For example, over the last few years working as an IT Professional, there have been many occasions where it has been proven very useful to disable the firewall in Windows, to disable the popup blocker in IE or to disable the autorun/autoplay feature for the CD/DVD drive.ĭisabling items such as regedit, task manager, hardware devices, cookies, etc should only be performed if there are other people who use your computer and you want to prevent them from accessing system settings. Even though most people never change the settings on their computers, there are some situations where it’s very useful to be able to turn off or disable a certain program, service, or setting in Windows 7 or Windows 8.
