Steps to install the new definitions for Windows Defender

[Guest]

There is a serious bug in updating this beta software. First uninstall the
old defintions by clicking start then run and typing Msiexec /x
{A5CC2A09-E9D3-49EC-923D-03874BBD4C2C} (paste it in your box not to make
errors...). If you didn't try to install the new ones before putting your PC
off and turning it on, this should work. Next step is opening Windows
Defender and updating through the button check for updates in the about
section of the help. Let's hope the Microsoft team will solve the problem
with autoupdate and installing through it soon.

I followed the steps I get a message "this action is only valid for products
that are currently installed OK" I ran Windows update and had 2 new downloads
but nothing for defender I still get error 0x800b0003
