Hi Linda,

If you are asking about the Windows Drivers, then it is free to update them.

Windows Update checks for updated drivers and software for your devices and install them automatically.
Keeping Windows Update on a good way to make sure your devices continues to work properly and you get the best experience with them.

Just follow the below steps:

1. Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
   (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)
2. Tap or click Update and recovery, and then tap or click Windows Update.
3. Tap or click Choose how updates get installed.
4. Under Important updates, choose Install updates automatically (recommended).

If you are asking to update from Driver Reviver, you can follow the below steps:

1. Launch Driver Reviver and click the Start Scan Now button to start scanning your PC.
2. Wait for the scanning process to complete.
3. Review the scan results and click the Update All button to update all outdated drivers on your computer.
4. Driver Reviver will now download the updates for your drivers, backup your original drivers and then install the latest updates for your computer drivers. This may take a while depending how many drivers you are updating on your computer and the size of the downloads.
5. Once the updates are installed, you will see a quick summary of your drivers and your PC’s status changes to Excellent.

I hope this helps.

Thanks,
Lokesh
