On this page you can download the Windows XP Driver & Application pack, version 2.3 in English.

The driver pack is compatible with all Sony VAIO UX computers.

Installation instructions

- If your computer has no operating system, install a fresh copy of Windows XP first.

- Please confirm you are running XP SP2 or higher ( Service Pack 2 )
- Click on "Start"
- Right click "My Computer"
- Click "Properties"
- You should see "Windows Edition"
- It will list if you are running SP1, SP2 or SP3. If you don't see any mention of a Service Pack, you have the original "RTM" edition of Windows XP and also need to install SP2

- If you are not running SP2 or SP3, please download and install it from Legacy Update's Download Center. Ignore the instructions that it is not meant for updating a single computer.

- Now you can start installing each driver/application. Starting with folder #1 and work your way to the last # -named folder. You can include/exclude any drivers which do not belong to your model. This would include Felica, CXD, WWAN utilities etc.

Once you have finished installing all drivers, and restarted your computer afterwards, everything should work.

Check in "Device Manager" if you see any devices with an exclamation mark. If all drivers installed successfully, there should be none.
