELESS” switch is on (on the left side of the VAIO)
    14. Run the installer
  12. Done, you have the Windows 7 on your VAIO.
