I'm running Win8.1 Embedded on a small board computer, with a 16gb drive (it's built-in, can't replace it). It's an almost clean install, and the Winodws folder just keeps growing and is now 14gb. I'm pretty sure Windows Embedded should not be that big, I uninstalled almost all of Windows features and that made no difference.
Any ideas what is going on, and how to prevent Win8.1 Embedded to grow and eat my entire drive?
Thanks.
cleanmgr
in Windows and remove everything you think, you won't need. This does not harm your Windows installation, but usually removes the feature to uninstall updates for instance.
