🚨 Critical Security Alert 🚨

Windows 10 Support Has Ended.
Is Your Business Protected?

As of October 14, 2025, Microsoft permanently stopped all security updates, patches, and technical support for Windows 10. Every device still running it is an open door to ransomware, compliance violations, and costly downtime.

This is not a future risk — it is happening right now.

⏱️ End of Life: October 14, 2025 — Support Permanently Ended

The Real Cost of Staying on Windows 10

Every day your business runs on Windows 10, your attack surface grows. Here's what's at stake without security updates.

🛑

Zero Security Patches

Every new vulnerability discovered from now on will remain permanently unpatched. Attackers actively target end-of-life systems because they know the holes will never be fixed.

⚠️

Compliance Violations

Running unsupported software violates HIPAA, PCI-DSS, SOC 2, CMMC, and NIST requirements. Auditors and regulators are already flagging Windows 10 systems as non-compliant. Learn how our cybersecurity solutions keep you audit-ready.

💰

Ransomware Exposure

Unpatched operating systems are the number one entry point for ransomware. Small and mid-size businesses are the most frequent targets, with average recovery costs exceeding $200,000. Our managed services provide 24/7 threat monitoring to prevent attacks before they start.

💻

Software Incompatibility

Microsoft 365, Teams, Edge, and major business applications are dropping Windows 10 support. Critical tools your team depends on will stop receiving updates and eventually stop working.

📉

Cyber Insurance Risk

Insurers are tightening requirements around supported operating systems. Running Windows 10 could void your cyber insurance policy or significantly increase premiums at renewal. Explore our cloud services to modernize your infrastructure alongside your OS upgrade.

⏱️

Increasing Downtime

Without support, driver conflicts, hardware issues, and software crashes become harder and more expensive to resolve. Your team loses productive hours every week to preventable IT problems.

From Windows 10 to Windows 11 in 5 Steps

A structured, low-risk approach that keeps your business running while we handle the technical heavy lifting.

1

Discovery & Assessment

We inventory every device, check Windows 11 hardware requirements (TPM 2.0, Secure Boot, CPU compatibility), audit installed software, and identify any blockers before creating your migration roadmap.

2

Planning & Scheduling

We design a rollout schedule around your business operations — department by department, site by site — so no team loses productivity. Devices that need replacement are sourced and pre-configured.

3

Pilot Deployment

A small group migrates first. We verify application compatibility, test user workflows, and resolve any issues before the full rollout begins. This catches problems early and eliminates surprises.

4

Full Migration Rollout

Devices are upgraded in planned waves. User data, profiles, printers, and settings transfer automatically. Security policies, encryption, and monitoring tools are applied to every machine.

5

Validation & Ongoing Support

Post-migration, we verify every device, confirm compliance posture, and provide dedicated helpdesk support. Your team gets direct access to our engineers for any questions or adjustments.

Stay Compliant After Migration

Running supported operating systems isn't optional for regulated industries. We ensure your migration meets every framework requirement.

🏥

HIPAA

Healthcare organizations must run supported systems to protect patient data. We configure encryption, access controls, and audit logging.

💳

PCI-DSS

Payment processing requires patched, supported operating systems. We ensure your environment meets PCI requirements end-to-end.

🛡️

SOC 2

Trust service criteria demand supported software. We document your migration and configure controls that satisfy SOC 2 auditors.

🏛️

CMMC / NIST

Government contractors must meet strict cybersecurity maturity requirements. Unsupported OS is an automatic finding — we eliminate it.
