Windows 7 laptop takes 20-25 minutes to shut down, even from Safe Mode

Now I know that you are not going to believe me, but keep the faith.

WIN | type MSCONFIG | ENTER | STARTUP tab |
Uncheck ALL

REBOOT!

You have just told Win 7 to not run unchecked programs at start up time.

You have not disabled the programs. They will be run when needed.

WIN = key with the Microsoft logo on top

=====================================

Just do it and be amazed at the performance improvement.
After your system is working correctly, then you can go back and check anything that you, right now, think is absolutely essential to run at startup time.

Now here is another one you won't believe, but one again just keep the faith.

CCLEANER | TOOLS icon | STARTUP tab | SCHEDULED TASKS tab |
Use DISABLE button to disable ALL

Close CCleaner.


REBOOT!

You have not disabled any programs. You have disabled the scheduled running.
Later, after your system is running smoothly, you may reenable desired programs.

Duckbill,

Oh my god! I've just looked at your install list. What a chamber of horrows!

Now I'm going to list some programs to delete as a start.

You could do me afavor by uninstalling everything not dear to your heart.

You would be doing yourself a real big favor by uninstalling everything yo don't need.

Your system will run better, faster, fewer bsods.

Now let's start with:

UNINSTALL

Script:

Bonjour    Apple Inc.    
Process Hacker 2.27 (r4957)
Secunia PSI (2.0.0.3003)
Spybot - Search & Destroy    
SUPERAntiSpyware    
µTorrent 


REBOOT

I included Secunia because you version is old. Secunia is a great program. You will want to get the latest version.

I know. Once again, you saying no way I'l do that. Once again, Keep the faith.

Now here comes a sermon:

REMOVAL OF P2P PROGRAMS

There are signs of one or more P2P (Peer to Peer) File Sharing Programs on your computer.

As long as you are using any form of P2P networking to download files, you can anticipate malware infestations.

References citing the risk of using P2P programs:
How cyber criminals infect victims via P2P with pirated software on Vimeo
Malware: Help prevent the Infection
Perils of P2P File Sharing
How to Prevent the Online Invasion of Spyware and Adware
The Hidden Security Risks of P2P Traffic


I strongly recommend that you uninstall:
µTorrent
BitTorrent
Vuze

OK, I disabled all that startup stuff and scheduled tasks, and uninstalled the stuff you recommended, and updated Secunia. Unfortunately my shutdown is still at 23 minutes from pressing the button to powering off.

Edit: I mean my shutdown after doing all that and then rebooting, obviously.

are you connected to a home network?

Please post an updated set of CCleaner files.
thanks,
karl

can you run the computer standalone, no router, no wifi, no internet?

Please do and let me know what the startup & shutdown times are.
thanks,
karl

Please run an MGADiag report - it may give us some clues....

We need to see a full copy of the report produced by the MGADiag tool
(download and save to desktop - http://go.microsoft.com/fwlink/?linkid=52012 )
Once saved, run the tool.
Click on the Continue button, which will produce the report.
To copy the report to your response, click on the Copy button in the tool (ignore any error messages at this point), and then paste (using either r-click/Paste, or Ctrl+V ) into your response.
