# Windows – Microsoft Office 2010 Excel will not open two xls

microsoft excelmicrosoft-excel-2010microsoft-officewindows 7xls

I am using Windows 7 and Windows 8 and I see the following behavior with Microsoft Office 2010.

Create two Excel files, say a.xls and b.xls

Open a.xls by double clicking it.

After the file is opened in Office 2010 Excel, modify this file and do not save.

Try opening b.xls. by double clicking on it.

b.xls never opens.


This behavior only happens on Windows for excel files on 2010.

It works fine with any other type of files (.doc, .docx, .ppt etc). It also works fine on Office 2011 and Office 2013.

Is there a workaround for this? Any patch etc?

Highly appreciate any insights.

Thanks!
