I am not saying that I have done so, but let's say that I keep copies of some older .exe files 'because'. Now that I read this I laughed a bit because those will come in handy.
Also I always suggest that you find WindowsFirewallControl v4.9.x.x and install it, and set it on "Medium Filtering" and "Display Notifications". They block all the garbage MS bloatware apps that want to 'speak to the internet' and trust me when I tell you, 99% of the apps in your PC don't need to have 24/7/365 access. You want to update your VLC? Good! Allow it for 5mins, update, block it again. Same for the myriad other Microsoft .exe files that do not serve OUR purpose.
