Hello, I’m Virginia, I have 20 years of expertise in fixing my own & friends’ PC problems.
Sorry to hear you’re experiencing problems. Are you running Home, Home SL or Pro? Did the pc come with Windows 11 or was this an upgrade from Windows 10?
Please note we’re just fellow users like yourself & not Microsoft.
Did the pc come with Windows 10 or 11 pre-installed or did you purchase a key? Please run this to see what is currently installed & post the screenshot:
Right click on start & choose powershell with admin & enter: slmgr.vbs /dlv
This will show a popup showing whether your license is OEM, Retail, or Volume amongst other information.
Have you tried using the default key to activate? Depending on the answers to the above questions I will provide the specific key.
When you contact support you will have to go through automated support, if you type speak with an advisor you should be put through.
