If you are looking for a gaming-optimized version of Windows 10 Pro:
The number 190452130 is likely an error. The reference to Windows 1 might be a nostalgic skin or a misunderstanding.
The biggest danger is the source. These ISOs are usually distributed via torrents or file-hosting sites. There is a non-zero chance that the uploader has embedded a keylogger, cryptominer, or trojan into the OS image.
Mentioning Windows 1 is odd. Windows 1.0 was released in 1985 and is completely obsolete. This likely refers to a “Windows 1” theme or a “new” custom interface that mimics the vintage Windows 1 look but runs on Windows 10 Pro.
Alternatively, it could be SEO spam—combining old and new keywords to attract clicks.
Because official security updates are often disabled or stripped out to save resources, your PC may be vulnerable to malware and ransomware. If the OS is built on an older version of 19045 without the latest cumulative patches, you are leaving your system open to attacks.
