SUMMARY

This article discusses how to determine which Y2K patch is installed on a computer. Currently, there is no tool, as such, to determine which patch or patches are installed.

MORE INFORMATION

To differentiate between the patches:

Run the executable file with the /x argument (for example, type y2kfixi.exe /x). This allows for the extraction of the contents of the hotfix file to a specified location.

After the executable file is extracted, observe the following information to determine which hotfix you have:
