you may have entered the command wrong there must be a space after dir and after the s
dir /s win.com
also try:
cd c:\windows
win
It sounds like win.com is there when you entered "win" or you would have gotten an error message right there.
I don't know what's happening with the msgsvr error; they are often associated with other running programs causing conflicts.
Have you tried choosing Safe Mode from the Boot Menu?
Here is a list of documented msgsvr32 errors, see if yours is similar to any listed. If there is a details tab on the message, click
that for more info.

If you can get to the Windows directory in DOS, it might help to delete your passwords, which can be a source of msgsvr errors.
Try this command from c:\windows>
del *.pwl
by the way, sometimes Windows gets installed into a "new" directory whether you specify it or not. From the c:> prompt just enter:
dir /p
does Windows show up in the directory listing? Are there more than one
also try:
dir windows /p
the /p switch will pause the screen, hit a key to continue. You may see win.com in there
