Hey guys,
I recently upgraded from Windows 7 to windows 8.1, and instead of getting faster, the boot starts to take more and more time. It takes about 1min+ to get to desktop now. Any reason why?
Also, in windows 8.1,.while gaming (graphic intense games only, such as Battlefield 4), the alt+tab is very slow. It first shows a black screen for about 5 seconds then switches tab. Is there a fix for this? Thanks!

Concerned system specs:
CPU: I7-4770k
Boot drive: Adata SX900 128GB
Ram: corsair vengeance black 2x4 GB
GPU (maybe) :. GTX 760
PSU: corsair cx500

EDIT: I've limited the startup processes to only the essentials. I have Bitdefender Total Security.

There are a few things to try in order to improve performance.
You don't really need a 3rd party AV, Security Essentials is included in Windows Defender, and more often than not I'm finding machines with extra AV running alongside Security Essentials are slowing everything down.
Best update your drivers, esp. GPU.

Run diagnostics to check out your OS,

First try System File Checker
Winkey plus 'X'
Choose Command Prompt (Admin)
Type sfc /scannow then Enter

It finds and fixes errors in Windows, but doesn't always report them. Run it and see if the fault disappears after...

If corrupt files are found that can’t be fixed, try

Dism /Online /Cleanup-Image /RestoreHealth (Observe spaces before /)

Re-run SFC

To view CBS Log

findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >sfcdetails.txt

Search C drive for sfcdetails.txt or navigate to C:\Windows\System32 and scroll down
Edit
Actually there is no substitute for a 'Clean Install' and a fresh start, so if all else fails this can be achieved with an Upgrade disk...
