Question:
I installed NT 4.0 over 95, and now what’s thebest way to uninstall only NT? Leaving 95 asit is.

Answer:
Yes, you can boot your computer with a Windows 95 bootable floppy disk and use the “sys C:” command to return to your Win95 configuration. You will also need to remove any of the following files that exist in your root directory: pagefile.sys, boot.ini, ntldr, ntdetect.com, and ntbootdd.sys (some will be hidden and/or system files, and you will either need to use a utility that will delete these kinds of files, or first remove those attributes).
