Utorrent Registry Entries

[Viola Mathenia]

Acentral hierarchical database used in Windows 98, Windows CE, Windows NT, and Windows 2000 used to store information that is necessary to configure the system for one or more users, applications, and hardware devices.

The Registry contains information that Windows continually references during operation, such as profiles for each user, the applications installed on the computer and the types of documents that each can create, property sheet settings for folders and application icons, what hardware exists on the system, and the ports that are being used.

The Registry replaces most of the text-based .ini files that are used in Windows 3.x and MS-DOS configuration files, such as the Autoexec.bat and Config.sys. Although the Registry is common to several Windows operating systems, there are some differences among them. A registry hive is a group of keys, subkeys, and values in the registry that has a set of supporting files that contain backups of its data. The supporting files for all hives except HKEY_CURRENT_USER are in the %SystemRoot%\System32\Config folder on Windows NT 4.0, Windows 2000, Windows XP, Windows Server 2003, and Windows Vista. The supporting files for HKEY_CURRENT_USER are in the %SystemRoot%\Profiles\Username folder. The file name extensions of the files in these folders indicate the type of data that they contain. Also, the lack of an extension may sometimes indicate the type of data that they contain.

The registry in 64-bit versions of Windows XP, Windows Server 2003, and Windows Vista is divided into 32-bit and 64-bit keys. Many of the 32-bit keys have the same names as their 64-bit counterparts, and vice versa. The default 64-bit version of Registry Editor that is included with 64-bit versions of Windows XP, Windows Server 2003, and Windows Vista displays the 32-bit keys under the node HKEY_LOCAL_MACHINE\Software\WOW6432Node.For more information about how to view the registry on 64-Bit versions of Windows, seeHow to view the system registry by using 64-bit versions of Windows.

Before you edit the registry, export the keys in the registry that you plan to edit, or back up the whole registry. If a problem occurs, you can then follow the steps in the Restore the registry section to restore the registry to its previous state. To back up the whole registry, use the Backup utility to back up the system state. The system state includes the registry, the COM+ Class Registration Database, and your boot files. For more information about how to use the Backup utility to back up the system state, see the following articles:

Administrators can modify the registry by using Registry Editor (Regedit.exe or Regedt32.exe), Group Policy, System Policy, Registry (.reg) files, or by running scripts such as VisualBasic script files.

We recommend that you use the Windows user interface to change your system settings instead of manually editing the registry. However, editing the registry may sometimes be the best method to resolve a product issue. If the issue is documented in the Microsoft Knowledge Base, an article with step-by-step instructions to edit the registry for that issue will be available. We recommend that you follow those instructions exactly.

Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

The navigation area of Registry Editor displays folders. Each folder represents a predefined key on the local computer. When you access the registry of a remote computer, only two predefined keys appear: HKEY_USERS and HKEY_LOCAL_MACHINE.

Microsoft Management Console (MMC) hosts administrative tools that you can use to administer networks, computers, services, and other system components. The Group Policy MMC snap-in lets administrators define policy settings that are applied to computers or users. You can implement Group Policy on local computers by using the local Group Policy MMC snap-in, Gpedit.msc. You can implement Group Policy in Active Directory by using the Active Directory Users and Computers MMC snap-in. For more information about how to use Group Policy, see the Help topics in the appropriate Group Policy MMC snap-in.

Create a Registration Entries (.reg) file that contains the registry changes, and then run the .reg file on the computer where you want to make the changes. You can run the .reg file manually or by using a logon script. For more information, see How to add, modify, or delete registry subkeys and values by using a Registration Entries (.reg) file.

The Windows Script Host lets you run VBScript and JScript scripts directly in the operating system. You can create VBScript and JScript files that use Windows Script Host methods to delete, to read, and to write registry keys and values. For more information about these methods, visit the following Microsoft Web sites:

Windows Management Instrumentation (WMI) is a component of the Microsoft Windows operating system and is the Microsoft implementation of Web-Based Enterprise Management (WBEM). WBEM is an industry initiative to develop a standard technology for accessing management information in an enterprise environment. You can use WMI to automate administrative tasks (such as editing the registry) in an enterprise environment. You can use WMI in scripting languages that have an engine on Windows and that handle Microsoft ActiveX objects. You can also use the WMI Command-Line utility (Wmic.exe) to modify the Windows registry.

To restore registry subkeys that you exported, double-click the Registration Entries (.reg) file that you saved in the Export registry subkeys section. Or, you can restore the whole registry from a backup. For more information about how to restore the whole registry, see the Method 2: Restore the whole registry section later in this article.

To restore the whole registry, restore the system state from a backup. For more information about how to restore the system state from a backup, see How to use Backup to protect data and restore files and folders on your computer in Windows XP and Windows Vista.

Data Protection Manager (DPM) is a key member of the Microsoft System Center family of management products and is designed to help IT professionals manage their Windows environment. DPM is the new standard for Windows backup and recovery and delivers continuous data protection for Microsoft application and file servers that use seamlessly integrated disk and tape media. For more information about how to back up and restore the registry, see How to back up and restore the registry in Windows XP and Windows Vista.

Unless you were monitoring / auditing the registry when you installed the program (and assuming the happy scenario the program didn't add registry keys at runtime, if so you would need to monitor the registry from start to finish), the program might have added keys to the registry in non-obvious places.

Most programs add their registry keys in the HKEY_CURRENT_USERS\Software or in HKEY_LOCAL_MACHINE\Software in a dedicated branch (I'm looking at wxMaxima, for instance, located in the first path). If you deleted the corresponding branch you could in theory delete all keys associated with the program. However, some programs might alter something somewhere on the rest of the registry, and that doesn't have a good rule of thumb.

If, on the other hand, you did monitor everything, then reversing the changes is trivial (because you know what were they). I suppose you could reinstall the program on a virtual environment and monitor there. In theory you would receive the same results.

I found 375 keys yesterday but I do not have permissions to edit or remove them. I am a local admin on the machine and am the user who installed the application in the first place. I am also running regedit as an administrator.

There are a few ways to create corrupt Registry Keys. It could be a bad install of the program, it could be an upgrade of existing software that has failed, it could be OS corruption, it could be a faulty hard drive, RAM or even the CPU.

Failing all that, I think you said there were 200+ registry keys found by REVO Uninstaller, so that sounds like a lot of time that no one will want to pay for. Is it possible to nuke and pave? Just format the drive and reinstall Windows.

The Windows Registry is a hierarchical database that stores low-level settings for the Microsoft Windows operating system and for applications that opt to use the registry. The kernel, device drivers, services, Security Accounts Manager, and user interfaces can all use the registry. The registry also allows access to counters for profiling system performance.

In other words, the registry or Windows Registry contains information, settings, options, and other values for programs and hardware installed on all versions of Microsoft Windows operating systems. For example, when a program is installed, a new subkey containing settings such as a program's location, its version, and how to start the program, are all added to the Windows Registry.

When introduced with Windows 3.1, the Windows Registry primarily stored configuration information for COM-based components. Windows 95 and Windows NT extended its use to rationalize and centralize the information in the profusion of INI files, which held the configurations for individual programs, and were stored at various locations.[1][2] It is not a requirement for Windows applications to use the Windows Registry. For example, .NET Framework applications use XML files for configuration, while portable applications usually keep their configuration files with their executables.
