As of 3/31/2012, there are still crashes from HotSpot Shield. Just mentioning because if you haven't uninstalled it yet, it will continue bsoding the machine. If you did remove it, everything is well since it hasn't crashed since 3/31.
You can use CCleaner to delete the minidumps if you wish. It's the "Memory Dump" option.
As for switching account to local, try a different user name.
ok GMan here is how I fixed it, I went to control panel and then there in user account section created deleting a new account and set that as admin account then then deleted the other one with hotmail. and kept files
So it is solved to some extend.
