There are times when you install an ungrade to a device driver but instead of getting an upgrade you get downgraded in the sense that either you loose on performance or its stoping functioning at all. In situation like this where you are still able to logon with System priviledges, you can roll back the driver. Even though this can not be considered as a tweak, but it could save you a good deal of time and disappointment. Here are the steps: Step:1 Log in with an administrator account Step:2 Right click on My Computer Step:3 Select Properties Step:4 Click on the Hardware tab Step:5 Click on the Device Manager button Step:6 Select the device you want to rollback or reconfigure Step:7 Click on the Driver tab and then click on the Roll Back Drive button
