I cannot find updates for itunes for windows

Greetings rjkr,

You can use these steps to update iTunes:

"Check for iTunes updates from the iTunes Download page

If you install iTunes from the iTunes Download page, you can manually check for updates to iTunes, or set iTunes to check for new versions automatically every week. 

In the iTunes app  on your PC, do one of the following:

• Manually check for new versions of iTunes: Choose Help > Check for Updates.
• Have iTunes automatically check for new versions every week: Choose Edit > Preferences, click Advanced, then make sure the “Check for new software updates automatically” is selected.

When automatic updating is turned on, iTunes checks for new updates weekly. It checks only after you have quit and restarted iTunes at least once during a seven-day period." Update iTunes on PC

We hope this helps!

Sincerely.

If you have installed iTunes from the Microsoft Store, the update process is fully automatic. As far as I know there is no option to check for updates in the Microsoft Store version.

So if you look in the Help menu on iTunes' top bar but there is no option to Check for Updates, that suggests to me that you have the Microsoft Store version.
