  1. Followed the receipt, but was still not allowed to change the regkey setting. So ran regedt32 from a different computer and accessed the registry over the network. Voila!

  2. Worked like a charm! I couldn’t make changes to my registry either, but this part worked perfectly,

    •Start -> run and type MSCONFIG
    •Under services and uncheck TrendMicro Unauthorized Change Prevention Service

    Thanks!
