Still Running Windows 10? Here's What CPA Firms Need to Know Before It’s Too Late

Let’s not sugarcoat it: Windows 10 is retiring.

As of October 14, 2025, Microsoft will stop supporting Windows 10. That means:

  • No more security patches
  • No more bug fixes
  • No more support from Microsoft

For accounting firms in Greater Boston and the South Shore, this isn’t just an IT upgrade — it’s a compliance, security, and productivity moment of truth.

“We’ll Deal With It Later” Is a Costly Game

We know — replacing computers isn’t topping your wishlist. You’ve got taxes to file, audits to prep, and clients to keep happy.

But putting off the switch can cost you far more than new hardware. Let’s break it down.

  1. You Lose Your Cybersecurity Safety Net

Unsupported systems are sitting ducks.

Once Microsoft stops patching vulnerabilities, cybercriminals will start circling. If you're handling sensitive client data (and you are), this is non-negotiable.

One breach could mean:

  • A ransomware lockdown
  • Client trust loss
  • Compliance fines

Outdated systems are the #1 soft target for cyberattacks.

  1. Compatibility Issues Will Sneak Up on You

Think your tax software or QuickBooks will keep running smoothly on Windows 10? Think again.

Most major business apps are already phasing out support. And it’s not just software — your printer drivers, encrypted email tools, even your remote access security might break without warning.

Picture this: Your best client’s file won’t open during a Zoom meeting. Worth it?

  1. Productivity Drags = Profit Drags

Old systems crash more. They lag. They irritate your staff. And they waste time — the most valuable thing during tax season.

If each employee loses 15 minutes a day? That’s hours of billable time gone every week.

  1. Emergency Upgrades = Emergency Prices

Wait too long, and you’ll find yourself in “panic mode”:

  • Rush orders on hardware
  • Overtime IT labor
  • Downtime during client deadlines

Planning ahead = predictable costs. Waiting until October = chaos.

  1. Compliance Red Flags Are Looming

If your firm handles any regulated data — think WISP, GLBA, or IRS Pub. 4557 — unsupported systems can mean:

  • Audit failures
  • Insurance claim denials
  • Potential fines or lawsuits

That’s not a risk any licensed firm should take.
