Microsoft Excel 2007 Opens Very Slowly
Extended title: Microsoft Office 2007 or Excel 2007 opens very slowly when I click on an icon to open a document.
A client was having extreme delays when opening Excel 2007 documents on all of their computers. My search led me to a two part solution. The second part came from this blog.
First, check the XLStart menu under C:\Program Files\Microsoft Office\Office12\XLSTART. We had PDFMaker.xla which was causing some issues.
Next try the following. This made the largest performance improvement.
1) Open Windows Explorer and go to Tools -> Options and then select the “File Types” tab
2) Click Advanced
3) Click open and then select edit
4) Now click open and then select edit.
5) Add "%1" (with quotation marks) to end of the “Application use to perform action:” and then click OK.
6) Mine looks like the image below with the highlighted text being the text I added
