Win 95 Update and Download Page

Unlike Win98, Win95 does not update automatically.  So it is your
responsibility to keep up to date.  One necessary tool is QFECHKUP
(http://support.microsoft.com/download/support/mslfiles/QFECHKUP.EXE.)  This
tool lets you check your system files for current versions.

Here is the official Microsoft page for all Win95 Updates,
