Hi,
Thank you for writing to Microsoft Community Forums.
Congratulations on your purchase of a New PC.
I understand that you would like to know if you can install the updates from Dell.
A driver is a small but essential piece of software that is written for a specific operating system like Microsoft Windows 10. The operating system uses the driver to communicate with a hardware device such as a printer, video card, sound card, network adapters, etc. Microsoft Windows operating systems includes drivers for most devices, however, device-specific drivers may need to be downloaded and installed from the manufacturer's website. Without drivers, the devices that you connect to your PC would not work properly. Dell develops drivers so that the operating system on your Dell PC can work with your Dell devices and applications. This ensures that your device optimized and up-to-date.
Dell releases updated drivers frequently to ensure that your PC the latest security patches, fixes, and functionality available. When you update your drivers, you are taking a preventative measure to protect your PC and make sure your hardware and devices work properly.
For more information about driver updates from Dell, you may refer Drivers and Downloads FAQs.
