Windows 10: My older model laptop isn’t working at all after it tried to install windows 11?

I was doing schoolwork on my laptop as usual. Then a screen popped up saying my laptop ran into a problem. It then started to try to self fix it I guess? Then it said it couldn’t do automatic repair, didn’t start correctly and to restart the laptop, but when I press restart it just repeats. It’s genuinely not usable at this point. I bought this laptop not long ago and it was working fine except for a little lag but that’s normal for an olderish model up until yesterday. I think it was trying to install windows 11 but failed because it doesn’t have the memory for it or something. Is anyone el

Printer isn´t working after latest update.

After the latest update from Windows, my Canon Pixma ip6600 printer isnt working. In Device Manager it shows up as working properly but when I go to print it isn´t listed as an option in any programs. Troubleshoot suggests it´s a USB 2 printer on a USB
3 port and that that´s the problem but that cant be since it worked fine before the update. I´ve tried to uninstall and plug it back in but that doesn´t work either.

 

Cortana isn´t working

When I hit enter, it did something, but there´s still no Cortana, even after restart. So I tried it again, but now it says that it failed, because it´s already installed and it´s working in PC. So it should work, but Cortana still isn´t here.

 

Razer Kraken V2 - Microsoft Teams (work or school) says "Your speakers aren´t working" & "Your microphone isn´t working"

Since I upgraded to Windows 11 my Razer Kraken V2 can´t be used for calls and meetings in Microsoft Teams (work or school).

While making a test-call there comes a pop-up saying: "Your speakers aren´t working" & "Your microphone isn´t working".

With the newest software installed from the Razer Website (Razer Synapse 3.7.131.11810 & Razer Synapse 2.21) it isn´t working.

When I tried to unistall Razer Synapse and reboot afterwards, it won´t change a thing - the only solution was to unistall razer synaps, uninstall the driver in the device-manager for the headphones and also for the microphone.

No Razer Synapse means no 7.1 sound, nor bass optimization.

I already asked the Razer support about that topic - they said when everything else (beside Microsoft Teams) the problem isn´t on their side?!

A Week ago, everything was working fine under Windows 10, thats the funny thing.

Any guesses what to do, so it will work again with the correct drivers?
