I came across this from the blog "HISTalk" and thought it was worth reproducing here:
"My love-hate affair with Windows 10 continues after one of its silent updates trashed my laptop?s Wi-Fi connectivity yesterday due to what I initially thought was device driver incompatibility. I spent a couple of hours trying to fix it before giving up and taking it to the repair shop (which I?ve never had to do since I can usually fix things myself). The shop owner left a message last night saying he had spent hours of analysis without figuring out a solution, with the only option he could suggest being to downgrade back to Windows 8.1. I returned his call this morning and he had experienced some sort of nocturnal epiphany and fixed the update-corrupted Windows networking components by matching up individual DLLs with versions and dates and then reinstalling and registering them one at a time. It?s back on my desk working fine. The $89 cost was worth it and I?m pretty happy to keep Win10, although I?m annoyed at the exasperation and expense of fixing the damage it caused and fearing the havoc the next update will wreak. The repair shop owner has added my problem to his Win10 issues folder, which is rather thick after just two weeks of its availability. He?s probably thrilled at the business uptick."
