i've uninstalled, installed, updated, blah blah blah. HP My Display screwed it all up

Really sucks because it seems as though there's nothing to do. HP made a crappy product, oh well. They'll just ditch support.

I don't think 10 is perfect, but it's way better than 8 and is improving as time goes by. 

Yea hp is a shit company imo

A few weeks ago, bestbuy had a sale on hp laptops with i5s in them. So my friend got one and the functions keys didnt work cause there were no drivers for them. This is a brand new laptop too.

If it didnt cost 400 cad for i5 and 8gb of ram, would have told her to return it but since the deal was still great, I just showed her how to do it through windows 10. Otherwise would have told her to go with Asus

Windows 10 is the reason to move to Linux for me and even some companies I know of. I am a Windows fanboy and loved 95, 98, ME, NT, 2000 and 7 becauseit made my life so much easier and more productive. But with 8 and especially 10, something went wrong. Life got harder, much harder because the interface is slow, less productive, inconvenient and outright unusable.

As Microsoft doesn't seem to care it is time to say goodbye. For me this is not easy because I love my Windows 7 and I never liked Linux that much, because you have to edit files and change settings in command line so often. But I could never have imagined that a Microsoft OS could be worse.

I actually never thought about using HDMI in for consoles. Why not just use the HDMI ports on your monitor?

Windows 10 was terribltbunstable on my PC till I disabled all background apps that were enabled by default, these would eat into my RAM and CPU usage and cause programs to crash (and sometimes the whole system, memory protection my ass). My desktop would at random be thrown in dissaray and don't get me started on their update policy.

I've had no problems with Win10 on any of the systems I've run it on, which are very numerous. I always remove the terrible cortana search bar, unhide file extensions, and install classic shell though, along with fresh non-bloatware fresh installations.

Some older software that have certain dependencies can be unsupported (rare devices, things that use old versions of .net like old salesforce plugins, quickbooks pre-2013, etc).

In your case, it sounds like a fresh install of the original OS version would be the best way to go, with the bare minimum in drivers. That kind of install generally has the best results anyway, OEMs tend to put a lot of spam/crapware on there. Dell and HP are notorious along with Toshiba about this kind of thing. Dell Support Center, Dell Cloud Backup, Dell Documentation, Dell diddly-do-blop, Dell dingo-de-bongo, etc, etc, etc, etc. It's crap. I have a Dell i5 laptop that I replaced the stock hdd with a new SSD, upgraded to 16GB ram, and did a totally fresh install of W10 on, absolutely zero Dell software, and it runs absolutely flawlessly. This is the same story with a huge number of PCs and windows versions over the years, OEMs simply can't be trusted not to force a bunch of useless garbage into the factory loadsets, and it's absolutely maddening.

is your HDMI port running of amd or nvidia driver? I now my hdmi stopped working on Windows 10 till i got the latest driver DIRECT from manufacture not the shitty thing windows put on. That solved my issue.

Of course it's ridiculous. It's Windows, what do you expect? Windows has been ridiculous for more than 20 years now! It's a feature by now!

I had a laptop that was running like garbage on W7. I updated it to W10 and it is fast and responsive. My current laptop was a W8 laptop that had a HDMI that wouldn't work. I updated it to W10 and now it does! Its like opposite world from your problems. W10 helped my stuff.
