Hi, Windows 7 user here.
Why do you have two USB mice connected at the same time? That's deeply unusual.

I'd recommend disconnecting one of them and doing the full suite of Win7 patches and ESR updates (use the workaround to install those). Once everything is updated you may have less issues going forward.

Also I don't know what you're installing that forces Windows to try installing a PS/2 mouse driver however I guess that Windows is freaking out about you using two USB mice (again deeply unusual and uncommon) so it wants to free up some resources on USB or something during install. Just a guess though.

TLDR: Don't use two mice at the same time that's weird or you're doing some 'interesting' workarounds and those can get ya in more weird loops going forward.

Some people use a different mouse for work than they use for games.

Having multiple mice plugged in is fine, it has been common since before USB became ubiquitous. Some games can use multiple mice.

Some keyboards report part of themselves as mice and vice versa. A mouse could report its self as two mice.

However a ghost PS/2 mouse is strange.

Try uninstalling or disabling the device. Use Scan for hardware changes. Clean the PS/2 ports.

its normal to have multiple usb mice seen by windows
many 2.4ghz wireless dingles for keyboards are seen as keyboard + mouse

is there a ps2 keyboard or mouse plugged in?

in device manager, view by connection and see what its attached to

also update bios and chipset drivers

the reason i have 2 USB mice is because i am not the only one using that pc. when guests arrive, they sit in the other sofa and use their own mouse. they do not want to sit with me for some reason. i have tried to uninstall it multiple times but, it just reinstalls itself. its status is that it can not start. i can not update windows because of a software problem.

Maybe a bios problem, sure you can google further if that isn't the solution.

the stuff on that forum does not apply to my problem. uninstalling the ps/2 mouse does not affect anything and all devices connected still work. that pc does not even have a ps/2 connector.

Troubleshooting requires you to try things even if the exact criteria isn't the same. Dismissing things without trying them because you don't think it's relevant isn't going to solve your problem.

i tried it, before i read the post. i had already tried the solution.

if it doesn't make any problems then just leave it be, what's the point trying to fix it.

andreasaspenberg575 Jun 1 @ 10:19am

i am not sure about that. i do want to fix it however.

or is it a ps2 mouse with usb adapter?

check device manager, and sort by connections and see how its connected
