Assuming a Windows Update is required to fix this, this could take weeks, months? So what to do between now and then? As a business we receive lots of faxes, last look we were at about 1600 faxes this year.
I use a program called Verypdf that automatically converts incoming fax tif files to pdfs. You need to read the verypdf setup documentation, but if I can set it up, I am sure IT people can do it easily. I use a program called AlwaysUp to run VeryPDF as a Windows Service versus a program, that is what works for me.
Verypdf is an old program, but right now with this Windows Fax and Scan issue we are experiencing, I have a work around to manipulate all my faxes as pdfs without using Print to PDF from Windows Fax and Scan. Finally, as the faxes are saved by VeryPDF as PDFs, I can print the faxes out as normal, as the PDFs are not associated with Windows Fax and Scan.
Not an answer to the issue, but a very workable bandaid that may be worth looking at. I will use my bandaid workaround until this gets fixed. Uninstalling updates, not sure I want to do that.
But if someone has a fix, I would love to hear about it!
