Denied by Default

I recently installed a fancy new firewall for a client.  Out of the box, the web filtering policies are blocking the installation of Office 365 apps from Microsoft. Curious, yes.  The category responsible for blocking is Risky Downloads .  Installing Office Apps? Risky, indeed. I had to add a Web Protection Exception with the following entries: ^([A-Za-z0-9.-]*\.)?microsoft\.com/ ^([A-Za-z0-9.-]*\.)?windowsupdate\.com/ ^([A-Za-z0-9.-]*\.)?officecdn.microsoft.com.edgesuite.net/ ^([A-Za-z0-9.-]*\.)?officecdn.microsoft\.com/ ^([A-Za-z0-9.-]*\.)?windows\.com/ What a wonky syntax.  Can you guess what the firewall vendor is?

Selective Screenshot Whaaa?!

So, I was today years old when I learned that there's an easy way to do a screen snip in Windows 10!   All along, I had been hitting PrtSc and then pasting the result into Paint, and then cropping the image to select the portion I wanted. No more! Simply hit Win-Shift-S on your keyboard. (Hold the Windows key, hold Shift, and press the letter S, all at the same time.) Your screen will dim, and you can use your mouse to drag and select the area you want. There are also some fun options that appear:  Freeform Snip, Window Snip, and Full Screen Snip. Enjoy!
