Hazar's RemoveWAT will not work with Windows 8
It is suspected that this hack is broken by Microsoft's update KB971033 and possibly Windows 7 Service Pack 1.
You don't need to apply this hack as well as the Daz Loader - both are supposed to defeat the Microsoft activation of Windows 7. You do, however, have to apply these "cracks" to "clean" copies of Windows, i.e. copies that don't have other activation circumventing changes and software run on them - in these cases the other hacks need to be un-installed before the Daz or the Hazar solutions will work.
running the RemoveWAT fix maybe different to running RemoveWAT. RemoveWAT by Hazar is a program that removes/disables Windows Activation Technologies - it does not fix a previous attempt at activation.
What Microsoft say:
When this update is installed, it performs a validation process for the copy of Windows that is running on your computer. However, this validation process does not affect the functionality of Windows. The update process exits silently if it detects no validation errors, activation exploits, or tampered files.
