That is to stop people from disabling W10's telemetry, spyware, adware, data mining, turning on your microphone/camera, etc.
I swear, for the high level of spying, telemetry, & data mining in Windows 10, they must have been paid by the NSA, CIA, or something. It's most certainly NOT very secure in any way. You don't see high level government officials, scientists, & NASA using that crap, golly many of them are still using XP. And they're trying to dump that garbage onto other versions of windows too.
People been disabling all that crap only to find it is re-enabled by the next windows 10 update. So there was a community that was checking the updates, so we can block the offending ones. By putting them in a single bundle, they stop people from blocking their offending updates.
Since they started to force people to upgrade to W10, & install nagware to constantly harass you to upgrade, many people have just cut off updates entirely, except for their third party security like antivirus, their browser updates, or driver updates directly from their hardware manufacturer.
Then they started downloading W10 into people's machines without their knowledge, while installing a lot of the same telemetry, spyware, & data mining that's in W10 into W7 & W8 machines through their updates.
All my machines are running W7 & Linux in dual-boot except for an old laptop which I downgraded from W7 to a commercial & military version XP that is supported until 2019.
I have had all windows updates disabled since the end of January because it became too much to bother with anymore. Their updates were constantly trying to convert my machines into something I don't want, & dump garbage into them. It just got to be too much of a pain to keep track of which updates I want, & which to block. And the ones I blocked would become mysteriously unblocked the next month, or replaced by another update just as bad. How dare they meddle in my computer, & unblock items that I made a decision to block for very good reasons.
With no more windows updates, I haven't got any viruses, malware, & haven't been hacked. I do tread in some more dangerous territory than an average user, & test all sorts of strange software, even some that I know had embedded malware. No problem! There are a few experts out there who insist they don't need any microsoft updates ever.
My newer "used" laptop is running a version of windows 7 with updates in it no newer than December 2014. It's running excellent, safe, & secure, without a hitch. It's more secure than any Windows 10 machine, android, or iphone. I may never get new windows updates for it. Browsers & antivirus are up to date though. Even those aren't on auto-update. I update them about every month or 2, & I'm fine.
I have Linux Distro Astro on it too, for dual boot. I've started a new habit with Linux too. No updates. It pisses me off after I spent days or weeks getting a Linux version I actually like, & getting it to work the way I want it to, that after a Linux update, it's broken or all phucked up again.
I used to be a Linux Zorin fan. But with updates, or their new versions, it's nowhere near as great as it used to be. Why do software writers insist on taking something great, that everybody loves, & screw it up just for the sake of a new upgrade or update? I see IT critics whine about software that hasn't been updated in a year or 2. Well, if the software runs great, & everybody likes it, why the hell would any sensible person decide to change & update it for no good reason?
Firefox used to be the best browser in the world for years when it got updated about twice a year. Now with updates every week or 2, it's become bloatware.
Everybody's become update/upgrade crazy. Here's a lesson I learned way back in the mid 1990s: Every Windows update would break something, slow the machine down more, & I'd lose something or some feature I really liked.
Can you imagine artists going into the art museums every month to upgrade the art by painting over or touching up the old art? How about if Ford came to your house once a month in the middle of the night just to change things around in you car? One morning you get up to find they moved your turn signals switch to under the seat, the steering wheel into the back seat, & the switch for the headlights has been placed in the trunk.
Then they offer comfort by giving the lame excuse that everybody resists change, & that we'll get used to it if we try. No, I want my steering wheel in the front seat, & I will not go to my trunk to turn on my lights.
If it ain't broke, don't fix it.
