Disable Trial Copy Watermark in Windows Insider Preview
If you’re using Insider Preview for Windows 10 , you might be annoyed by the small watermark that appears in the lower-right corner of your desktop. This handy little utility will get rid of it.
This watermark can be useful (as it shows you which build you are using), but if you don’t want to see it anymore, just download the Universal Watermark Disabler below, run it and click Install. (We recommend that you back up before doing this, as this changes the system files.) This will log out and log back in, and the watermark should be gone.
To get it back, just run the utility again and click Uninstall.
