I have a Windows 7 machine with IE9, and at every system reboot, IE is set as the default program to open pdf files.
If I open the file associations tool and set Acrobat Reader or another program as default pdf viewer, it works for a while and then at the next startup IE is set as default program for pdf files again.
How can I prevent this?
Thanks,
Paolo
