Under system performance tab, I see that something called compatibility mode is being used. The message informs me that this mode is because there is a device driver in the config.sys or autoexec.bat that is bad, but Windows was caring enough to make things work anyway.
Both config.sys and autoexec.bat are empty, I'm using defaults. How do troubleshoot this.
It is noteworthy that I deleted a file by accident called system.1st from root. Any relationship?
