Every time you install a software on Windows, you  must have noticed that by default they are all installed to "Program Files" folder of your root directory.
So if you are running out of space in your root directory, you would always want to change this software installation path and here's how you can achieve it in Windows operating System

For changing these settings you have to modify some parameters in Windows Registry as outlined below -
  1. Make sure you backup your registry before making any changes to it.
  2. Navigate to following folder in registry - HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion.
  3. Look for the entry "ProgramFilesDir" in panel on right side.
  4. Change its value from "C:\Program Files" to D:\Installation (or whatever else you wish it to be).



Press PF5 for refreshing the registry updates and restart your machine for change to take effect.
So now every time you install new software they would get installed to this new folder of your choice.

The Commands you enter in "Run" dialog box from start menu in Windows operating system are automatically cached to help you later with Auto-complete.
One can play around with these entries - delete, add your own, etc. as these are stored in cached list inside windows registry.

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
  2. One you click on RunMRU folder, on right side you will find entries for the Most recently used command in Run box.

You can now, delete the unwanted entries, add some of your own or just play around with it.

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.

Restore
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.
