"Windows 10 still powers numerous PCs" - A changeless fact for many personal computers (PCs) is that they continue to run on the Windows 10 operating system.
As the end of support for Windows 10 approaches on October 14, 2025, German PC users face an elevated risk of security vulnerabilities, lack of technical support, and potential software incompatibility.
Without security updates, Windows 10 systems become more exposed to malware, ransomware, and cyberattacks, making user data and system integrity more vulnerable. Users will also no longer receive bug fixes or feature updates, causing eventual software malfunctions and loss of compatibility with newer applications. Microsoft will no longer provide technical assistance, and older hardware may face driver support issues as well [1][2][3][4].
Post-End-of-Support Consequences
After the end of support date, several consequences will be felt:
- No new security patches: Leaving systems open to exploits and attacks that target unpatched vulnerabilities.
- No technical support: Microsoft will not help resolve issues affecting Windows 10 systems.
- Software and hardware compatibility issues: Developers will focus on Windows 11, and some apps or drivers may stop working properly or updating on Windows 10.
- Increased risk of productivity loss: Due to malware infections or system failures, especially for business users relying on Windows 10.
- Limited extended security updates (ESU): Consumers can buy limited ESU for about a year, but this is a temporary bridge, not a long-term solution [1][2][3].
Upgrade Options and Challenges
Microsoft encourages users to upgrade to Windows 11 or acquire new hardware compatible with it. However, some users may face challenges because Windows 11 runs best on newer devices with features like Neural Processing Units (NPUs), potentially requiring hardware upgrades to fully benefit from the latest OS [1].
The Need for Action
Alexander Opel, an IT security expert at Eset, warns that continuing to use an outdated operating system is risky, likening it to playing Russian roulette with data. He advises against purchasing Extended Security Updates, stating that it only delays the upgrade to the near future and could be financially irresponsible for many organizations [1].
According to Opel, it's high time for companies to perform an upgrade due to the potential costs of support outweighing the benefit for many organizations and the risk of successful cyberattacks on outdated systems.
Current Scenario in Germany
As of now, approximately 24.7 million computers in Germany still run on Windows 10, which corresponds to around 57% of all Windows computers. Among these, 17.9 million PCs have already installed Windows 11, an increase of eight percent since November 2024. Microsoft offers private users and commercial customers an additional year of Extended Security Updates (ESU) for $30 (around 27 euros) as an option for those refusing to upgrade to Windows 11 [1].
The Way Forward
The Federal Office for Information Security (BSI) recommends switching to alternative operating systems such as macOS for Apple Macintosh computers or the free Linux system in addition to a timely upgrade to Windows 11. Manufacturers are trying to clear their excess inventory due to ongoing uncertainties and potential new tariffs, making it a good time for users to consider purchasing new hardware that meets the requirements for Windows 11 or other modern operating systems [2].

- In the absence of regular security updates, Windows 10 systems may become easier targets for cyberattacks, putting user data and system integrity at risk.
- As developers focus on Window 11, software and hardware compatibility issues could pose a challenge for continued use of Windows 10, particularly after the end-of-support date on October 14, 2025.
