Why did the calendar in my computer suddenly change?

After searching for two days, I finally found this thing. It's really good. You can use it safely. Even if there is a virus, it is not the problem of this calendar. If you think the computer is slow, you can kill some Trojans that antivirus software can't find, and the effect is good. It feels like an advertisement. Ha ha laugh

Actually, I think this is good. I'm still trying to figure out how to make my computer like this. Your CPU is 100%. That's another question, which has nothing to do with this clock. My computer also has this, but later I reinstalled the system and tried to get it back, but I couldn't find it. It is said that it is an official clock, but it is actually another one found online, which is different from this one; My conclusion is that there is nothing wrong with this clock. Please feel free to use. If you know its origin, please send me the next one. rose265 1@ 126.com

Some people say that he deleted wintime in the Add and Remove program in the control panel, but it is not. If you really doubt that this thing is not good, you can try it.
