I am having a Windows XP system. I am using Office 2003 on that. It is a quiet old system with decent performance. I will not stay it was extremely fast. But enough to do my work. From last few days I found that it is working extremely slow. I am not able to open or browse my files. When I double click on Excel it takes around 3 to 5 minutes to open the file. It is just a waste of time. I need some help to improve this. I had just installed updated recently that's all.
