Windows 10 on Office PCs: Pay for Extended Updates, Upgrade or Replace?

The accounts PC that runs your payroll software, the reception computer that's been there since 2017, and a row of staff desktops that still boot fine every morning. For many small and mid-sized offices in Kuala Lumpur, these machines are still on Windows 10, and the question on every owner's mind is the same: do we pay to keep them protected, upgrade them, or finally replace them?

Windows 10 reached end of support in October 2025. Since then, office PCs only receive security updates through Microsoft's paid Windows 10 Extended Security Updates (ESU) for businesses, and the price per PC doubles every year. Year 2 of the programme starts on 14 October 2026, which makes this the right time to decide. Unlike the free programme for home users, which now runs to October 2027, office PCs have no free option.

If you're searching Windows 10 ESU for business or Windows 11 upgrade for office PCs KL, this guide compares the three options and how we help offices decide machine by machine. We're KL Computer, with four permanent branches across Kuala Lumpur and 12 years supporting office IT. See our full range of business IT services for what else we cover.

What Windows 10 ESU Costs for Businesses

Microsoft's business ESU programme runs for a maximum of three years, priced per PC, with the cost doubling each year. Prices below are Microsoft's published USD list prices; local resellers quote in RM.

• ✓Joining late costs more. ESU is cumulative, so an office that signs up in Year 2 must also pay for Year 1. For 10 PCs, that's $183 per PC, or $1,830 before your office has upgraded anything.
• ✓Security fixes only. ESU keeps Windows 10 patched, but adds no new features and no general technical support.
• ✓Software support is moving on. Accounting systems, browsers and bank portals gradually drop support for older Windows versions, even on patched PCs.
• ✓A hard stop in 2028. After Year 3, there are no more updates at any price, so ESU only delays the decision.

The Three Options Compared

Most offices don't pick one option for every machine. The right answer usually depends on each PC's age and hardware.

Replacing doesn't always mean buying new. Business-grade refurbished desktops and laptops that already run Windows 11 can be a cost-effective way to replace several older PCs at once.

How to Decide, PC by PC

From the office audits our technicians carry out, these are the questions that settle the decision for each machine.

How We Handle Your Office Migration, Step by Step

Here's how we take an office from a mix of Windows 10 machines to a plan that fits your budget.

• 1.PC Audit. We list every machine, its age, hardware, Windows version and the software it runs.
• 2.Upgrade, Pay or Replace Plan. Each PC gets a clear recommendation with costs, so you can compare ESU against upgrading or replacing before committing.
• 3.Backup First. Important files, email and application data are backed up before any machine is touched.
• 4.Onsite Upgrade or Replacement. We upgrade Windows, fit SSDs or RAM, or set up replacement PCs at your office, scheduled to keep downtime low.
• 5.Test Before We Leave. We check that software, printers, shared drives and email work on every machine before closing the job.
