Q: iTunes wont startup!

Hello there, MrLuck1.

It sounds like you're unable to launch iTunes on your computer that is running Windows 7. The following Knowledge Base article provides some great steps for troubleshooting:

Fix unexpected quits or launch issues in iTunes for Windows - Apple Support

If iTunes for Windows Vista or later won't open, stops responding, or unexpectedly quits, follow the steps below to resolve the issue.

• If you're using Windows XP, learn how to fix unexpected quits, freezes, or launch issues.
• If you have issues installing iTunes, or iTunes fails to open and you see an Error 7 or Error 2 alert message, learn what to do if you can't install or update iTunes for Windows.
• If the issue only occurs when an iOS device is connected, learn what to do if iTunes become unresponsive when you connect an iPhone, iPad, or iPod touch.

Before you start, download and install the latest available Windows updates for your PC and make sure that you have the latest version of iTunes.

Start iTunes in Safe Mode

When you open iTunes in Safe Mode, you isolate the program from any interference caused by plug-ins or scripts not manufactured by Apple. To start iTunes in safe mode, hold down the Shift and Control keys on your keyboard while you open iTunes.

You'll see a message as iTunes is starting that says "iTunes is running in Safe Mode. Visual plug-ins you have installed have been temporarily disabled."

If the issue doesn't happen in Safe Mode, remove any third-party plug-ins.

Disconnect your computer from the Internet

Errors communicating with the iTunes Store and other Apple services can sometimes cause issues with iTunes startup. If you remove the ability to connect to those services, you can see if those features have issues that need to be resolved.

1. Disconnect your computer from the Internet. For example, turn-off WiFi or unplug your ethernet cord.
2. Open iTunes.

If iTunes opens with no issues, update your drivers. If there's still an issue, contact Apple Support for help with isolating any errors. 

If there's still an issue, continue below.

Create a new user account

Visit the Microsoft website to learn how to create new user accounts for Windows 8, Windows 7, or Windows Vista or Windows XP.

If you have the same issue in the new user account, skip to System-wide issues. If you don't experience the same issue, continue to User-specific issues.

Thanks for reaching out to Apple Support Communities.

Cheers.
