Starting with Windows Vista, Microsoft implemented the User Account Control feature, or just UAC. This feature is designed to improve the OS security. The side effect of this feature is that mapped network drives are inaccessible to programs running as administrator. e.g. if you start the app Total Commander elevated, it won't see your mapped drives. This can be a major inconvenience especially if you run apps as admin regularly. In this article, we will see how to enable access to mapped network drives from elevated apps.
