The eula gives permission to the MS managers to use YOUR computer as a file-sharing server. Updates can be uploaded from your machine to other machines.
The eula gives permission to actually remove software, and other files, deemed to possess the potential to affect the performance of any MS product.
Logging into YOUR computer with a MS account, increases the likelihood of all this happening. Because using an MS account is equivalent to using any network login, which is subject to all the rules established by the server administrators. At which time YOUR computer is effectively a client machine that is in nearly complete control by those rules.
The eula gives permission to track/copy your browser use, use of Skype (including your voice print), Cortana, maps, and any documents opened by MS software, for the stated purpose of learning how to make MS software more "useful."
This means, MS managers have all the data needed to locate YOUR computer within feet of its actual location.
Per the eula, MS will comply with an policing agency that can show reasonable cause to provide all said data. If in the opinion of MS managers, with guidance by such agencies, you have something on YOUR computer that is deemed illegal, YOUR computer, and yourself, can be confiscated. Even if you are unknowingly participating as in having been infected by a web bot.
And: auto updates' default is to restart the computer when not in use. Does this mean a "forced" restart as the MS dudes do not think all the programs and files I have open, though saved, can be closed without my permission?
And when happens when an update is bad, as already happened with at least four updates, from MS, that puts the computer into an endless loop? When I have to get work done now, not after spending hours fixing what should not have happened.
Updates are fine when I choose to install them based upon my needs.
Windows 10 works great. It is all the other stuff that everyone should be resisting. That too many are not is extremely worrisome.
