Microsoft recently released a significant update for Windows 11 that is highly relevant for both businesses and home users. Version 25H2 introduces a new security requirement aimed at preventing the use of systems with duplicate computer SIDs (Security Identifiers). This change could lead to significant challenges, particularly for clone installations, as such systems will no longer be able to be successfully authenticated in the future.
The introduction of this security measure is a crucial step in preventing unauthorized access to sensitive data. In the past, it was possible to access network drives or remote desktop connections by cloning Windows installations. With the new regulation, this is now prevented, which significantly strengthens security in company networks. Therefore, Microsoft recommends using the Sysprep tool when creating or cloning Windows installations to ensure that each installation receives a unique SID.
Some problems may arise for users who have already switched to Windows 11 25H2 or are using cloned systems. These include repeated login prompts despite correct credentials, error messages such as ‘Login failed’ or ‘Your credentials didn’t work’, as well as loss of access to shared network folders or remote desktop sessions. Errors such as ‘Access denied’ can also occur during failover clustering, highlighting the need to be aware of new security requirements.
Microsoft’s decision to introduce this security change is part of a broader trend to increase the security of operating systems and ensure the protection of sensitive data. This is particularly important at a time when cyberattacks are becoming increasingly sophisticated and companies are increasingly reliant on digital infrastructure. The use of Sysprep is therefore not only mandatory, but also an important tool for maintaining the integrity of IT systems.
Overall, it shows that Microsoft is making an important contribution to data security with the new security requirements. IT administrators and power users should be aware of the changes and adjust their installation processes accordingly. The long-term benefits of this measure could be significant as it helps increase the security and reliability of Windows-based systems.
