Windows 7: dwm.exe not working on FIRST bootup

dwm.exe not working on FIRST bootup

Hello Community,

To begin with: english is not my mother language, so have mercy on me :)

Here is the Problem:
My dwm.exe (Desktop Window Manager, it manages the transparency and aero effect on taskbars) is not automatically started when I boot up my System.
However if I restart my computer it seems to be working just fine.
No errors, just not working when I boot my system for the first time.

Also: If I hit the power switch of my Computer the fans and LEDs set off for merely one second or a half and then turn off again.
After I press the power switch again it boots like normal.
Could this be causing the problem? for I have tried everything I have found about the topic "dwm.exe not starting"

Here are my specs:
Mainboard: ASRock 970 Pro3 R2.0
Graphicscard: Gainward GeForce GTX 780 GLH
CPU: AMD FX-6350 overclocked to 4.2GHz
(HT =1.25V
NB = 1.16V
CPU = x21.0 for 1.425V
CPU NB Core = 1.2875V)
RAM: G.Skill DIMM 8 GB DDR3-2400 @ 1800MHz, 1.6V
Power Supply: Cooler Master V850
Operating System: Windows 7 Ultimate SP1 64-Bit

Here is what I have tried so far:
- I used the system file check (sfc /scannow) command at least 5 times; never found a problem.

- I used Windows repair 2 times, after that the dwm.exe would run until after a system shutdown.

- Did a full Malwarescan using Malwarebytes; not a single virus found

- Starting the dwm.exe manually does not work, even the command "net stop uxsms" and "net start uxsms", which would deactivate and reactivate the Desktop Manager did not work

- Transparency and aero Troubleshooting could not identify the problem.

- Updating my graphicscard driver and my Windows performance index (I cann not run this when dwm.exe is deactivated. it reports that my video playback performance could not be tested)

- Went under services and checked Desktop Window Manager Session Manager; even when dmw.exe is not working it shows that it is running and set to automatically

- Ran checkdisk (chkdsk), also nothing

- Updating my UEFI

- I would rather not install my System from scratch again so this is not an option for me :/

That is pretty much everything that came into my mind regarding the things I have already done.
Help in any form would be MUCH appreciated.
If there are any Informations lacking regarding Windows Settings or Specs please state so in your comment :)

Thanks for the help in advance.

One of the optional Windows Updates from last month was a fix of DWM.exe It totally messed up my desktop and graphics so I had uninstall it. Not the exact same problem you have but maybe worth a try assuming you installed it.
