When to Replace Business Computers, Servers and Network Equipment

• The operating system no longer receives security updates, or the computer cannot run the current version.
• Employees wait on the computer every day: slow start-up, frozen applications or not enough memory for the tools they use.
• Batteries, keyboards, screens or drives keep failing on the same machine.
• The warranty has ended on a computer that someone cannot work without.
• New business software or security tools do not support it.

• The server operating system or a key application is near or past its end-of-support date.
• Hardware warnings appear for disks, power supplies or memory, or the warranty and parts support have ended.
• Storage is close to full, or backups and restores take longer than the business can accept.
• The workload could move to Microsoft 365 or another cloud service instead of a new server.

• The manufacturer no longer releases firmware or security updates for the device.
• The firewall’s security subscriptions or support have lapsed.
• Internet speeds have increased but the firewall or switches cannot keep up.
• Wi-Fi coverage or capacity no longer fits the office, or older access points cannot use current security settings. See network security services.

Once a manufacturer stops releasing security updates for a device or operating system, new weaknesses are no longer fixed. The equipment may still work, but it becomes easier to attack, and cyber insurance questionnaires often ask whether you run unsupported systems. See our cyber insurance requirements checklist.

Windows 10 is a current example. Microsoft ended support for Windows 10 in October 2025, so computers that cannot run Windows 11 no longer receive regular security updates unless they are enrolled in Microsoft’s paid Extended Security Updates program. Those computers belong at the top of a replacement plan.

• Keep an inventory of every computer, server and network device, with its purchase date, warranty end date and the vendor’s support end date.
• Rank by business impact. A server or firewall the whole company depends on comes before a spare laptop.
• Budget by year so replacements are spread out instead of arriving all at once. See our IT budget planning guide.
• Standardize models where you can, which makes setup, support and spare parts simpler.
• Plan the move for each replacement: data transfer, setup, testing and a time that does not disrupt work.
• Retire old equipment securely by wiping or destroying drives and recording what was disposed of.

A repair makes sense when the equipment is still supported, still under warranty or close to it, and fast enough for the work. Replacement usually makes more sense when the device no longer gets security updates, when the same problem keeps returning or when the repair would cost a large share of a new device.

Count the cost of the time employees lose to a slow or unreliable machine, not only the repair bill.

Our remote monitoring tracks the health of every managed device, and findings such as aging equipment, recurring issues and devices that missed an update feed the technology roadmap and budget reviews in our IT consulting and virtual CIO services.

We plan replacements with you, order and set up new equipment, move data, retire old devices securely and keep the inventory current as part of our managed IT services.
