The information in this article applies to:
-
Microsoft Windows 95
-
Microsoft Windows 95 OEM Service Release versions 1, 2, 2.1, 2.5
SUMMARY
The Windows 95 Year 2000 Upgrade is not displayed in the Add/Remove Programs tool after it is installed. It is not displayed because it should not be removed.
To determine whether the upgrade is installed, check for the presence of the Y2kw95.txt file in the Windows folder. You can also check the following files to verify that the files are the correct ones:

Y2kw95.txt 2/19/99 10:55a 23,611 NA
NOTE: Files with an .osr or .w95 extension are specific to the Windows version and are renamed with the appropriate extension as shown below:
Command.com
Xcopy.exe
Xcopy32.exe
IMPORTANT: If other products or updates have been applied, certain files may not be replaced by this update. For example, if you have Microsoft Internet Explorer 4 with the Windows Desktop Update component installed (or you install it when you are prompted by the Year 2000 Update), the Shell32.dll file listed above is not installed with the Windows 95 Year 2000 Update installation. Manually replacing the Internet Explorer 4 version of the Shell32.dll file with the version included in this update can result in "fatal" problems at Windows startup or a blank desktop. Under no circumstances should a file that is not overwritten by the Year 2000 Update be manually updated. Because of this, Microsoft recommends that if you are unsure of the status of the update that you simply reinstall it to verify its integrity. Later versions of any of the above files will not be updated by the Year 2000 Update. This behavior is by design.
MORE INFORMATION
If a previous Windows 95 Update (Win95y2k.exe), which only updates the
Winfile.exe and Command.com files, has been installed, a "Windows 95
Year 2000 Update" item appears in the Add/Remove Programs tool in Control Panel. (See Q182967 as noted in the "References" section below).
A more comprehensive Year 2000 Update (W95y2k.exe) has since been released
(for additional details, see Q225050 as noted in the "References" section below). In addition to this, a follow-up Corporate Update (Corpupd.exe) has also been made available (see Q229862 as noted in the "References" section below), which removes the above-noted item from the Add/Remove Programs tool, as well as attending to other housekeeping issues.
Activation of the "Windows 95 Year 2000 Update" option in the Add/Remove Programs tool results in the computer becoming non-year 2000 compliant. For this reason, Microsoft recommends that you obtain and install the Corporate Update.
To determine which version of the update is installed, check the Add/Remove
Programs tool. If the update is listed, the older patch is installed and may need to be updated. Check for the Y2kw95.txt file in the Windows folder to verify that the newer update is installed.
Note that the Microsoft Year 2000 Product Analyzer tool available on the Microsoft Year 2000 Readiness Disclosure & Resource Center Web site was released before the Windows 95 Year 2000 Upgrade and does not detect the update after it is installed. Checking file versions is the only reliable way to detect that the update is installed.
Microsoft Knowledge Base article Q225050, as noted in the "References" section below, contains additional information about the Windows 95 year 2000 Update and the registry.
Microsoft Knowledge Base article Q229862 as noted in the "References" section below contains additional information about the Windows 95 year 2000 Corporate Update and the registry. Note that the article discusses a QfeCheck tool that can readily verify that updates have been installed on your computer (see Q161020 as noted in the REFERENCES section below).
The W95y2k.exe file is for all versions of Windows 95, and automatically installs the appropriate files for the version of Windows 95 you are using.
