And all my e-mail accounts disappeard from Thunderbird. Some Mail icon has appeared in my taskbar that I don't want or need. Office in the Start menu linking to cloud Office that I don't want or need. Stop telling me what I need. I will decide. And I can't uninstall them so does that mean they will sit in memory slowing my computer down? Edge iis consuming memory, I don't want it, and uninstall is greyed out. Great. Not all computer users need their hand holing. Allow us tech savvy ones to personalise our experience. We might even like you if you do but coming in heavy telling us what to do gains you no friends.

I had subscribed to another thread/feed here on the community forum regarding issues with updates.  That thread was closed not too long ago, as though Microsoft considered the issue "settled", or just did not want the thread/feed to continue.  Much like this feed, that one had plenty of not-nice-things to say about these updates, and there were plenty of users having massive amounts of problems with their PC's/devices afterwards.  I see that whomever is bothering to read any of them (or are they just Bots?), is doing the same thing as in the other group.  That is, seemingly, and randomly posting a list of links to click on and follow, in response to their "oh gee, we screwed up yet again on updates".  It would be nice if someone who knew what the in they were doing-would actually give real-world answers to the messes they cause.  But, as many have indicated, I do not think anyone at Microsoft even reads these posts.  Does anyone know of a Microsoft/Windows 10 alternative, because this is my last one.  I have "paused" updates, wrote the date down, and like last time ( few weeks ago), made sure to extend the "pause" (which I was "allowed" to do that time) for as long as I could.  I do not want to buy another Windows 10 when they either break this one for good, or it wears out.  Whichever comes first.

I would be happier if everything rolled back to XP... Lol At least with XP, you weren't forced an update, and you could basically wait to update your computer AFTER Microsoft pulls out all of the bugs they left in it before they rolled it out!

.

This is pretty sad. 

Now, I notice #KB4551762 won't even let me uninstall it. I guess it's just time to switch to Linux.

I can't Install KB4549951, I get Error 0x80073701, I've tried running System File Checker and other suggested methods to fix it that I've found but nothing seems to work, I really don't want to do a fresh install, Hopefully this can be fixed soon

I noticed that after installing the KB4549951 update, I get BSODs with the error "KERNEL MODE HEAP CORRUPTION" whenever I try to do something seemingly CPU-heavy (watching livestreams/conferences, even trying to look at the Event Viewer). I did some experimenting and noticed that the update was seemingly the cause of the BSOD - everything else seems to be fine.

Attached is a zip file with five minidumps. I would like to highlight the ones with the "041920" prefix as those are the most recent ones where the error occurred - I'm not so sure with the other ones. https://1drv.ms/u/s!AjlCoewt-1D7uHESfvzQRMNlZCZd?e=l5fbHh

Tried to find the place to start a thread in Windows section... failed... very simple website Microsoft has here...

Anyways, I've been thinking... Windows 3... it was such an improvement from DOS, I loved it. Then Windows 95 came around, full of bugs, crashed every 5 minutes, made me learn how to save my document every 10 seconds, but it was an improvement from windows 3. Then we had Windows 98, NT, 2000, XP... okay, windows Vista (a hiccup) and then Windows 7... all improvements. Then somebody was hit by a horse, you know, standing behind it, doing something to the horse they should not do, the horse kicks... and Voila... Windows 8 comes around, then Windows 10... While everything was an improvement, I don't think everything in Windows 10 can be called an improvement, especially where you think about going back about 40 years, right where Windows 3 was... but I could still switch between WINDOWS!!! Now I can't any more... Try opening Settings, a window, right? Okay, now I'll try to right click on the desktop and choose Personalize or display settings, change some stuff around and close out. Ooops, where is my Settings window that I opened previously?!?

So everything Microsoft is working on nowadays is backwards. I think the future Windows 10 will look exactly like DOS, and you'll have to type 'nc' in the prompt to start something like Norton Commander to get around your computer, only this time it will require a ton more resources than back then.

Oh, a Snipping tool is moving... Now I'll have to press several keys involving my big toe on the right foot to press one of them to take a screenshot... Really, Microsoft?!? I don't want to learn yet another tool, which most likely is going to be over-complicated and a step back anyway. Why not just improving something we already have?

I'm done with my rant... Microsoft is improving nothing, just complicating everything.

Thanks for reading.

Val.

Almost anything you want to do on your computer can be done without using keys at all. Including screenshots. Say "Hey Cortana, LAUCH SNIP" and you will see this.

Image Then just tell her which tool you want. But, for a screenshot your windows key +prnt sc will continue to work just as well as it always has. How so we open settings? "Hey, Cortana, Open Settings" usually works

If these simple tools aren't working for you you may need to run a repair program or even reinstall Windows altogether.
