Hello Panos,
It sounds like you have inadvertently changed the default Windows action
when double-clicking on a *.PPT file from Windows Explorer from "Open" to
"Show"
You can change this as follows
1) Open Windows Explorer
2) Tools -> Folder Options
3) Switch to the "File Types" tab
4) In the list select "PPT Microsoft PowerPoint Presentation"
5) Click the "Advanced" button
6) Select "Open" from the list of Actions
7) Click the "Set Default" button
8) Click OK
9) Click Close
Now try to open a *.PPT from from Windows Explorer.
