# Fix WPA Registry

- In some cases, system may have corrupt WPA registry keys `HKEY_LOCAL_MACHINE\SYSTEM\WPA` which can cause `sppsvc` to not work and activation will fail.

- The activation scripts in MAS can detect this issue and will inform you accordingly when to run this option. We suggest to run this only when script asks you to do it. If you are not sure if you need to do it, you can take the help from here.

- This registry key is protected by the Kernal and can not be deleted normally. That is why we need to follow some more below steps to clear it.
