Windows 8.1 Pro x64 UEFI very slow boot and shutdown

any fix on this issue?

been experiencing this also.. anf also the 100% disk usage, i hope microsoft release updates

I was doing some checking with msconfig and even disabling everything my shutdown is over 4 minutes.  However, at one point I got into a weird startup where I think some of the Microsoft items did not load.  Had a couple of things I noticed in that configuration.  1 was that the computer would not see any network but would connect to the network.  The other item I had was a warning that said:  "Failed to connect to a network service.  Windows could not connect to system event notification service".

However, while I was having that problem the shutdown was almost immediate.  To fix the problem went into msconfig and disabled and then enabled everything and everything is back to working - but I am back to the slow shutdown.

I think the problem is due to an issue with the wireless connection.  If I reboot with the wireless turned on the reboot takes about 5 minutes.  If I reboot with the wireless connection turned off the reboot is fast.  I also tested with the wireless turned off and I was connected to a network cable instead.  That reboot was fast.  There is definitely a problem related to the wireless connection.  Unfortunately I don't know how to solve it other than using the workaround, which is to reboot or shutdown with the wireless turned off.

Guys, I just wanted to shed some light on this an echo the above comments. It IS a wireless problem, moreso a Bluetooth problem. After 8.1 my bluetooth would not hold a connection and my PC took 3 mins to get back into windows from pressing restart.

MS tried to fix my PC (for free) for 3 hrs and could not, DELL (it's an XPS 15) didn't know either. I had emailed killer / bigfoot and had them open a support ticket due to the yellow check mark under 'bluetooth audio device' but they never got back to me.

I went to the site again to open another one and noticed they had added a BETA driver for my card, I gave it a go and now both bluetooth and the restart work.

The only thing is file transfers across the netwok are about 9 MB/s instead of an average 24 MB/s

I'll watch it for a day and if it stays the same I'll be asking Dell for a new wireless card. I'd write Killer Networks a stern email but I can't be bothered - hopefully this helps someone.

Cheers,

TC

see the solution from the following link

I've disabled the option "Turn on fast startup (recommended)" in the power settings and now the shutdown time changed form 5min to 40sec ....

Hope this helps someone ...  ;-)

10 pages in and still no response from Microsoft?  This IS their official forum isn't it?

At this point, I'm kind of getting irritated.
