Why Windows Activation Matters:
Security Updates: Many compliance frameworks require systems to be patched and updated in a timely manner. If Windows is not activated, it may not receive security patches, which could lead to non-compliance.

Licensed Software: Compliance frameworks emphasize the use of authorized and licensed software to prevent the use of pirated or counterfeit software, which can introduce vulnerabilities.

Full Security Features: Some compliance controls require the use of full security features (e.g., BitLocker, Windows Defender). Non-activated Windows systems may disable or restrict access to certain security features, leading to non-compliance.
