Let me share I cheated. I never installed a mouse driver. I let windows figure it out. My thought and idea is a boot to SAFE MODE (see google) and then in SAFE MODE find the DEVICE manager to remove all mice there. Reboot and let Windows rediscover the mouse.
I lose usage of my mouse when I reboot my Windows XP Home Edition SP3 after the following actions:
1. registry clean up with CCleaner
2. disabling of one or more unncessary service(s) from within services.msc
I also noticed that when I reboot one more time the mouse issue goes away, but it reappears at the next reboot and so on (it appears every two reboots...).
Each time I have been able to reverse changes OK by coming back to the System Restore point I had created before the changes.
Any idea as to what could be the issue and next troubleshooting steps?
