WINDOWS 10: WHAT TO DO WITHOUT SUPPORT
The end of support for Windows 10 is approaching relentlessly – on October 14, 2025, Microsoft will finally end free updates for the operating system. For many private users, businesses, and organizations, the question arises: What to do after the end of Windows 10 support?
Is switching to Windows 11 necessary? Are there alternatives to Windows? What about security after the official lifecycle of Windows 10 ends? In this comprehensive blog article, you will find all relevant information, tips, and options so that you can make the best decision for yourself after Windows 10 support ends.
The end of support for Windows 10: What does it mean?
Microsoft defined the lifecycle of Windows 10 years ago. On October 14, 2025 (after ten years), free updates, bug fixes, and new features will officially end. After this date, Windows 10 will no longer receive important security updates. The operating system will still function as usual, but the risks in everyday use will increase – especially if the computer is connected to the internet.
What changes starting October 14, 2025?
- No more free security updates
- No new features or bug fixes
- Increased risk due to security vulnerabilities
- No compatibility guarantee for new programs and devices
This is a significant change for private users, freelancers, and businesses. Continued use of Windows 10 after support ends is not recommended from an IT security perspective – however, there are alternatives and options that we will discuss below.
What risks exist after Windows 10 support ends?
Those who continue using Windows 10 after October 2025 take on significant security risks. After the end of support, newly discovered system vulnerabilities will no longer be patched. Cybercriminals could specifically target systems that are no longer protected by up-to-date security updates.
Specifically, the risks include:
- Viruses, trojans, and other malware can more easily penetrate
- Ransomware attacks become more likely
- Data loss and data theft are possible
- Loss of insurance coverage in case of data breaches (especially for businesses)
The Federal Office for Information Security (BSI) explicitly warns against continuing to use Windows 10 after the official support end – especially in authorities, businesses, or on computers processing sensitive data.
What options do I have after Windows 10 support ends?
Fortunately, there are several ways to continue after Windows 10 support ends. The best solution for you depends primarily on your hardware, your requirements, and your need for security.
1. Switch to Windows 11
For many users, switching to Windows 11 is the obvious option. Microsoft offers Windows 11 as the successor to Windows 10 and continues to guarantee updates and new features.
Advantages:
- Modern operating system with current security protection
- Familiar interface with new features
- Support for current software and hardware
Important:
Not every PC with Windows 10 can easily upgrade to Windows 11. Microsoft has significantly raised the system requirements:
- Processor: At least 1 GHz, 2 cores, 64-bit compatible, on supported CPU list
- RAM: At least 4 GB
- Storage: At least 64 GB
- TPM 2.0 (Trusted Platform Module) and Secure Boot required
It’s best to check with Microsoft’s free PC Health Check Tool whether your device is compatible with Windows 11.
2. Paid security updates (ESU) for Windows 10
After support ends, Microsoft offers so-called Extended Security Updates (ESU). These allow you to continue receiving important security updates for a limited period – but at a cost.
Details about ESU:
- Available from early 2025 (expected at around €50–70 per year for private users)
- Duration: until October 2028 (maximum three-year extension)
- Annual price increases possible
- Only critical security updates will be provided, no new features or bug fixes
3. Switch to an alternative operating system (e.g., Linux)
Those who don’t have a compatible PC for Windows 11 or are deliberately seeking alternatives can switch to Linux. Modern Linux distributions such as Ubuntu, Linux Mint, or Zorin OS are easy to use and well-suited for many everyday tasks.
Advantages of Linux as a Windows alternative:
- Free and open source
- Usually lower system requirements than Windows 11
- Broad support for office, internet, and multimedia
- Many programs work via open-source alternatives or with Wine/Proton
Note:
Certain Windows programs and specific games may not run on Linux. Therefore, check beforehand which programs you really need and whether they work under Linux.
4. Continue using Windows 10 offline
For very specific use cases – such as playing old games or working on a computer without internet access – Windows 10 can still be used after support ends. It is important that the PC has no internet access and, if possible, no data exchange via USB sticks or external hard drives.
But be careful:
Even offline, there is a residual risk from imported malware or security vulnerabilities in old programs. This option should only be considered in exceptional cases.
What must businesses and authorities consider?
For companies, authorities, and organizations, the end of Windows 10 support is particularly critical. The BSI clearly recommends starting to plan the migration to Windows 11 or alternatives now. Delaying the switch risks not only IT security but also legal issues and possible fines in the event of a data breach.
What businesses should do now:
- Inventory all Windows 10 devices in use
- Check whether hardware supports Windows 11
- Develop a migration strategy and set a timeline
- Set up test environments for Windows 11 and/or Linux
- Train employees and support the transition
- Plan timelines, costs, and resources for Extended Security Updates
Especially for companies, ESU license costs increase annually. Switching to Windows 11 or an alternative operating system in time is often more economical and secure.
Step-by-step: What should you do now?
To respond safely and stress-free to the end of Windows 10 support, the following steps are recommended:
- Check your hardware: Use the PC Health Check Tool to test Windows 11 compatibility.
- Create a backup: Save all important data to an external hard drive or cloud storage.
- Decide on an option: Switch to Windows 11, use ESU, move to Linux, or continue using offline.
- Inform yourself about the chosen solution: Read guides, forums, and tutorials to prepare for the switch.
- Plan the transition: Especially companies should create a timeline and budget.
- Carry out the transition: Install the new operating system or purchase ESU updates in time.
- Test the new system: Check whether all programs and devices work as expected.
Questions and answers about the Windows 10 support end
Can I upgrade to Windows 11 for free?
For many users, upgrading to Windows 11 is still free if the hardware is compatible and a valid Windows 10 license is available. Microsoft has not yet announced any fees for the switch. However, note: On unsupported hardware, the upgrade does not officially work. Unofficial installations are possible but not recommended, as you will not receive support or all updates.
Is Windows 10 still secure after support ends?
No, after October 14, 2025, there will be no more free security updates. The operating system becomes more insecure with each passing day, as newly discovered vulnerabilities will no longer be patched. Only with Extended Security Updates (ESU) will you receive important updates for up to three more years – but at a cost. Using Windows 10 without current security updates is no longer safe, especially if connected to the internet.
How can I continue receiving updates for Windows 10?
After the official support ends, Microsoft will no longer provide free updates. However, with the purchase of Extended Security Updates (ESU), you can continue receiving important security updates – until October 2028 at the latest. Private users will likely be able to purchase these updates directly from Microsoft, while companies can obtain them through specialized partners. Prices will increase each year.
Can I continue using my old PC with Windows 10?
Technically, Windows 10 will continue to work after support ends. The biggest risk, however, is becoming vulnerable to malware without security updates. For PCs used offline, the risk is lower – but not zero. For internet-connected PCs, switching to Windows 11 or an alternative OS is strongly recommended.
What alternatives to Windows 11 are there?
Linux is the most popular alternative. Modern distributions like Ubuntu, Linux Mint, or Zorin OS are relatively easy to install and suitable for many everyday tasks such as browsing, office work, or media playback. Older PCs that are incompatible with Windows 11 often benefit from Linux. However, for specific programs or games that only run on Windows, Linux may not always be the best choice.
What happens to my programs and files when switching?
When upgrading to Windows 11, programs and files are usually retained. When switching to Linux or performing a clean installation, you should back up all data in advance and check which programs work on the new system or need to be replaced.
Conclusion: Take action now and start safely into the future
The end of Windows 10 support on October 14, 2025, is a significant turning point for all Windows users. Anyone who wants to continue working securely on their PC should inform themselves in good time and take action. Switching to Windows 11 is the simplest path for many – if the hardware is compatible. With Extended Security Updates, the lifetime of Windows 10 can be extended – but at increasing costs and without new features.
For older PCs or those seeking alternatives, Linux is worth considering. Businesses and authorities should develop a migration strategy early to avoid legal and security risks.
Don’t wait until the last moment! Check your options, back up your data, and make the right decision for the post-Windows 10 era.
