It's a long while since any reply to this thread has come about!
"How to reset windows mouse settings" but the info here in this thread is clever
and not too old... so I joined and this is my first post.
brandonengell is asking the same thing I needed to know for an old Win98se machine, so
here is the answer for this OS = 98se and it worked pefectly after I rebooted.
Run regedit and use this fairly self explanatory way of setting your mouse to default
for Windows 98 ,not exactly default but this may be closer to what you are looking for?
There is likely just as simple a way for 2K or XP but I opted to join and post here instead
of search this out but I will find out for my I7 machine that sits in parts in boxes until
time allows assembly.
I am an avid gamer in mind with no time to be avid as to play like I used to.
Thanks to this URL and it's writer.
This reg file contains the general mouse settings.
