Cannot get rid of water mark saying activate windows

Hello, I have this computer for four years now and this is the first time the water mark activate my windows show up. It will be gone after restart but will come back eventually. Pleae help.

 

Water Mark???

What happened to the Win10 water mark? I was receiving updates for Win10 preview Insider build fast mode. All of a sudden I'm back to Win10 Pro. I never changed it. The water mark was in the lower right corner. I reset it back to get insider builds but
still no water mark. This water mark came in handy to see what version/build I was on and also to know what HDD I am on as I duel boot from Win10 Insider to Win10 Pro.

 

activate windows water mark since end of setpember

I have purchased this custom computer at the start of the summer in 2017 and had no problems with it until September that same year and have noticed

a water mark that says activate windows on it and ignored it hoping it may fix in the next up coming updates but it haven't and is starting to irritate me because when using shadow play to stream cs-go it flashes very quickly on stream which is not the best

example cant down size sorry
