Problem with your Keyboard, use Mouse instead of it.
Osk: This command is real gem for me I have keyboard in which several keys are totally damaged and I don’t want to spend money for a new keyboard, do you know why? I use on screen keyboard for those keys. To get this keyboard open run type “osk” and keyboard will be open on your screen and you can type using mouse.

Hdwwiz.cpl: It may happen with you also that connecting new hardware does not indicate anything the wizard didn’t come up ask for installation and you wonder what is wrong with the hardware then you have to force the issue open run type “hdwwiz.cpl” the hardware wizard will come and check whether the device is detected or not if detected then it will definitely ask for drivers or it will install itself and if not detected then there must be problem with the hardware or you can manually select the device path if the device is already installed you can check there whether it is working properly or not .

Sysdm.cpl: To open system properties open run type “sysdm.cpl”.

Problem with your Mouse, use Keyboard instead of it.
Type Access.cpl under run command or Go to Control Panel, Open Accessibility Options. A dialog box will appear on screen. Go to “Mouse Tab”. Check Use Mouse Keys. Click on settings, another dialog box appears. You can check if you want to use the shortcut for mouse (left ALT + left SHIFT + NUMS LOCK keys). Define the pointer speed to MAX, would be better, I like it because the default speed is too slow. Also check the option Hold on CTRL to speed up and SHIFT to slow down. You can also select in the option whether to use your keyboard as a mouse when NUMS LOCK key is ON or OFF, OFF would be a better option as you can have lot more things done with NUMS LOCK key is ON. And select OK.

Dfrg.msc: Need disk defragmenter quickly open run type “dfrg.msc”.

Write: To open classic editor open run type “write” wordpad will open.
