When a computer starts feeling slow, the instinct is to replace it. Sometimes that’s the right call, but often a targeted upgrade costing far less than a new PC gives it several more productive years. Since standard Windows 10 support ended on October 14, 2025, many small businesses are deciding now whether to upgrade or replace. Here’s a practical way to decide, machine by machine.

Eligible Windows 10 devices enrolled in Microsoft’s Extended Security Updates program may receive limited security updates temporarily. Check the current Microsoft ESU requirements while planning your migration.

Step 1: Check Windows 11 compatibility first

This is the deciding factor for most machines. Windows 11 requires TPM 2.0, Secure Boot, and a supported processor (check the exact model against Microsoft’s supported processor list). Run Microsoft’s free PC Health Check app on each computer.

  • Passes: the machine is a good upgrade candidate. Keep reading.
  • Fails on CPU: plan to replace it. Running an unsupported operating system on a business PC that handles client data is a security risk that isn’t worth taking.
  • Fails on TPM or Secure Boot only: these are often just disabled in the BIOS/UEFI settings. Check before writing the machine off.

Step 2: Replace the hard drive with an SSD

If a compatible PC still has a spinning hard drive, an SSD is by far the most effective upgrade. Boot times drop from minutes to seconds, and apps open almost instantly.

  • Older laptops and desktops with a 2.5″ bay: a SATA SSD such as the Kingston KC600 512GB. It also supports hardware encryption, which is useful for laptops that leave the office.
  • Newer machines with an M.2 slot: an NVMe SSD such as the Samsung 990 1TB is several times faster than SATA.

Back up first. You can clone the old drive with the SSD maker’s migration tool or do a clean Windows install. A clean install is often the better choice for a slow, years-old system.

Step 3: Check the memory

For everyday office work with a web browser, Microsoft 365 and Teams, 8GB of RAM is the practical minimum today, and 16GB is comfortable. If Task Manager regularly shows memory usage above 80%, adding RAM is an inexpensive fix. Check whether the memory is upgradeable first, because many thin laptops have it soldered to the board.

Step 4: Make sure you’re on the right Windows edition

Many small businesses run Windows Home without realizing what’s missing. Windows 11 Pro adds BitLocker drive encryption, Remote Desktop hosting, Group Policy, and the ability to join Microsoft Entra ID or a domain for central management. For a rebuilt or self-built machine, a Windows 11 Pro OEM license is the cost-effective route. Keep in mind that OEM licenses stay with the PC they’re first activated on.

Step 5: Upgrade the workspace, not just the PC

Productivity often depends more on the desk than on the computer:

  • A second monitor is one of the cheapest productivity gains available. A 21.5″ business display such as the HP E22 G5 fits small desks and has an adjustable stand.
  • A docking station lets laptop users connect monitors, a wired network and peripherals with one cable. Compatible laptops can use the Lenovo ThinkPad USB4 Dock.

When replacing makes more sense

  • The CPU isn’t supported by Windows 11.
  • The machine is more than 6–7 years old and needs both an SSD and more RAM.
  • The battery, hinges or keyboard on a laptop are failing.
  • Upgrades would cost more than about half the price of a comparable new machine.

Don’t forget data security when you retire a PC

Old drives contain client data, saved passwords and email. Before recycling or donating a PC, securely wipe the drive or remove and destroy it. For data that has to travel, an encrypted drive such as the IronKey Basic H350 keeps it protected even if the drive is lost.

A simple plan for your office

  1. Run PC Health Check on every machine and list the results.
  2. Upgrade compatible machines: SSD first, then RAM if needed.
  3. Choose Windows 11 Home or Pro according to your business’s management and security requirements.
  4. Budget replacements for incompatible machines, oldest first.
  5. Wipe or destroy the drives of retired machines.
