I am use windows server 2003 and install dns and domain
After a Windows update show me when open the Internet browser LOOKING UP Google "my home page google"
And some time open

Open Internet Explorer. Locate & right-click on Tools then Internet Options. This will open a new panel. Find Home Page & change the setting to your preference. Personally, I always select "blank page" to keep other "stuff" for appearing. You may may find your previous home page & select it.
If all else fails, any time Microsoft updates your OS, they also install a "Uninstall" file which can be executed to revert the system to just before the update. It is located within the Windows directory.
