windows 8 crash - apisetschem.dll error c0000221
Posted on 2013-07-01
The machine begins to logon and then stops reporting an error in c:\windows\system\ApiSetSchema.dll error code c0000221.
It then later reports interactive logon failure with an ok command button which can't be clicked either by the mouse or by the enter key.
I don't have any recovery media from the owner of the computer.
How can this be corrected?
