Shortcut keys to shortcuts abruptly stopped working
Basic: OS = Windows 7 Pro; computer is a Toshiba Satellite L70-A
Yesterday, I had numerous working shortcuts to shortcuts (e.g. Ctrl+Alt+G to start GoogleEarth). This morning, after seeing an error message related to APO3GUI, and finding it related to DTS sound, I un-checked the DTS Studio Sound in the startup tab of System Configuration, and restarted the computer. I had not, prior to that, attempted to use any shortcut keys. However, after the restart, I found my shortcut keys had all "died." Subsequently, in my attempts to get them working again, I have done the following, in order, with restarts between each one, to no avail:
1. Re-enabled DTS Studio Sound in System Configuration.
2. Checked Windows updates and saw two Windows Security updates, KB 3212646 and KB3207752, showed as having been installed today (1/12). Uninstalled both from Windows Update.
3. Ran System File Checker -- no issues found.
4. Un-assigned and reassigned a shortcut combination.
5. Started in SAFE mode.
6. Started from "Last Known Good Configuration".
7. Did System Restore back two days.
I'm out of ideas!
P.S. -- wasn't sure which forum this would be better in, so here by default.
