I changed my mind.
I was on the fence about installing it, and was considering yesterday. However I did some more research and read some new to me information today and decided not to. First reason was that I heard that there are problems with getting the Cisco VPN to work. I have to have that to remote on to work to fix problems. The other are privacy issues. Microsoft stores your private bitlocker key on onedrive if you have that running, and the other is that they reserve the right to have carte-blanche access to everything on your machine. “We will access, disclose and preserve personal data, including your content (such as the content of your emails, other private communications or files in private folders), when we have a good faith belief that doing so is necessary to”, for example, “protect their customers” or “enforce the terms governing the use of the services”. I uninstalled and blocked the KB3035583 update from the 3 machines that were candidates.
