Windows 10: Windows 11 Pro product key gone after power outage

Last night there was a power outage in my dorm room while my PC was running. Turning it on today I'm told that "Windows reported that no product key was found on your device. Error code: 0xC004F213" Is there anything I can do to fix this? It's Windows 11 Pro if that helps, thank you

:)

 

Windows 10 product key unusable after power outage

About a year or 2 ago I bought a product key for Windows 10 for a home built PC. It worked just fine but I didn't link it to my Microsoft account. About a week after installing there was a power outage and when power was restored my PC was identified as
a different PC, making the product key invalid, and that product key is now assigned to a PC that I guess no longer exists... For a while I was able to put up with it but now its just driving me nuts with the Activate Windows watermark and the inability to
customize anything. Any ideas?

 

Power Outage

Hi there, I just had a power outage and i'm worried that my windows installation will be damaged. I have an SSD. Should there be any steps I should do now? What should I check?

 

Power outage caused programs to disappear and/or become disfunctional

Hello,

There are few factors that can contribute to the issue you are encountering. Power outages can result in data loss, corruption of folders/files, and programs not functioning.

To assist you further, kindly provide more details by answering the following questions:

• Which browser are you using to check the passwords and favorites section? Provide the list of browsers where you encountered the concern.
• Have you tried using another account to verify if the programs are still missing on your program list?

There is a possibility that the drive index has been corrupted. We highly suggest that you check your hard drive and scan for errors by following these steps:

• Open This PC on File Explorer and locate your hard drive.
• Right-click and choose Properties.
• Under Tools tab, click on Check Now button.

After scanning the hard drive, hidden files and folders, as well as lost data can be restored.

Additionally, we advise running the System File Checker as another way for us to check or scan for data corruptions in Windows system files that can be affected by the power outage. To do so, follow the steps on this article:
