While many people refuse to agree, the fact is that registry cleaners are pointless and should not be used. Perhaps back on Windows 95 with dirt-slow hard drives, it made sense. Use Google Fonts in Word. Customize the Taskbar in Windows What Is svchost. Best Home Theater Systems. Best Smartwatches.

Second, if you do make a silly mistake, there's no easy way to undo Registry edits. Before you delete or edit a value, it's a good idea to back it up by right-clicking on the key in the Registry Editor and selecting Export.
This will save a backup file with a REG extension containing all the data within that key; if you repent of your changes, you can just double-click on the REG file to import the old settings. To back up the entire Registry, click on Computer at the top of the tree and select Export.
DEFAULT this contains many default settings that are applied for new users, so you may be able to copy values from here to restore your own account to default behaviour. There are many freely downloadable, third-party apps out there that offer an easy way to apply Registry hacks, and customise Windows in other ways. If you're nervous about getting hands-on with the Registry then such a tool might suit you nicely. However, these programs have to contend with the fact that Windows is a moving target, and tricks that work in one version might not work in the next.
The hacks we recommend below have all been tested on the latest edition of Windows 10, and most will work on older releases, too. Be more sceptical of tools that claim to find and fix Registry errors. These apps usually focus on removing references to applications and resources that have been deleted. They won't do you any harm, but it's unlikely that they'll fix any serious problems, and they almost certainly won't be able to help you out if you have manually changed a setting you shouldn't have.
It's a similar story with Registry compacting tools. It's true that the Registry takes up space on your hard disk, and parts of it are cached in RAM, so clearing out superfluous data will give you more free disk space, and more available memory. However, by modern standards the hive files are very modestly sized typically less than MB on a single-user system so compacting them is unlikely to make a noticeable difference.

Why might I want to edit the Registry directly? By tweaking the Registry you can add a time-saving "Take Ownership" option to the Explorer context menu Sometimes these options have been hidden away because they're too complex to bother users with.
The Structure of the Registry. The Registry has a hierarchal structure, although it looks complicated the structure is similar to the directory structure on your hard disk, with Regedit being similar to Windows Explorer.
There are six main branches, each containing a specific portion of the information stored in the Registry. They are as follows:. Each registry value is stored as one of five main data types:.
Other data types not available through the standard registry editors include:. EXE is included with most version of Windows although you won't find it on the Start Menu it enables you to view, search and edit the data within the Registry. There are several methods for starting the Registry Editor, the simplest is to click on the Start button, then select Run , and in the Open box type "regedit", and if the Registry Editor is installed it should now open and look like the image below.
Create a Shortcut to Regedit This can be done by simply right-clicking on a blank area of your desktop, selecting New, then Shortcut, then in the Command line box enter "regedit. Using Regedit to modify your Registry Once you have started the Regedit you will notice that on the left side there is a tree with folders, and on the right the contents values of the currently selected folder.
To display the contents of a key folder , just click the desired key, and look at the values listed on the right side. You can add a new key or value by selecting New from the Edit menu, or by right-clicking your mouse. And you can rename any value and almost any key with the same method used to rename files; right-click on an object and click rename, or click on it twice slowly , or just press F2 on the keyboard. Lastly, you can delete a key or value by clicking on it, and pressing Delete on the keyboard, or by right-clicking on it, and choosing Delete.
Note: it is always a good idea to backup your registry before making any changes to it.
