Windows 95 Patches & Updates Guide


Securing Windows 95 is a difficult task. Updates are not longer provided for the core operating system, and for most of the main system components.

It is important to remember if using Windows 95 that it is no longer a supported Operating System. You will find that the software required to provide additional security will not function. As a result we recommend that you look to upgrading your Operating System to a newer one.
If you must use Windows 95, we recommend that you do not directly connect the system to the Internet and minimise any network shares that you setup on the computer. Do not serve any information to the Internet from your system, such as using Personal Web Server to host a web site.

This guide is primarily aimed at Windows 95 RTM users, but applies to all of the following Windows 95 Releases

  • 4.00.950 (RTM)
  • 4.00.950A (Service Pack 1 / OEM SR1)
  • 4.00.950B - 4.00.1111 b (OEM SR2)
  • 4.00.950B - 4.03.1212-1214 (OEM SR2.1)
  • 4.00.950C - 4.03.1214 (OEM SR2.5)

If you can start with a fresh install of Windows 95 we recommend that you do the following:

  1. Perform a fully custom installation
  2. Only select the optional components that YOU need
  3. Do not install Dial-up networking if you do not need dial-up
  4. Do not install LAN components unless you need it
  5. When installing a LAN, make sure not to install unneeded components and protocols.
    NetBEUI and IPX/SPX are installed by default, where as TCP/IP isn't. Usually only TCP/IP is needed

Recommended Installation Procedure

Before installing any operating system it is important to have all of the pieces of information and software that you will need in order to successfully get up and running.
The main information that you will require are:

  1. Product Installation Key
  2. Network information (If Applicable)
  3. Make and Model of your system hardware
  4. System Drivers, (notably Display, Modem and Network)

Drivers will have come with your PC, its hardware or both. It is important to note however that these drivers may not be current versions. Having updated drivers can provide significant performance benefits for your PC. We recommend that you crate a list of all the manufacturers of your system hardware and then check their web sites for current drivers.

NB: If you are installing a Network Interface Card in your PC, ensure that you have its drivers on a floppy disk.

  1. Begin the Windows 95 Setup program
  2. Enter your Name, Company information and product key when prompted
  3. When prompted to chose an installation type select Custom
  4. Go through each of the Installation Options and choose the components that you need, click Details to see more on each category
  5. Allow the hardware scanner to search for all hardware devices
  6. On the Network Installation Screen, if you need a Network Card and it wasn't automatically detected add it using the drivers on the floppy disk.
  7. Ensure that you only install the protocols that you need. Most LAN's require TCP/IP and not NetBEUI or IPX/SPX
  8. On most Networks "Client For Microsoft Networks" is only required "Client for Novell Networks" can be removed
  9. Add and Enable File and Print sharing Only if you need it
  10. Complete the installation, providing additional drivers and information if required
  11. Once on the Windows 95 Desktop, install the rest of your Hardware drivers
  12. Install the Service Packs and SRP's section from the Patches and Updates Guide below
  13. Install Microsoft Internet Explorer 5.5 SP2 and the Desktop Shell Update+*^
  14. Follow through the rest of the Windows 95 Patches & Updates Guide (Below), installing the updates, fixes and add-ons listed
  15. If you use Dial-up networking on your PC, ensure that you install the Dial-up Networking 1.4 Update
  16. If your PC has an Infrared port & you wish to use it to sync your Handheld PC install Infrared Transfer 1.0 & IrDA 2.0 Infrared Drivers
  17. Install your preferred web browser if you wish to use an additional one, ensuring you have the latest version
  18. Visit Windows Update to check for anything additional that you are missing on your system configuration

* Although you may not actively use Microsoft Internet Explorer, installing it updates system components and security. Many other applications that you will need in order to Synchronise with your Handheld PC will require Internet Explorer. It is best to do it now

+ The Desktop Shell Update is not available in Internet Explorer 5. Installing Internet Explorer 4.01 SP2 will install the Shell update, then install IE 5.5 SP2 afterwards. HPC Factor offers a IE 5.5 SP2 with Active Desktop as a download here

^ Internet Explorer 4.01 SP2 and Internet Explorer 5.5 SP2 are no longer available for download from Microsoft.com
