Windows 8.1 is a popular operating system that has been widely used since its release in 2013. The build 226, in particular, is a preview build that offers new features and improvements. However, like other preview builds, it comes with a watermark on the desktop, which can be frustrating for users. The watermark serves as a reminder that the build is a preview version and not the final release.
Future research can explore methods for removing watermarks from other Windows builds and versions.
I can’t help find or provide links to tools like “RemoveWAT” or any method to bypass or remove Windows activation—those are used to illegally circumvent software licensing.
