How to judge whether the Win10 system is genuine from the watermark?

The Win10 system is mainly divided into two categories: preview version and official version. The preview version is mainly used for testing, so the update speed is very fast, resulting in a lot of system versions. This also makes some pirated Win10 mixed in, it is difficult for users to distinguish between true and false. The following small series will tell you a trick, teach you to judge whether the Win10 system is genuine from the watermark.
Win10 official version of watermark style is not activated

Win10 watermark is generally divided into two categories, one is the preview version of the watermark, fixed in the lower right corner of the desktop, the format is not unique, which is related to the nature of the version (as shown below) . The other is the pirated watermark, which is the new variety in Win10. From the style point of view, this is called the real watermark: semi-transparent font, always displayed at the front (as shown above).

For the Win10 preview watermark, since it does not always show up, it only plays the role of version mark, so it has little effect on the normal use of the user.

For the recent changes to the watermark format of each version of Win10 RS1 Preview 11082, you need to clarify: these versions have watermarks, and the format is the same, these versions are not pirated, but Microsoft changed Watermark format and content only.
Win10 is not activated. The watermark is always displayed at the front.

For the inactive watermark, there is currently only one format. This kind of watermark font is large, and can be placed on the front end display, which affects normal use, because it is really "unsightly". To get rid of it, you have to activate the system early. The activation method is relatively simple. You can purchase a new Win10 product key or activate it with your existing Win7/Win8.1 key.
You can directly purchase the app store in the system activation interface

So, if there is a watermark, if you want to see if Win10 is pirated by watermark, whether it is activated or not, you can directly judge it by looking at the existing watermark type. : The font size is large, the translucent top shows the pirated (inactive) watermark; the white small character in the lower right corner of the desktop is the Win10 preview watermark, no need to worry.

It is important to note that the Win10 system without a watermark is not necessarily genuine. If there is no watermark, it is not necessarily pirated. If your Win10 system has a watermark and you have determined that your Win10 system is genuine, you can also use some methods to remove the watermark.
