so what’s a batch file solution to this then? I’ve got a batch file to start Steam maintenance process, another to automatically play whatever CD is in my disk drive, how do i go about making one to re-add a Dword to Windows Defender and set its value to “1”?
ric says
windows deletes the dword 32 DisableAntiSpyWare after a while
i think its because of the updates. i’ve done this before with older version of windows 10 didn’t had this problem
Pita says
Keeps deleting key on restart

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.

Thanks for the additional feedback, really appreciate. Thanks

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.

Thanks for the great input, really appreciated.

You mean enter “1” to disable WD.
