I received the update earlier today, which took just over an hour to download and install.
One thing that really bugs me with every big update is that it breaks a driver on at least one PC I update. For example, the last fall update led to no sound on my workplace PC as it replaced the MaxSound driver with a generic Microsoft audio driver. It took a while to try to find the proper driver to get it working again as it did not provide the option to revert the driver.
This time on my home PC all seemed fine until I noticed my Internet connection was unusually slow. I ran a few speed tests and got about 2Mbps each time. When I tested on my mobile, I got about 30Mbps, which is what I typically get. I rebooted the PC, tried reconnecting the Wi-Fi, etc. but no improvement. Then it hit me that it might have replaced the driver and sure enough it replaced the TP-Link driver with a generic Microsoft WLAN driver. I reinstalled the TP-Link driver and the Internet speed was back to normal again.
As usual, this update re-enabled the “Fast start-up”. I always turn this off as the benefit is minimal with an SSD. On the other hand, I think this is the first time it didn’t reset my file extensions, e.g. music & video clips still open with VLC, PDFs with PDF exchange, etc. The only minor issue was JPEG files wouldn’t open at first as Microsoft finally got rid of the former Windows 7 style picture viewer, which I had associated with JPEG files.
