Windows 11 Hardware
& Upgrade Guide for
Small Businesses
For small businesses preparing to leave Windows 10, this guide covers Windows 11 hardware requirements and a rollout strategy for a smooth upgrade.
Support for Windows 10 ended on October 14, 2025
Microsoft no longer provides security updates, patches, or support—and businesses that don’t upgrade will face serious cybersecurity and compliance risks.
​
This free checklist from TEC Services will walk you through exactly what you need to check before upgrading, so your organization is ready to transition safely and efficiently.
Hardware Requirements (Per Microsoft)
Use this list to determine if your machines are eligible for the Windows 11 upgrade:
-
64-bit processor, 1 GHz or faster with 2 or more cores
-
4 GB RAM minimum
-
64 GB storage minimum
-
UEFI firmware with Secure Boot
-
TPM version 2.0
-
DirectX 12-compatible graphics / WDDM 2.0 driver
-
High-definition display (720p) with 9”+ screen
-
Internet connection and Microsoft account required for setup
Pre-Upgrade Planning Guide
Before you click “Install,” follow this checklist:
-
Complete a full hardware inventory
-
Check application compatibility with vendors
-
Ensure 20–30 GB of free storage per device
-
Back up your data (and test the backups)
-
Review ISO file size (6.3 GB) if downloading manually
-
Identify devices that may need replacement instead of upgrade
Deployment & Rollback Considerations
-
Schedule upgrades during off-hours to reduce downtime
-
Pilot upgrade on 1–2 devices before full rollout
-
Document license keys, critical workflows, and network settings
-
Prepare rollback tools in case of compatibility failure
Why This Matters
An unsupported OS means:
-
No more security patches
-
Increased risk of ransomware and data breaches
-
Software vendors may stop supporting your tools
-
Regulatory compliance (HIPAA, PCI, etc.) may be compromised
FAQs
What if a device fails the CPU or TPM 2.0 check?
For older hardware, replacement is often more cost-effective than forcing an unsupported path. We’ll help you weigh ESU (short-term) vs. replacement.
How long does a typical rollout take?
Pilots can be done in days. Full deployments usually take 2–4 weeks depending on app testing and device count.
Can you work after hours?
Yes—most SMBs schedule wave cutovers during evenings or weekends to reduce disruption.
Will my antivirus and VPN still work?
Most modern EDR/AV and VPN clients are Windows 11 compatible, but versions matter. The checklist includes vendor-check steps.
Do you support mixed environments (Windows 10 + 11)?
Yes. We’ll set patch rings and policies that account for both during transition.
What about legacy printers and niche peripherals?
We’ll test drivers during the pilot and document any workarounds or replacement options.
