Windows 10 End of life: what your business needs to do now

`Time is ticking.

On 14th October 2025, Microsoft will officially end support for Windows 10. That means no more security updates, bug fixes or technical help. If your business is still running Windows 10, you’ve now got a ticking time bomb on your hands—one that could leave you exposed to cyberattacks, mounting IT issues, and productivity problems.

At Delta 365, we’re urging all our customers to start preparing now. Here’s what you need to know—and why waiting could cost your business far more than just an upgrade.

What does ‘End of Support’ actually mean?

When Microsoft ends support for Windows 10, every version—Pro, Home, Enterprise, Education, Workstation—will stop receiving:

• Security updates

• Bug fixes

• Technical support

• Performance improvements

That leaves your business exposed. Hackers know when support ends—and they target systems that can’t fight back.

The risks of not upgrading

Yes, your PCs will still switch on. But they’ll quickly become a major liability:

• Cybersecurity risk skyrockets: Devices without updates are wide open to malware, phishing, and ransomware.

• Increased IT overhead: Without automatic patches, your team (or outsourced support) will spend time and money firefighting.

• Compatibility issues: New software and apps won’t support Windows 10, causing crashes or failures.

• Lost productivity: The longer you leave it, the more performance dips and system slowdowns you’ll face.

Features built into Windows 11, such as credential safeguards, malware shields and application protection, have led to a reported 58% drop in security incidents, including a 3.1 times reduction in firmware attacks.That’s not an upgrade, that’s peace of mind.

Windows 11 isn’t just new—it’s smarter

Windows 11 isn’t just about better security. It’s built for modern business:

• 42% faster completion of heavy workloads

• 50% faster workflows

• 80% drop in helpdesk tickets

Multiple studies of Windows 11 Pro on new devices reveal a raft of business benefits, including 42% faster completion of demanding workloads on average, 50% faster workflows on average and 80% reported reduction in helpdesk tickets (source: Microsoft).
