Upgraded my windows 10 to 11 and now my wifi not working.

Wifi not working after upgrading from Windows 7


I have just upgraded to windows 10 from Windows 7. Since doing this my wifi is no longer working. Wifi is turned on but no networks are showing. Unfortunately I only have my mobile as a hot spot to use for Internet so I can not connect an ether net cable to check if it works that way.
I had a vpn installed on my windows 7 system and read that this may be to blame. I reverted back to win 7 and uninstalled it but when I reupgraded to 10 I still have the same issue. I found the following instructions for a fix.. Fortunately – there is a solution.
"Step 1 – First things first, Right-Click the newly-reinstated Start Menu and select Command Prompt (Admin) from the drop-down menu.
Step 2 – Type out the following command, then hit the Enter key
reg delete HKCRCLSID{988248f3-a1ad-49bf-9170-676cbbc36ba3} /va /f
Step 3 – Enter the below command into the Command Prompt and then triumphantly hit the Enter key
netcfg -v -u dni_dne
Step 4 – Restart the PC and then double-check your wifi settings. You should now see a revived list of all of the available networks within range."
However when I try step 1 it says "error: invalid key name. Type "reg delete /?" For usage."
Any help is greatly appreciated as I will have to revert back again if I can't get it working.

 

Upgrading to windows 11

I have a few questions about windows 11...

1. How many GB it is? when my pc suggested the upgrade yesterday, it said it's about 4GB just want to be sure.
   
2. I'm using a windows 10 pro so if I upgrade, will it upgrade to a windows 11 pro?
   

 

Upgrade to Windows 11

I want to upgrade my OS from Windows 10 to Windows 11. I have run the compatibility software and got the message that says my Windows 10 software is not compatible with upgrading to Windows 11. I'm looking for a point & click application that will make my Windows 10 OS upgradable to Windows 11 or a file that will provide step-by-step instructions on how to accomplish the upgrade to Windows 11. I expect a list of files/applications that will not run in Windows 11 because my PC is not capable of running the new applications w/o hardware upgrades.
