Choosing a business PC: specifications that match the job

Reviewed and updated on 20 October 2026.

A business computer needs to run the applications your staff use comfortably, connect to their equipment and remain supportable throughout its working life. The cheapest purchase price tells you little about the cost of slow performance or a failed device.

Windows 11 minimums and a practical buying specification

Microsoft lists 4 GB RAM and 64 GB storage among the minimum requirements for Windows 11. Devices must also meet its processor, firmware, graphics and TPM requirements. These are installation requirements, not a recommendation for a busy working day. Check Microsoft’s current specifications before buying or upgrading.

For general office work, 16 GB RAM and a 512 GB SSD are useful starting points to discuss. They are not universal minimums. Large spreadsheets, design software, development tools and local virtual machines may need more memory, storage or dedicated graphics. Check the application supplier’s requirements and test a representative workload.

Choose around the person using it

  • Office staff: check performance with email, browser tabs, video calls and business applications open together.
  • Mobile staff: consider weight, battery life, screen visibility, connectivity and charging arrangements.
  • Design and engineering teams: check graphics certification, memory and storage against the software and project files in use.
  • Shared desks: test the docking station, displays, headset and other peripherals.

Look beyond processor and memory

Check build quality, ventilation, keyboard comfort and the availability of repairs. Keep vents clear and follow the manufacturer’s guidance on positioning and charging. A laptop stand can improve desk ergonomics, but it does not guarantee a particular performance or battery-life gain.

Compare warranty and replacement arrangements

Read the warranty terms: what is covered, where repairs take place and how quickly the supplier aims to respond. Compare an extended warranty with the cost of a spare device and the disruption a repair could cause.
