Microsoft has long followed a phased approach to supporting its operating systems, gradually retiring older versions as new ones take the spotlight. While it’s not unusual for support to wind down, we’re now entering a critical phase. Windows 7 and 8.1 have already reached the end of their extended support, and now Windows 10 is approaching the same fate—with October 14, 2025, marked as its final curtain call.
But what does "end of support" actually mean? It’s more than just missing out on a few updates. Once support ends, Microsoft stops releasing essential security patches, performance fixes, and technical help. That leaves your systems wide open to vulnerabilities, and your business exposed to serious risks.
This isn’t just a tech issue. A business continuity concern can affect everything from operations to compliance. If you haven’t already started planning, now’s the time to take action.
Timeline Breakdown: When Does Support End?
Understanding Microsoft’s support phases helps clear up a lot of confusion. Each version of Windows follows a lifecycle made up of mainstream support and extended support, and we’re nearing the final chapter for Windows 10.
Windows 7
- Mainstream support ended on January 13, 2015, cutting off general updates, feature improvements, and free technical assistance.
- Extended support wrapped up on January 14, 2020, offering only critical security patches.
- Microsoft extended a paid Extended Security Updates (ESU) program for businesses, which provided limited cover until January 10, 2023. That’s now over.
Windows 8.1
- Mainstream support concluded in January 2018, five years after its release.
- Extended support ended on January 10, 2023, just like the final ESU for Windows 7.
- Unlike its predecessor, Windows 8.1 users were not offered an ESU option, making the cut-off absolute.
Windows 10
- Mainstream support ceased on October 13, 2020, which means no more new features or non-security fixes.
- Extended support remains in place until October 14, 2025, offering security updates but no bells and whistles.
- After that, Microsoft will pull the plug entirely—no updates, patches, or support.
Still Functional But No Longer Safe
It’s a common misconception that Windows will stop working after support ends. In reality, your device will still run, but without updates, it’s a sitting duck for cyber threats, compatibility issues, and compliance headaches. The time to act is now before those risks become real problems.
What Happens After Support Ends?
Once Microsoft ends support, the effects are immediate and often underestimated. Here’s what users and businesses can expect.
No More Security Fixes
Microsoft will stop releasing updates that protect against new viruses and system flaws. Older systems become easy targets for attackers looking to exploit known weaknesses without these fixes.
Increased Risk of Cyber Attacks
Outdated systems are far more exposed to threats like ransomware and data breaches. Without updates, each day you continue using unsupported software adds to the danger.
Compliance Issues
Many industries have strict rules around data protection and system security. Running unsupported software may breach these standards, leading to potential legal and financial trouble.
Software Compatibility Problems
As time goes on, popular apps and services will stop supporting older versions of Windows. New tools may not install, and existing programs could lose essential functions or fail to run properly. Antivirus and productivity tools phasing out support for legacy Windows is already becoming common.
Who Is Still Using These Systems?
Despite the risks, a surprising number of people are still using outdated versions of Windows. Recent figures show that Windows 10 remains in use on over 65 per cent of desktops globally, while Windows 7 still lingers on around 3 per cent, with Australia following similar patterns.
Older systems are especially common in manufacturing, healthcare, logistics, and education industries, where critical software or hardware may not be compatible with newer versions. Government departments and regional offices also tend to lag due to stricter budgets or legacy infrastructure.
So why the delay? For many businesses, the thought of upgrading feels overwhelming. Costs, staff training, potential downtime, and general complexity can all lead to hesitation. Sometimes, it’s simply a case of "it still works, so why change it?"
You’re not alone if you’re still using an older system, but staying there isn’t a long-term option.
Thinking About Upgrading? Check If Your PC’s Up for It
Before moving to Windows 11, knowing if your current setup can handle it is important. Not every machine running Windows 10 is ready for the upgrade. Here’s what your PC needs to qualify:
- Operating System: Must be running Windows 10, version 2004 or later. Free updates are available through Settings under Update and Security.
- Processor: A 1 gigahertz (GHz) or faster processor with at least two cores on a compatible 64-bit processor or System on a Chip (SoC).
- RAM: A minimum of 4 gigabytes (GB).
- Storage: At least 64 GB of available storage. Keep in mind that additional space will be needed for future updates.
- System Firmware: UEFI with Secure Boot capability.
- TPM: Trusted Platform Module (TPM) version 2.0 must be enabled.
- Graphics Card: Must support DirectX 12 or later with a WDDM 2.0 driver.
- Display: A high-definition (720p) display is greater than 9 inches diagonally, with 8 bits per colour channel.
For Copilot PCs—a new range of AI-powered devices—your hardware must also include:
- Processor: A CPU with a neural processing unit (NPU) capable of 40 TOPS, such as AMD Ryzen AI 300, Intel Core Ultra 200V, or Snapdragon X series.
- RAM: At least 16 GB of DDR5 or LPDDR5.
- Storage: 256 GB SSD or UFS.
You’ll also need internet access and a Microsoft account for setup and updates, especially if switching from Windows 11 Home to S mode.
What Should You Do Next? A Step-by-Step Plan
Here’s a simple, structured approach to help you move forward with confidence.
a. Audit Your Systems
Start with a complete overview of your current setup.
List every device running an outdated version of Windows, including desktops, laptops, and any hidden terminals or kiosks.
Take note of all the software installed—especially tools critical to your daily operations. This will help you understand any compatibility issues you might face during the transition.
b. Assess Business Needs
Not all devices need the same attention.
Identify which machines are still essential and worth upgrading and which can be retired.
Review how each system is used, which teams rely on them, and if any outdated programs are tied to older Windows versions.
Understanding this will help decide which devices need a fresh start and which can be phased out.
c. Choose a Path Forward
Once you know what you’re working with, explore your upgrade options.
Some systems may be compatible with Windows 11—a direct upgrade can be a simple fix.
Others may be too old to run newer software, so replacing them with modern machines might be the better choice.
Now is also a great time to consider moving part of your operations to the cloud, using solutions like Windows 365 or virtual desktop setups. These can offer more flexibility and reduce hardware dependency.
d. Plan the Rollout
A successful transition comes down to good planning.
Decide if you’ll do a phased rollout—updating small teams at a time—or switch everything over at once.
Make sure your team knows what’s happening and when so they’re not caught off guard.
Don’t forget to schedule backups and planned downtime to prevent data loss and disruptions during the switch.
Windows 11 and the Alternatives: What Are Your Options?
Upgrading your system doesn’t always mean sticking with the same setup. For many businesses, Windows 11 is the clear choice. It offers improved security, faster performance, and better tools for multitasking and collaboration. It’s built for modern workplaces and supports a wide range of productivity software.
However, not all PCs will meet the requirements for Windows 11. Older devices may fall short in terms of processor type, system firmware, or TPM compatibility. If your device doesn’t qualify, there are still good options available.
Some users may consider switching to Linux for a lightweight, customisable environment. Others might explore Mac if their work leans toward design or creative tasks. ChromeOS can also be useful for simple, cloud-based workflows.
Cloud solutions like Windows 365 and Azure Virtual Desktop let you access your system remotely without needing powerful hardware on-site. These platforms are flexible and work well for remote teams or mobile setups.
Common Challenges and Mistakes to Avoid
Upgrading your systems can go smoothly if you steer clear of these frequent slip-ups:
- Delaying the upgrade until support ends can lead to rushed decisions and unnecessary downtime.
- Upgrading hardware that isn’t compatible wastes time and money—always check requirements first.
- Skipping backups puts your data at risk if something goes wrong during the switch.
- Not preparing your staff for a new system can cause confusion and slow productivity.
- Forgetting to check third-party software compatibility may leave you stuck with apps that no longer work.
Why Upgrading Is the Smart Move
Upgrading may seem like a big expense upfront, but sticking with unsupported systems could cost more in the long run. A single security breach or extended downtime can hit harder than the price of new hardware.
Newer systems bring faster performance, lower power usage, and fewer ongoing support issues. You’ll also spend less time fixing glitches and more time getting work done.
Modern tools offer smoother workflows, better collaboration, and a more user-friendly experience. The result? A more efficient team and fewer headaches—proof that upgrading is an investment, not just another IT cost.
How IT Support Makes It Easier
Navigating system upgrades can be stressful, especially if you’re trying to manage it in-house. Working with a trusted IT provider takes the pressure off and helps things run smoothly.
Professionals can offer tailored advice based on your industry, goals, and setup—no guesswork, just what works best for you. You’ll also reduce downtime with a clear upgrade plan and backup strategy.
The support doesn’t stop once the new system is live. Ongoing assistance ensures your team stays productive, secure, and confident using the updated tech. It’s expert help without the hassle of doing it alone.
