Windows 8.1 Pro x64 UEFI very slow boot and shutdown

Youhou!! Thanks a lot!! 

Same problem than you with the same computer and after trying thousand of solutions that i found in many forum, finally this one works!!!

I recently bought an Asus N550JV, and I was also experiencing slow shutdown and reboot times after upgrading to Windows 8.1.

I fixed the problem by uninstalling "Qualcomm Atheros Bluetooth Suite (64)" and reinstalling the latest version "8.0.1.305", which I downloaded from Asus' website.

Clearly there was a problem with the old driver or software running on Windows 8.1, causing the system to hang while it closed down.

I also have new HP laptop and upgraded to 8.1 from store but it takes too much time to start up and shutdown even I don't have installed more apps. This is very irritating and disappointing please solve this problem Microsoft.

I am using Pro and it is very slow compared to just Windows 8.  I just build this system a few months ago and I was enjoying it being bug free.  I put in a i7 4770k processor, Gigabyte ud5h z87 motherboard, 16 gigs of RAM, 240 Gig SSD, and a GeForce GTX 670 graphics card*;* it booted in 15 secs.  Since using the 8.1 update, my system takes +4 minutes to boot and about 5 minutes to shutdown.  Arrrg! I have updated all the drivers, I have re-flashed the bios, I tried a new user account and nothing works!! On top of this I have been trying to figure out why I have a memory leak!!! If I didn't have to reconfigure all my photography software I would rebuild the hard drive again and just stay with Windows 8.  Luckily, I only set one computer to 8.1 the others will stay at 8.0. 

Hey Microsoft!!! Fix this!! Or else I am switching my whole company to Apple the next time we need to upgrade!

I have had windows 8.1 64bit Pro installed since the day it was officially released... and yes prior to that windows 8 was booting up in about 5 seconds on my SSD, but like everyone else 8.1 was taking about 30 seconds to boot...

I know everyone has been saying it was the it was because Microsoft removed the Window Experience Index... but I have tried all the recommended tweaks to fix boot time... none of them worked...

Like many here, I have had the slow boot time, I even post on the subject 3 months ago, none of the advice helped me though... even my own advice at the time...

However, I am back to a fast boot & shut down time with 8.1... the only thing I can see that I did different to every one here is, not installing drivers...

about 3-4 weeks ago, I re-install windows 8, but did not install any drivers... just did a lot of windows updates, and there was a lot... and a few days after it had settled down... I upgraded to windows 8.1 (although I was dreading the slow boot times)...

Although I installed software (games & office), I never installed my hardware drivers, I just let windows install what it wanted... windows even installed the latest Nvidia drivers for me...

For the past few months, I have seen so many post about incompatible drivers that people have installed... but that's the difference.... every one with slow boot/shut down times, reinstalled their drivers after reinstalling windows...

Maybe the reason that's Microsoft have not issued a fix, is because they can't fix the users.... Tablets & Smartphones don't have problems, because users don't install drivers...

Basically, there is no possible fix...

I do have to point out that the other 2 computers I upgraded are fine... A Toshiba Satellite and a homebrew Sandybridge with a Gigabyte MB. And that if I can somehow get into safemode (why doesn't troubleshooting recognize my wireless keyboard!!) the computer in question boots as it should.

Most likely in Safe mode the wireless drivers are not loaded.
