I have turned on my computer today and a window has appeared titled : 16 Bit Windows Subsystem The message within this window states,"C:\WINDOWS|SYSTEM32|AUTOEXEC.NT. The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose close to terminate the application." Can anyone please tell me how I stop this message from appearing on my desk top every time I start my computer? I am still quite naive with my computer, so I would appreciate someone being gentle with me and giving me simple and easy to follow instructions.I restored my computer to an earlier date that this was not happening but it has made no difference. Thank you to anyone who can help me. Kaye4311.
