Ok, on to Bing to search out for possible solutions since all of these systems were working last Friday. So, I grabbed my Windows 8.1 laptop (yes, I have many many devices to test with). Again, not what I wanted to deal with on a Monday morning. I grabbed my Surface Pro 2 (also running Windows 8.1 Update)… Same issue. Ok, no worries, I have other systems I can use to troubleshoot with. Not exactly what I wanted to deal with on a Monday morning. Windows Key, all individual characters function keys, etc. I sat down and logged in as usual, however, once at my Windows 8.1 Update desktop, the keyboard stopped working. This morning I came into my office to find myself with a lovely little surprise.
