When you buy a new PC they are loaded with what is termed Bloatware, sort of not so useful software that just add to the time it takes for the PC to boot up, they consume resources be being resident in memory and because they are installed the use up hard drive space.
I am surprised that the person setting up your PC did not remove these unnecessary items of software as for Chrome that is a terrible thing to install, it is the worst browser, it clogs up your computer, installs addons that are not needed and can even install additional security products that again clog up your PC. This is what is happening with the MSN pop up, so get your PC guy to remove it, to use Ccleaner to remove all traces of Chrome and Bloatware and to cleanup the Registry. If the guy says anything to the contrary, find another PC guy as this one knows diddly squat.
As has been said Apache will open your Word docs the problem being the File Association defaults to office products and whilst the Open With method works it is not a permanent solution.
Using File Explorer navigate to one of your Word Documents, a single left click on it to select it then right click for the pop up menu, in this menu select Properties.
Once the Properties Window opens you will see Open With displayed together with which programme is the default one it uses.
From the adjacent drop down menu select Open With then choose Apache, then click on Apply at the bottom right.
Then Apache will be the default programme.
Do the same for Excel Documents.
Again this is what your so called PC guy should have done.
I have been two days cleaning up a friends Laptop after he made a complete hash of it with software and failed updates.
