kennysarmy Posted Monday at 08:20 Posted Monday at 08:20 Starting to see random shutdowns on our PC's so raised a ticket this morning. Hi Jeff, Thank you very much for your email. Please be assured that we will immediately start to investigate this problem. We haven’t got into this yet, but this problem would seem superficially similar to a problem reported by another customer on Friday. This was caused by a new Windows update which has subtly changed (e.g. broken!) the security model for Windows power policies. If this is the case, we have a fix already in the works.
kennysarmy Posted Monday at 08:41 Author Posted Monday at 08:41 NB: This problem is caused by Windows Update released in September 2026. It changes the settled default Windows power policy security settings which have been present since Windows Vista (19 years ago). The problem is likely to occur with all versions of PowerMAN since 2008 including the current beta. In 18 years of PowerMAN this is the first time this has happened. We take this very seriously and have a preliminary fix currently in testing.
