We had a powerpoint emailed out to everyone in our building. &nbsp;Some of the machines are Win 7 and most are XP. &nbsp;Two of the windows 7 machines had a serious problem right after running the powerpoint. &nbsp;They associated EVERY executable with one program: Picture Viewer. &nbsp;Uninstalling MS Office and rebooting fixed one of the machines but not the other. &nbsp;No other machines have shown any symptoms and almost everyone ran the same powerpoint. &nbsp;No viruses have been found. &nbsp;<br />
<br />
So, why did this happen, why Windows 7, and how can I fix this second machine?

Windows 7 machines associating ALL exe's to one program, why?

Windows 7 is an operating system from Microsoft. Features include multi-touch support, a redesigned Windows Shell with a new taskbar, referred to as the Superbar, a home networking system called HomeGroup, and performance improvements.
