    Thanks a million for this, it worked beautifully. My input:
    1- followed literally your post with defender on and rebooted, it didn’t work.
    2- repeated it with deactivating defender value (1) and rebooted, this enabled me to access system scan options that wasn’t available before.
    3- I chose “Scan windows defender (last option), it rebooted, worked on it and rebooted windows with problem solved.

    Can’t thank you enough buddy.

    The input value you provided for both the “enable” and “disable” methods are the same. Also, would it be detrimental to delete the WD file from the registry? Anyone interested in privacy can also disable Cortana by same path mentioned in article but following: Windows Search/Allow Cortana, and set value to 0. Also Microsoft/SQMCClient/Windows, click CEIPEnable, set value to zero. Microsoft collects your data through these, including a built in keyloggers in Windows 10.
