It seems that the only program that can reliably export or convert .shw presentations would be the program that was used for making them in first place - Corel Presentations. The program also supports export to PowerPoint formats (.ppt among others), so it seems that it is the obvious and perhaps also only choice for shw to ppt conversion.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
