vs "Not found and constrained"

Recently I was really anxious to get angry Ah, installed SQL Server for a few days, the last is to reinstall the system, installed SQL Server, and re-installed VS, but the new project is always unsuccessful. The problem is as follows:

Online search, said is the update caused by the patch, then since the update has patches, why always let updates ah. I was installed yesterday vs, yesterday evening also knocked the example, this morning came up, the boot began to constantly update, so first don't let him update.

1.

Tools--Options--Extensions and updates--tick out the automatically checked updates.

2.1

To delete an updated file

In the Control Panel--click on "View installed Updates" On the left--find the content below, then delete.

2.2

If the update does not have the two files above, then the file should be deleted? Since it is a patch, then download a patch of the tool installed on it, to recommend the site:

Download this update package and install it to solve the problem.    Sometime, then let me grind it more!!
