Before you install Windows, use this tool to see if it's genuine or pirated.
The Windows and Office Genuine ISO Verifier tool is a portable and small tool that can verify all Windows versions up to Windows XP and Windows Server 98. It can also check all Office versions. The tool can be downloaded using the link provided below the post. After unzipping, launch it and click the three-dots button opposite the Input File field. A window will appear, allowing you to navigate to the folder containing the ISO file you want to verify and select it, whether it is for the Windows or Office version. Then, click the Open button to select it.
Then click the "Verify" button and wait for the verification process to complete (approximately one minute). You must be connected to the internet for the tool to analyze the ISO file and extract its hash code. The tool will then compare this hash code with the official Microsoft hash code and display the result.
If the copy is fake, the result will be "Not Genuine" in red.
If the version is genuine and downloaded from an official source, the result will appear in green as "Genuine."
If you have the hash code, you can enter it in the designated field, and it will be checked automatically without needing the file.
