I've managed to get into the mouse properties in control panel via the keyboard, but I got as far as getting the message 'aero_nwse.cur' is corrupt or missing. I have copied this into the cursors folder in windows from another laptop, but there's still no cursor. Just done a system restore and that didn't work, tried attaching a mouse and rebooting but no good either.
Any ideas?
It was only a suggestion (guess) that might get your cursor back though :)
t would probably also be worth trying a "sfc /scannow" from the command prompt to see if that throws anything up (rarely works TBH, but if it does all well and good)
other than that, a system restore might work (although I'd always prefer to fix the problem rather than restoring to an earlier date)
Just to let you know how I solved it in case it happens to anyone else - I deleted the driver and it updated and fixed itself without me even having to reinstall the driver. Obviously you have to do all this with keyboard only, but there are ways.
