What is the easiest way to determine what critical updates and patches
have been installed on windows 95 and windows 98 operating systems?

Hi skip9801,

Good day and thanks for your question.

Although the article says Windows 98, you can use the same method for
Windows 95 as well.

If you have any further clarifications, please don't hesitate to ask,

Thank you for using this service and have a nice day.
