I just bought a new laptop (Lenovo T410s), and I notice that the Windows key and ALT-TAB don't function. I imagine some kind of function-lock or setting is causing this, but I haven't been able to figure out how to disable it. How do I regain usage of ALT-TAB and Windows key?
It's apparently a known issue on that model Lenovo.
It sounds like a BIOS setting, but I can't find directions on resetting it. Does it show up in your documentation?
Try installing MS Power Tool for Alt-Tab
Try installing this 3rd party software Alt-Tab Thingy
Go to Start => Run and type in regedit
Navigate to: HKEY_CURRENT_USER\Control Panel\Desktop
Look in the right-hand pane for the String 'CoolSwitch' If it has a Value of 0, right-click on 'CoolSwitch' , click 'Modify' and change the Value to 1
OK and exit.
