The most common mistake in the computer can only be to a blocked program that is not responding or will not open.
Usually to solve a similar problem just restart the computer and the program continues to run but for a quick solution you can simply close the process corresponding to this program and you have solved.
To close the hung process in task manager you have to go (just hold down Ctrl-Shift-Esc) and select the processes tab and close using the button on the bottom right, the process stopped.
The operation itself is not complex, but be careful to always check the flag \"Show processes from all users\" at the bottom left and the name of the process that corresponds to your program stopped, in fact, many programs have processes with names several such as:
- Word -> winword.exe
- Outlook Express -> msimn.exe
- Adobe Reader -> AcroRd32.exe
- Interner Explorer -> iexplore.exe (be careful not to close explorer.exe)
- Open Office Write, Calc, etc. -> soffice.bin and soffice.exe
You can find different processes with the same name, this means that you have tried several times to open the program and then close them as well, for a better identification can order by clicking on the column \"Image Name\".
