1. Make sure you have an administrator account.
   To install iTunes, you'll need to log in to your computer with an administrator password. If you're not sure if you have an administrator account, read Windows 7: How do I log on as an administrator? You could also refer to your computer's help system, contact your IT department, or visit support.microsoft.com for assistance.
   
2. Install the latest Microsoft Windows updates.
   To download the latest updates, visit the Microsoft Windows Update website. iTunes for Windows requires Windows XP, Windows Vista, Windows 7, or Windows 8 with the latest Service Pack installed. If you can’t install the updates, refer to your computer's help system, contact your IT department, or visit support.microsoft.com for assistance.
   
3. Download the latest version of iTunes.
   The latest version of iTunes can be downloaded at http://www.apple.com/itunes/download/.
   
4. Repair a previously installed version of iTunes.
   If iTunes is already installed on your computer:
   • Search for iTunesSetup or iTunes64Setup on your computer.
   • Right click on the file.
     • Windows Vista, Windows 7, and Windows 8: Choose "Run as administrator."
     • Windows XP: Choose Open.
   • Click and follow the wizard to repair iTunes.
     
5. Remove iTunes from your computer.
   Remove and reinstall iTunes and other software components for Windows XP
   Remove and reinstall iTunes and other software components for Windows Vista, Windows 7, or Windows 8
   Songs you bought from the iTunes Store or imported from CDs are saved in your My Music folder by default. They won't be deleted by removing iTunes.
   
6. Disable conflicting software.
   Some Windows background processes can cause issues for other programs and processes. These conflicts can prevent applications, such as iTunes, from installing. Disable conflicting processes by starting your computer using MSConfig:
   • Using Msconfig to troubleshoot conflicts in Windows XP
   • Using Msconfig to troubleshoot conflicts in Windows Vista, Windows 7, and Windows 8
   Some security software made by other companies can't be disabled using MSConfig. If you've installed security software and you're having issues installing iTunes or QuickTime for Windows, you might need to disable or uninstall security software to resolve installation issues.
   
7. Restart your computer.
   
8. Install iTunes.
