As of May 2025, the PXIe-8881 and the PXIe-88x2 embedded controllers are the only NI PXIe embedded controllers that fully support Windows 11. However not all of the controllers within these models support Windows 11. According to the Microsoft support guidelines, TPM 2.0 is required to run Windows 11, as an important building block for security-related features. So, only our PXIe-8881 and the PXIe-88x2 family controllers that come with TPM 2.0 are able to host Windows 11 OS.
All other NI embedded controllers don't fulfill the minimum system requirements to support Windows 11. NI cannot support installing Windows 11 on other NI PXIe embedded controllers.
