Are you using Office 2013? Office 2013 component such Word, Excel or Power Point have start screen as preview what you have done last time and show any template that you can use for your job. Every time you open application, it will open start screen by default.
For any purpose it could be useful but for someone it could be annoying too. Actually you can bypass it as me which I don’t like too many click to open blank document so if I bypass it, Word will open blank document automatically.
How to bypass it? Just easy, I will give example in Word. Open Word main Editor after you see that start screen. Next just click File and try to find Option and click it! Next in General tab of the Option at bottom you will see “Show the Start screen when this application start” and uncheck it then click OK.
To check if it works just close your Word and then open it again and surely Word will open main Word editor with blank template.You can do that way for any Office 2013 suit and if you want to revert to launch start screen just remember to check again the option. I hope this tips will make you comfortable with your computer.
