Windows and any relevant updates or service packs come with uninstall files that remove the applications from the computer. Many of these files are very large and take up a great deal of space on a computer's hard drive. If you are confident that you will never want to uninstall Windows or its updates, you can save considerable hard disk space by deleting the uninstall files.
Right-click the "Start" button and open Windows Explorer.
Click "Tools" from the menu ribbon at the top of Explorer and select "Folder Options." Click the "View" tab and select "Show hidden files or folder" in the "Advanced Settings" menu.
In the left-hand panel of Windows Explorer, access the "Windows" folder on the hard drive partition on which Windows is installed (e.g., C:\\Windows or D:\\Windows).
Select all folders labeled "$NtUninstall," "$MSI31Uninstall" or "$NtServicePackUninstall" by holding down the "Ctrl" key and clicking each folder.
Delete the selected folders by right-clicking any of the selected files and choosing "Delete" from the pop-up menu or pressing the "Del" key. Permanently delete the selected files by emptying your computer's recycle bin.
- Make a backup copy of all uninstall folders or files if you think you might ever want to uninstall Windows or one of the service packs.
