First of all, as I posted ages ago, a Microsloth employee actually said the assumption that WaasMedic was an update repair tool was false despite its "Properties" description. The clear implication is that it is actually designed to do something MS does NOT want you to figure out. On my system it did not restrict itself to perusing update file directories; it always read EVERY FILE IN MY UID after going through the system files. Since I have over 20,000 photos plus "side-car" files for each from various photo processing applications, WaasMedic would run for over an hour making the machine unusable for 40 to 90 mins after boot. Clearly, despite all my privacy settings, MS was building a detailed profile of my system but for what purpose?
Since the trend since Windows XP has been to reduce user-confgurability, force the user to give up more system control directly to Microsloth, cede more privacy rights to MS, and trick users to connect directly with MS servers (SkyDrive, OneDrive, Office / Microsoft 365, MS account to install / activate) if possible, for the entire time the system is powered up, the assumption that Windows will become a subscription service is probably a very good one. The point is the <removed> they have users by are the ones users unwittingly handed to them by letting slide all the privacy violations, monopolistic unfair business practices, and flat out lying they have done with impunity (WaasMedic being a prime example).
I only escaped WaasMedic impacts with the installation of an SSD about two weeks ago. My experience seems to confirm that WaasMedic on an SSD surveys VERY FEW files on a boot drive hosted on SSD. I cannot get Task Manager / Resource Monitor up fast enough to even catch it running. But still, to be safe, I moved "Documents", "Pictures", "Music" and "Videos" to the hard drive that used to be to boot volume. Now along with two separate RAID volumes, WaasMedic does not seem to access any personal files anymore.
So why would MS want us all on SSDs? Simple. They can mega-load the OS with spyware, marketware, MS Store apps all of which auto-start at boot time, yet users will not be "bothered" by the 30-secs to 1 minute SSD boot-up time. Purpose of all the fatware? To be able to capture your every keystroke, screen state, app activation, media file usage etc. etc. IOW, to have full-time, all-action surveillance of your system usage logged on their servers. The excuse? "Microsoft has innovated Windows to the first cloud-based Operating System, so like any other utility it needs to fully monitor usage for proper QoS to give its users the best experience." (Putting on waders as the MS BS is getting so deep.)
The government will not do its job and break-up or stand up to the monopoly. So, there is only one choice - Linux.
