windows 10 update, the bane of the existence of anyone who wants to get thing done with a computer. i would still be using 8.1 had my motherboard manufacturer decided not to support earlier versions of windows (last time i buy asus). i was in the middle of an embedded project, with dev boards, jumper wires, modules, arduinos, all strewn about, cats also taking up any remaining space such that there is no room to get anything done.

on about the 50th try trying to flash grbl on an stm32, i get this popup telling me my system needs an update. so i go ahead and do it and use the time to go upstairs to pee and build a wiring harness for a stepper motor. i come down and find that my wifi doesnt work anymore. no problem i have a degree in networking i can fix it. dhcp keeps trying to allocate an address that's outside of my router's subnet, routers working fine other computers dont have any trouble getting internet. ok release and renew. nope. i figure ms screwed up a driver update and needed roll it back. lol,no, sorry dave im afraid i cant let you do that. il have to do it manually.

so i go over to another computer grab the onboard wifi driver from the asus site. there are 3 versions so i download all of them. one of them is a whopping 400+mb, for a ******* network driver. anyway i instal them in series from newest to oldest, removing the old version and rebooting in between. none of them work. in the process i noticed that batch files are opening in notepad++ rather than launching. i fix the file association and i start the whole process over again. no dice. so i just reinstall the most recent version.

so screw that il just use a static ip. set up a reservation on the router, then set the adapter to use it. dns to all ones. gateway to the router's local ip. no internet but at least i can get into the router config without getting up. theres not much i can do there. by now several hours have passed.

windows 10 has this annoying problem with having 2 interfaces. the old skool config windows that haven't changed much since windows 2000, you know the ones i can operate on autopilot because of years of muscle memory. and then they have the hiptsterized interface with much fewer options but hey at least they look pretty. its like giving the inside of your engine compartment a fancy paintjob even though you only open it when there is a problem or for standard maintenance.

thing is if you change a setting in one, the other one keeps the old setting, its sort of like a tug of war, if you dont change it in both places it doesnt stick. idk what did it, i tweaked so much stuff that im not quite sure what setting fixed it. know i turned off firewall and disable my antivirus, and screwed around with every ip/network setting imaginable. but the little yellow blip on the tray icon disappeared, i opened chrome and got google to come up. so i finally got a working static ip, and im still clueless as to why this broke in the first place. anyway i start undoing things i did to try to revert anything that didn't need to be changed, but each time things stopped working. no dhcp, no windows firewall, but it works.

what is it with developers these days? changing old interfaces for what, so you can make the old people look stupid? at least have the decency to get rid of the old one so they dont get confused. rolling out updates more broken than what was already running? and for what? increased security? most people get hacked because of social engineering, or doing something stupid, or pissing off the wrong person by being an *******, not because they didnt install their updates. curse them all.

end of rant

The reason for this is to keep people in "IT" employed, people who can't speak freaking English and are so aggravating that you want to beat your head into a wall. So they have a degree on the wall, no people skills or the ability to understand what the blip you are trying to tell them.

im convinced that ms keeps renaming things so they can sell certification courses for each new version of windows.

and tech support is an utter scam. you give them one of the 100 most stupid common computer issues they can help (so can 2 minutes with a google search bar). but give them a real problem and they are clueless.

so i finally found the correct netsh command to unscrewup windows. intrestingly enough these commands are not on any official documentation from microsoft. dhcp works now and my firewall is working again.

and frankly if i have to learn a bunch of command line stuff id be better off on linux. at least on linux many of those common commands havent changed since the 70s (inheriting unix wealth).

Please post the netsh command utilized and have a mod move this to the workaround subfolder

i tried several from various tutorials, including both the ipconfig and the netsh commands:

ipconfig /release
ipconfig /release6
ipconfig /flushdns

netsh winsock reset
netsh int ipv4 reset
netsh int ipv6 reset

however while this worked once, i couldnt get it to work again after that. so there might be some other commands ive forgotten.

i had problems using it with my vpn, and had to put it back to a static ip address and kill the firewall for it to function. after which i was unable to restore dhcp. this is a good backup method to restore functionality should you not be able to get dhcp to work.

ipconfig /release tells the computer to forget your IP settings, if you are not using DHCP and plan to set everything up manualy that is fine but usualy you would want ipconfig /renew instead which forgets the settings then pulls new settings from DHCP.

if you are on a static IP you should still be able to access the internet, if you cannot and have not tried it I recomend you set DNS manualy, my go-to if I cannot reach the the local networks DNS or if that is not working (and the secondary on most other computers I set up static IP on) is 8.8.8.8, that is a google provided DNS server which seems extremely reliable.

Microsoft Windows 10 has these periodic "creators updates" which each time they release one it breaks something major, last one broke wifi for every laptop and tablet model my company uses, as well as forced us to recreate all user profiles on about 30 desktops, fortunately we managed to block the update after a "mere" 60 machines were infected updated, much easier to fix than if all 1600 or so had been, strangely this started happening after M$ fired all their Windows update software testers, what a suprise fire your software testers having decided they were no longer needed, then suddenly they end up breaking something major with each update, who could have possibly predicted that? evidently M$s management are not that smart.

previous creators updates have broken things like ethernet through docking stations, sound drivers, graphics drivers, drivers for network printing on HP plotters and caused MS Offiice activation to break so we (the 5 persion servicedesk) had to repair Office on about 500 PCs.

Even after all this the head of IT still thinks it is a good idea to push updates instantly they become available because he believes "testing is a waste of time unlikely to discover problems", I would have agreed with in the days that XP or 7, but not with 10, if we deployed the update to one of each of the 15 or so models of PC in use in the company and had someone test the common functionality we would have known what the problems were and blocked the update before breaking important functionality required by hundreds of people

If looking to optimize DNS server for your region suggest DNS benchmark at grc.com
https://www.grc.com/dns/benchmark.htm
There are other similar programs out there now.

As for head of IT pushing updates asap, thats usually company policy.
Doing so lets IT avoid getting fired asap for not updating when some idiot clicks link in email containing 0 day exploit, to listen to a fax message from UPS postal service regarding fedex refund shipment attached urgent reply required asap or CIA will charge and arrest for viagra IRS tax evasion, etc.

After a the spring patch last year that arrived in August that killed speaker sounds I started calling it the "creatures updates".

my computer knowledge (i hold a couple it degrees) of olde tells me that dhcp is a tried, true and very reliable protocol for getting an ip address from somewhere that gets you on the internet. apparently nobody told this to the windows 10 dev team and they managed to screw it up. id love for it all to function the way it did before windows pushed one of its forced updates but that's absurd to expect a modern dev team to actually do their job.

anyway im using cloudflare dns. but dns only works if dhcp does its job, and it can't do that if you don't have a valid ip address. instead of windows giving you an ip that is actually on your router's subnet. instead of picking one at random, and no not the common 192.168.1.* ip that all consumer routers seem to use by default, no something weird that doesn't make sense. it's just horrible design.

when i decided to stop using the rather unreliable dns from my isp, i just went down a list of top dns servers and pinged all of them. cloudflare seemed to have the lowest ping time, but granted it was only like 1ms ms faster than the others. of course the difference is small enough to be a rounding error. i dont think the internet needs sub-millisecond-resolution timestamps any time soon.

Par for the MS course...
I mean, come on. Back in the day I had a triple-boot system. DOS/Win3.1, OS/2 (2.1, I think at the time.) And I threw on Win95. It worked, sure. Then I went to upgrade my modem (to a blazing fast 14.4. Woo!) DOS? Hop in a config file, change a parameter. OS/2? Same thing. Win95? Took an hour because it decided my modem was actually a mouse and would not release it.

They had gotten better with (later-patches) XP and Win7. Now with 10 they're back to hiding and splitting settings up between two different control panels and removing access. If you don't have to *do* anything to it? 10 is fine. If you have to work on it? Erg.

it runs everything i need it to run just fine, its just core features of the os like to not function and i have to rely on a stack of workarounds which might cause other problems down the line.
