I've had this problem for the last 6 months, maybe longer. When I try to shut off my laptop(windows key, and then click shutdown), nothing happens. Sometimes in like 5 or 6 minutes it does shut off. Most of the time it never shuts off.
The only way I have found to shut it off in a controlled manner is to pause the protection for 1 minute on my kaspersky. Shutting off kaspersky all together is also a possibility. From the moment kaspersky is blocked my computer starts turning off immediately.
Why can't my surface book shut off with Kasperky running? Somehow Kaspersky is blocking my system to turn itself off.
