If the Office 2010 ( Excel , Word , Powerpoint etc. ) has some issues on the PC and becomes unresponsive , then running it in a safe mode is a better option .
To run the Office 2010 softwares in a safe mode , follow the below steps . For example , i am using Excel here .
1. Hold the CTRL key and Click the Excel / open the excel document .
2. This will display a popup confirmation box “Excel has detected that you are holding down the CTRL key. Do you want to start Excel in safe mode?”
Click Yes .
3. The Excel should now be opened in safe mode .
