Failed to connect to a windows service

[Der Meister]

Windows could not connect to the System Event Notification service. This problem prevents standard users from logging on to the system. As an administrative user, you can review the System Event Log for details about why the service didn't respond.

Това ми се изписва като си пусна компа. Появи се след като windows-а ми изписа, че иска activation key и се наложи да сложа това нещо - http://zelka.org/details.php?id=328579
Не знам дали има някаква връзка
