My Windows Explorer (note: NOT Internet Explorer) has recently started having problems. I can browse through files perfectly fine, but if an external application tries to open up a "Save as…" or "Open…" menu, then nothing happens. Because of this, I can no longer attach files to my emails or decrypt my FreeOTFE volumes. How can this be fixed?
(Note: After running sfc /scannow, it told me that my shell32.dll was corrupted. This is because I have manually edited it. However, I am unable to change it back. Could this dll be the source of the problem? If so, how can I restore it?)
