Errors in your registry are one of the common causes for incorrect file associations on your windows system. It is highly recommended that you check your registry for file association errors (will also check for any other registry errors).
The AZW file type is primarily associated with 'Kindle' by Amazon.com, Inc..
Amazon Kindle is an electronic book (e-book) device by Amazon.com.
It uses an electronic paper display, reads the proprietary Kindle (AZW) format, and downloads content over Amazon Whispernet, which uses the Sprint EVDO network.
Cannot access AZW files on windows?
When windows gives you an error message saying that it "Cannot open AZW files", this means either:
A. You need to indentify a program that can open the file B. Or your registry may be damaged
RECOMMENDED:
In both cases it is strongly recommended that you run a free scan for registry errors.
