Is the HP 21.45-inch all-in-one good for schoolwork?

Yes for essays, browsing, video classes and Office-style apps. It is not suited to engineering software, gaming or heavy video editing.

Can I upgrade the RAM or storage?

HP all-in-ones in this class usually have limited upgrade options, and the listing gives no upgrade details. Plan on using cloud or external USB storage for the 128GB drive.

What does Windows 11 Home in S Mode mean?

S Mode only runs apps from the Microsoft Store and locks the default browser to Edge. You can switch it off once for free in Settings, after which regular Windows apps install.

Does it come with a keyboard and mouse?

A wireless keyboard is included. The listing does not mention a mouse, so check before buying or plan to add one.

Is the screen touch-enabled?

No. The 21.45-inch FHD display is a standard non-touch panel.

Is $199 a good price?

It is low for a complete all-in-one with a keyboard, but only one store lists it new at $199 as of November 5, 2026, so there is no recent range to compare it with.

Our take on the HP 21.45" All-in-One Desktop, Intel Pentium, 8GB RAM, 128GB SSD

This is HP's entry-level all-in-one: a 21.45-inch FHD screen with a four-core Intel Pentium, 8GB of DDR5 RAM and a 128GB SSD, sold with a wireless keyboard. It runs Windows 11 Home in S Mode, so apps come from the Microsoft Store until you switch S Mode off. The 128GB drive is small for a family machine, and the display is not touch. At $199 at ndomzy.com as of November 5, 2026, it is a low price for a complete all-in-one, but only one store lists it new, so there is no price history to compare against.
