What happens if Win7 is not activated?

Win7 can be activated without activation? What happens if Win7 is not activated?

First of all, when starting the computer, this window will appear before entering the desktop:

If you choose to cancel or slightly After asking me, the following window will appear:

After you click OK, you will enter the desktop. There is a non-genuine prompt in the lower right corner of the desktop, and the desktop is black.

Of course, although the desktop can be set, as shown in the figure, after a while, the desktop automatically becomes a black screen again.

Then try online update, when I choose Windows Update, I am prompted to be a pirate victim:

However, it seems that the update is not affected:

That is, no Activation can also be used, which is quite kind compared to other software that pops up ads.

Since it doesn't affect the use, if it can't be activated, it's okay. ……

The black screen is black. I think the desktop is quite personal. Occasionally pop-ups indicate that I am victimized. And so on, it can still be accepted.
