Windows 10: Corrupted C: drive?

While Windows 10 HOME edition is starting I get "Preparing Windows", which I had never received before.

Once I log in I get:
"We can't sign in to your account.
This problem can often be fixed by signing out of your account and then signing back in.
If you don't sign out now, any files you create or changes you make will be lost."

Which account might the message refer to?

:)

Are you able to follow them?

Corrupted file RAR

If the archive has been created using WinRAR, why don't you try WinRAR itself? It has a built-in repair feature for repairing corrupted archive (ZIP as well as RAR). Follow the steps given below:

• Open WinRAR application in your system.
• Now click on File tab > Open or simply press Ctrl+O.
• A small window "Find Archive" will pop up. Locate the corrupt RAR archive from your system directory and select it.
• Now click Open button.
• Click Tools tab > Repair archive or simply press Alt+R.
• Again a small window "Repairing File name.rar" will pop up.
• Now click Browse to select a location to save the repaired archive.
• Check the box "Treat the corrupt archive as RAR" and click OK.
• WinRAR will start repairing of corrupt RAR archive. Once it gets completed click Close.

I hope the above steps will help you repair the corrupted RAR archive.

Thanks.
