Need Video card driver info?
 

If it works then don't fix it. You can check which version you are using and dump the others but the diskspace saved is probably not worth the effort.

All you have to do is update when a new graphics driver becomes available. I wouldn't necessarily stay with a really old driver even though it is working. Many times new graphics drivers allow a card to process faster or have features not available previously. I stay away from the beta's though. If the new driver does not work you can always go back to the previous version until a newer version is available. I keep a copy of the old version in my download folder just in case the new one does not work well.
