Apple:

Starting May 25, Apple will introduce security changes that prevent older Windows PCs from using the iTunes Store. If you have Windows XP or Vista PC, your computer is no longer supported by Microsoft, and you’re not able to use the latest version of iTunes.

You can continue to use previous versions of iTunes on your Windows PC without support from Apple. However, you won’t be able to make new purchases from the iTunes Store or redownload previous purchases on that computer. […]

Also beginning May 25, security changes will prevent Apple TV (1st generation) from using the iTunes Store. This device is an obsolete Apple product and will not be updated to support these security changes.

I have Snow Leopard installed on an external hard drive that I’ve connected to an old iMac. The version of iTunes on that drive is still compatible with Requiem, which let’s me remove the DRM from movies and TV shows purchased from the iTunes Store. From there, I can transfer the DRM-free video files into Plex — my preferred media playback app.

But I suspect this will no longer be possible when Apple flips the switch on May 25. And once again, I’ll be stuck watching newly purchased iTunes content in Apple’s apps.
