Error message at startup and shutdown

Hi ,

I am part of 2 messages that appear when the PC starts. This message appears when I'm on my home screen:c / Windows / System32/Autoexec: system. The file is not suitable for running MSDOS applications or Windows = do I delete this file C?

At the time of shutting down the machine, I have a message that appears (and prevents the PC shutting alone, I have valid OK to this message) = The instruction at "0 * 00b16500 "Referenced memory at" 0.0000 ". The memory can be read.

If anyone could enlighten me on how to eliminate these errors.

Thank you in advance for all.

For those who have the problem, it is not enough to go autoexec.nt copy in the repair of windows to paste in the windows system32 folder.

This will be OK but the file will be deleted when you stop and windows will restart at boot next.

It seems ally in the properties of this file and put it in system32 to save the attributes read-only and hidden prevents the removal.

I think what you are saying is correct !!!
