Windows® Registry Data Set It is possible to compile a historical list of applications based on RDS metadata and residue files. Many methods can be used to remove application files, but these may not purge the Registry. Examining the Registry for residue can augment a historical list of applications or provide additional context about system use. Windows® Registry Data Set (WiReD) The WiReD contains changes to the Registry caused by application installation, de-installation, execution or other modifying operations. The applications are chosen from the NSRL collection, to be of interest to computer forensic examiners. WiReD is currently an experimental prototype.

  • Windows Registry,Some Basic Understanding
    WINDOWS REGISTRY,SOME BASIC UNDERSTANDING For the peoples who use Windows, „Windows Registry‟ is not a new word at all. The registry is a central database of all configuration settings for most of the applications installed on the computer. Windows stores all its settings in this „Registry‟ itself. The „Windows Registry Editor‟ allows us to configure many hidden settings for windows and other applications installed, which are not accessible by the interface of the particular software itself. You can easily manipulate and modify the values of registry and improve the PC‟s performance. However, do it carefully, because modify the right setting and your computer gets a boost, modify the wrong one and you end up with a non-booting system. In my previous post I wrote about „Autoruns‟, it can also manipulate registry. (Read here) To edit registry, we can use „Windows Registry Editor‟, which is preinstalled in Windows itself. It can be launched by using the command „regedit‟ in the „RUN‟ dialog box, which can be launched by pressing “Windows key+R”. On start-up, „Windows Registry‟ will show up the following five root entries. HKEY_CLASSES_ROOT HKEY_CURRENT_USER HKEY_LOCAL_MACHINE HKEY_USERS HKEY_CURRENT_CONFIG All the settings given above are not stored in a single file. They are spread across multiple files in logical groups called „hives‟. The combination of hives makes „Windows Registry‟. The values are stored here in binary format. That means only “1” and “0” is used here. “1” means “yes”, whereas the value “0” represents “no”. Let us look into the details of these settings. 1. HKEY_CLASSES_ROOT: It is abbreviated as HKCR.
