Q231327
The information in this article applies to:
- Microsoft Windows 95
- Microsoft Windows 95 OEM Service Release, versions 1.0, 2.0, 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:
File Date Time Size Version ---------------------------------------------------------- Asycfilt.dll 3/08/99 12:02p 147,728 2.40.4275.1 Cfgmgr32.dll 2/19/99 10:55a 22,528 4.10.1422 Comctl32.dll 2/19/99 10:55a 450,832 4.72.3612.1702 Command.osr 2/19/99 10:55a 93,974 NA Command.w95 2/19/99 10:55a 93,034 NA Dialer.exe 2/19/99 10:55a 68,992 4.10.2000 Mfc40.dll 2/19/99 10:55a 933,888 4.1.6140 Msvcrt40.dll 2/19/99 10:55a 326,656 4.22.0000 Oleaut32.dll 3/08/99 12:02p 598,288 2.40.4275 Olepro32.dll 3/08/99 12:02p 164,112 5.0.4275 Regtlib.exe 3/08/99 12:02p 40,960 6.00.8191 Stdole2.tlb 3/08/99 12:02p 17,920 2.40.4275 Setupapi.dll 2/19/99 10:55a 342,288 4.00 Shell32.dll 2/19/99 10:55a 817,664 4.00.955 Timedate.cpl 2/19/99 10:55a 48,640 4.00.951 Vdhcp.386 2/19/99 10:55a 28,053 4.00.956 Winfile.exe 2/19/99 10:55a 155,456 4.00.951 Xcopy.osr 2/19/99 10:55a 3,878 NA Xcopy.w95 2/19/99 10:55a 3,878 NA Xcopy32.osr 2/19/99 10:55a 41,472 4.00.1112 Xcopy32.w95 2/19/99 10:55a 40,960 4.00.951 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
A previous version of the Windows 95 Year 2000 Update (named Win95y2k.exe), only updates the Winfile.exe and Command.com files and adds "Windows 95 Year 2000 Update" to the Add/Remove Programs tool in Control Panel. The latest version of this software update (W95y2k.exe) removes this item from the Add/Remove Programs tool.
A more comprehensive Year 2000 Update (named W95y2k.exe) has since been released (for additional details and download information, see Q225050 as noted in the "References" section below). In addition to this, a follow-up named Windows 95 Year 2000 Corporate Update (Corpupd.exe) has also been made available (for additional details and download information, see Q229862 as noted in the "References" section below).
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 Windows 95 Year 2000 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 should 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 and Q229862, as noted in the "References" section below, contain additional information about these Windows 95 year 2000 updates and the registry.
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. For more information about how Microsoft products are affected by year 2000 (Y2K) issues, please see the following Microsoft World Wide Web site:
