Sad news for all the folks who use Dropbox but are still, for some reason, using Windows XP: the company is making moves to end support for the 14-year-old operating system in a phase by phase fashion.

According to Dropbox, the beginning of the end for Windows XP support will start June 26. This is when the desktop app for the operating system will cease to work. Furthermore, it will no longer be available for download via Dropbox.com. The ability to sign in to the service’s web browser with Windows XP will be scrapped, but if you’re already signed in, Dropbox will keep you logged in until August 29, 2016.

What’s the reason for Dropbox’s need to end support for Windows XP? The reason is simple really: Windows XP is just too old and to make matters worse, Microsoft itself dropped support two years ago, so there’s little reason for any company to continue doing so. Additionally, Dropbox says it is working on new software and it will include performance and security improvements.

To deliver these things, users must be running a modern operating system such as Windows 7 up to Windows 10. Should users decide to be brave and continue down the path Dropbox doesn’t want them to go, they will lose access to all their files until a new and modern operating system does come into play. As it stands right now, Windows XP users have little choice in the matter.

At the moment, Windows XP accounts for 11% of the operating system market. That’s a huge number when one considers the fact that the OS is 14-years-old and counting.

We recommend users upgrade to Windows 7 then take advantage of the free upgrade to Windows 10 before the offer is no longer available.
