So in-order to edit these entries you need to open Windows registry, and follow the instructions below

  1. Go to HKEY_CURRENT_USER/Software/Microsoft/Windows /CurrentVersion/Explorer/RunMRU on left browse panel

The registry is critical for health of the system, sometimes even a small tweak, may corrupt windows registry and prevent you from logging in.
So it is always recommended to back up the Registry before applying any of your changes. This is how you do it -

To take the back up of the registry open registry editor from start > Run, type Regedit and press enter.

Export registry

In Registry editor, under browse panel, select the highest key, which is wither "Computer" or 'My Computer' depending on version of your Windows OS and then from top level menu in registry editor select File > Export, give the location where you want to store the back-up, and its done - backup of complete registry.

One can also do selective backup for a particular key, it can be done in same way - just select that key you needs to be backed up from left browse panel and then click on top-level File menu > export, this would just backup the selected key.
The registry backup files are stored as ".reg" files.

To restore from backup again you can simply double click the backup file, or in Regedit, click on File menu > import from Registry editor.

Alternatively, users using Windows ME and higher can also create system restore points, to save all the current settings of windows (including registry). To do this navigate to start > program > Accessories > System Tools > System Restore, and select 'create a restore point'. To revert to this point later, you have to just select the point again to restore.

The registry is the place where windows stores all the settings related to hardware that it controls, software installed and other windows environment settings; like toolbar, colors, menus, etc. So to apply our own customized settings, registry editing is must.

To open the registry go to 'start menu' > run then type regedit and press Enter.

Then registry editor opens, where the left pane has folder tree like hierarchy. Each item here is called Key and they may again have further sub-keys. When you select a key you will find some items in right pane. These are entries corresponding to selected keys. It is the entries that store the settings. Entries can store three types of data: String, Binary and DWORD.

To create a new key just right click the parent key and select New > Key. to create an entry select the key in left pane, right-click over in right pane and select the data type of the entry to be created. The changes to registry may not be effective right then and there; sometimes it may need Restart or log-off or simply pressing function key F5 (refresh) will apply the customizations. For particular software changes, sometimes only restarting the application will work.
