You can safely update the Windows Patch.

Some time ago, we had a lot of trouble. Several of our colleagues' home machines were updated due to Windows patches.ProgramAnd the system is locked. I haven't updated it for a long time. This time, on the update and Download notification, I suddenly noticed the following prompt:

The size is 1.2 MB.

The Windows Genuine Advantage notification tool notifies you whether your windows copy is genuine. If you find that your system is not genuine, this tool will help you obtain a copy of the Windows License.

Can I find more information about this update http://go.microsoft.com/fwlink/ at the link below? Linkid = 39157

In fact, as long as you carefully check the prompts before downloading the updates, you can cancel the dangerous ones. All the software is the same. We can see the instructions carefully before clicking "Next" quickly, so that we will not encounter any problems beyond our expectation.
