A security descriptor can be stored as part of an object's metadata in an operating system, such as in the file system for files and folders or in the registry for registry keys. It contains information about the security attributes of the object, such as the owner, permissions, and auditing settings.
There are five root keys.
you can find and edit registry keys by pushing Windows Key+R, typing regedit and hitting enter. registry keys are the settings for your operating system and all your programs. i would recommend not screwing around with them, it could really mess up your system.
Registry Contents • The Registry is hierarchical in structure - Made up of keys, subkeys, and entries • Registry key - A category or division of information within the Registry • Registry subkeys - A single key may contain one or more lower-level keys • Registry entry - A data parameter associated with a software or hardware characteristic under a key (or subkey)
On a local PC you can have an access to registry settings through registry editor. It allows you to have a low-level access to system settings and export them to .reg file. Using registry editor you even can access to registry on a remote computer. But registry editor wasn't designed to work with multiple remote PCs simultaneously. If you need to export registry keys from multiple PCs, you can benefit from the features of EMCO Remote Registry Exporter. EMCO Remote Registry Exporter is a tool that was designed to work in the network environment to export registry keys from one or multiple remote PCs. It can be used it if you need to check registry data on remote PCs or backup specified registry keys. Registry keys and values are extracted by the application from remote PCs and are stored in .reg files, created for every PC, so you can use them to find required information or use later on to restore registry settings. To initiate remote registry export operation you only have to define a list of keys to export and a list of PCs where export should be performed
