We have had several users request support for hyperlinks not working from Office programs. They click on a link in an email and they get an error message: "This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator."
After quite a bit of investigation we determined this was caused by Chrome web browser being uninstalled while it is still set as the default web browser.
The short answer: While logged in as the user, with Office programs closed, install Chrome. Then set the default browser to Internet Explorer, uninstall Chrome, and reboot.
What bothers me about this scenario is the user doesn't need to have privleges to install Chrome. I have tested this with a basic user account on Windows 7 32 bit. The user is not able to install or uninstall programs. (Tested using Dymo Label Software v8 and Adobe Acrobat Reader X) However, browsing to https://www.google.com/chrome/browser/ and clicking on the Download button will allow Chrome to install.
