Windows 95®  Operating System Updates

Back to Windows 95 Help

Is your Windows 95 Operating System up to date? If the answer is "No" or "I dunno", there are some links below that can be of help in finding the answer or making it yes. These files are for Windows 95 version 4.00.95, also referred to as the "retail" version by Microsoft. When you complete the upgrade, it will be version 4.00.95a. To find which version of Windows 95 you have, Right-click "My Computer" and choose properties You should then see something similar to the picture below. 

The reason I created this page in particular, is the tendency of Windows 95 to "crash" and need to be reinstalled from the CD or diskettes. When that happens, if you don't have all these files locally on your computer or on a CD, then you have to search all over Microsoft to find them, and they are forever being moved, there as they continue to update their systems. This is more convenient for people locally.
The simple way to tell what version of Windows you have:  
  • When did you buy your computer?
  • When was Windows 95 installed on it?
  • What version is listed, as at the left?
  • If the answer to either of the first 2 is pre-1997, chances are you have the same version as shown.   

    A good strategy to start the upgrade is to get service pack 1, the Password List  and the Update Information Tool, install them in that order and run the Update Information Tool from the Accessories/System Tools Option on the Start Menu to get aid in deciding what you have or need to get afterward. 

    If the answer to the third "Q" is 4.00.950b or 4.00.950B or 4.00.950c or 4.00.950C, then most of the files on this page don't apply to you. Some of these files apply to nearly everyone who uses the Windows Operating System ®. Anyone trying to identify an OSR version of Windows as to whether it is version 1.0, 2.0, 2.1 or 2.5, ect.  should check with Microsoft directly. 

    note: This page is currently being updated, old unnecessary updates are being removed and new files added. ETA on completion is the week of March 6, 1998

    The Out-of-Band Issue  as it affects Windows 3.11      The only known fix is to exit Windows, to the DOS prompt, and enter the \WINDOWS\SYSTEM  directory. Rename the file vnbt.386 to something like vnbt.old. Reboot and restart Windows. You will receive an error  message from Windows, but this will not harm your system. This fix will, however, disable file sharing in Windows 3.11, so you can rename the file to its original name and reboot to use file sharing features. Microsoft has not announced an official fix,  yet. If they do, I will post it on this page.
