It's there What to expect from the Windows 10 Fall Creators Update | ZDNet
The Fall Creators Update also debuts an anti-ransomware feature called Controlled Folder Access, which is also available through the Windows Defender Security Center. When this feature is enabled, only approved apps can access Windows system files and data folders. (You can customize the list of data folders and whitelist specific apps.)
When Microsoft first launched the Windows Store back in 2012, it imposed a limit on the number of devices a single Microsoft account could install Store apps on. Originally, this number was a measly five, but that was increased to 81 a year later before being decreased to ten with the launch of Windows 10. Now, it seems Microsoft has had yet another change of heart, as the device limit has increased to 2,000.
Microsoft is now planning to let Windows 10 Fall Creators Update users access the full privacy statement during setup. While most people never read this full statement, there will be a “learn more” section for each privacy setting during setup, allowing people to better understand settings without reading the full privacy statement.
