A recent study analyzed the vulnerabilities in Microsoft Windows for all of 2013. What the study found was that 92% of those vulnerabilities could be eliminated by removing administrative rights for users.

According to an analysis by privilege management firm Avecto, eliminating admin rights can also remove 96% of critical vulnerabilities affecting Windows OS, 91% on Microsoft Office, and a total 100% on Internet Explorer browser.

It is clear that removing admin rights from end users is not only prudent, but an absolute necessity when it comes to securing your network, and greatly decreasing the likelihood that your users will be affected by viruses and malware.
