KMSOffline v2.4.5 (and its more recent version, v2.4.7) is a product created by the renowned Russian developer Ratiborus.

KMSOffline is a popular one-click activation tool developed by Ratiborus that emulates a Key Management Service (KMS) to activate Windows and Microsoft Office products. Preparation

Before using any tool like KMSOffline, you must understand the significant risks involved. Many activation tools are classified by antivirus programs as potentially unwanted programs (PUP) or "HackTool," which is a technical flag for software that modifies system behavior. While this is often due to the nature of the software's modifications, it is also a common disguise for genuine malware. Experts warn that "90% of the activation tools you find on search engines are bundled with dormant cryptominers or browser hijackers".

Microsoft Defender will almost certainly flag this tool as HackTool:Win32/AutoKMS . While this is technically a "potentially unwanted program" (PUP) rather than a virus, the distinction is small. The tool is hacking the licensing system. KMSOffline v2.4.5 -Windows and Office Activator...

KMSOffline v2.4.5 is a technically sophisticated but legally and ethically problematic tool. It exploits the trust-based KMS protocol by mimicking a legitimate activation server locally. While it successfully activates Microsoft products offline for 180-day cycles, the risks of malware integration, system instability, and legal non-compliance outweigh the cost savings.

If you have already used KMSOffline or similar tools, run a full offline scan with Windows Defender Offline or a trusted second-opinion scanner like Malwarebytes. Then, consider performing a clean Windows reinstall to ensure all backdoors are removed.

Based on community documentation, KMSOffline v2.4.5 is reported to support:

Unlike older activators that failed on Windows 10/11 Home (which doesn't officially support KMS), KMSOffline v2.4.5 uses workarounds to inject the necessary KMS client keys into Home editions, converting them temporarily to a volume licensing channel.
