Windows10 seems to have a key logger enabled by default. The option says “Send Microsoft info about how I write to help us improve typing and writing in the future” and unlike Google Dashboard, there seems to be no option to delete your content that Microsoft has collected so far. Disabling it only prevents the collection of your typing after the option has been disabled.

To check or disable the key logger:

Click on Start, select Settings:

On the Windows Settings screen click Privacy (lock icon):


General is already selected, if not, click it:


Make sure this option is turned Off:


Good Luck!
