You weren't imagining it: Windows 11's slow shutdowns are finally fixed

The issue stemmed from the Background Intelligent Transfer Service (BITS) taking excessive time to shut down properly. Users must manually install this optional update to immediately benefit from faster shutdowns and improved Bluetooth functionality. If you've been a Windows user for many years and always shut down your PC properly, you'll no doubt have a sense of how quickly this process should actually take. Recently, however, some Windows 11 users have noticed that shutting down takes a few seconds longer than usual. This isn't an individual problem with your system, but a bug that can affect many users. Microsoft has now officially confirmed the issue, with June's optional update KB5095093 intended to fix it. According to the update's support page, Microsoft has identified a fault in the Windows BITS service, which transfers files in the background and automatically resumes downloads if they're interrupted.
