How to Clean the Windows Registry by Hand New York

As your registry grows in size, your operating system's performance may be compromised. Third-party registry cleaners may not have the best logic and algorithms to effectively clean all registries. They perform cleaning tasks based upon a predefined set of rules that may not work in your registry, or even a healthy registry, let alone a bloated or corrupted registry.Fortunately, you can clean your registry manually to remove leftover application entries after uninstalls and unnecessary start-up items.

Steps

Launch the Windows registry editor.
1. Click on the "Start" button, then select "Run...".
2. Type regedit inside of the text box.
3. Press "Enter" or click on "Ok".
Backup your existing registry before making changes. This will offer a way to undo the changes you make if they negatively impact your operating system or installed software. (See related articles on how to backup your registry. A registry backup is really a critical step, and should be undertaken immediately before beginning any editing of you registry).
1. Click on the "File" menu and select "Export".
2. Select "All" in the "Export range" panel.
3. Choose a location for the backup and then enter a name.
4. Click on "Save".
Familiarize yourself with the registry editor. It is broken into two window panes, with the left pane used to show the entire registry tree and the right pane used to show individual values.
Browse to remove old applications. Remove any application listings which have already been uninstalled.
1. Expand the "HKEY_CURRENT_USER" key (looks like a folder) by clicking on the plus (+) sign next to it.
2. Expand the "Software" key.
3. Look for keys that contain either the application's name, or more commonly, the application's developer (company name).
4. Highlight a key for the application.
5. Press "Del" to delete it.
Search applications by their name, executable name, and/or folder name. Remove any application listings which have already been uninstalled.
1. Press "Ctrl" and "f" to open a find dialog.
2. Enter the text used to search for the application's listings.
3. Click on "Ok" to search. The key or value should be highlighted when found.
4. With the proper key or value highlighted, press "Del" to delete it.
5. Press "F3" to find the next result and repeat.
Remove unwanted start-up items. Many of the more popular applications, such as Adobe Reader, Quicktime Player, and Real Player, will install a registry value to load an updater or similar process when Windows starts. To delete these:
1. Expand keys (as done previously) to get to the following location: My Computer\ HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows\ Current Version.
2. Highlight the "Run" key.
3. Look for values inside of the left pane. These will be shortcuts to executable files.
4. Highlight a value to remove. If you're not familiar with these, or are unable to guess which ones correlate to which applications, Google for it or use a process search engine such as Process Library
5. Press "Del" to delete it. To select multiple entires to delete, hold down "Shift" or "Ctrl" while clicking.
6. Repeat this process for the same key path inside of the HKEY_CURRENT_USER location as well. If an application installs for "all users", it will put these startup items inside of the the local machine folder. For current user or single user software installs, they will be put into the current user folder.
Close the registry editor when finished.

Tips

Press the letter the software started with to get there faster if you know its name
If anything goes wrong, restore your registry with the backup you made. This can be done by opening the backup file directly (ie: double-clicking on it), or using a Windows installer CD to boot to a "recovery" console and restoring it manually.

Warnings

Editing the registry with the built-in Windows Registry Editor can be a risky endeavor. There is no "undo" functionality if you happen to accidentally delete the wrong key or value.
Do not edit your registry if you are not comfortable with the process. If you do edit it, be sure to have a backup of it on file. When in doubt, don't delete an entry. Instead, research it online to find out the purpose of any individual key or value.
