When i'm trying to install any software its not responding and when i go to task manager its showing that is suspended (which i tried to install).please help...
I've run into the same problem. Do you mean disabling the metro UI by changing the system registy? And then try and install - or do you mean something else?
Yeah I meant just going to the desktop and installing it.
If that doesn't work, you can Always try turning Metro UI off for the installation.
