DropBox leaks suspended processes when it cannot poke through your HTTP Proxy

Posted by jpluimers on 2013/03/08

On Windows, when you have a HTTP Proxy Server and DropBox cannot poke through it, it pops up a window asking if you want to change the “Connection Settings”.

When you have a busy proxy that denies access when busy, but allows when not busy, the window disappears and DropBox continues.

So far so good you think?

Not! DropBox creates suspended process instances of itself when showing or removing the window.

And when DropBox exits, it doesn’t cleanup those suspended processes: you have to do that yourself.

They take up a couple of hundred kilobyte each.

You can use Taskkill. to clean them up like this:

C:\users\jeroenp>taskkill /F /IM Dropbox.exe

Which gave this result on my machine after about 15 minutes:

SUCCESS: The process "Dropbox.exe" with PID 22632 has been terminated.
SUCCESS: The process "Dropbox.exe" with PID 23680 has been terminated.
SUCCESS: The process "Dropbox.exe" with PID 21240 has been terminated.
SUCCESS: The process "Dropbox.exe" with PID 22312 has been terminated.
SUCCESS: The process "Dropbox.exe" with PID 22568 has been terminated.
SUCCESS: The process "Dropbox.exe" with PID 23116 has been terminated.
SUCCESS: The process "Dropbox.exe" with PID 23288 has been terminated.
SUCCESS: The process "Dropbox.exe" with PID 5328 has been terminated.
SUCCESS: The process "Dropbox.exe" with PID 16784 has been terminated.
SUCCESS: The process "Dropbox.exe" with PID 17248 has been terminated.
SUCCESS: The process "Dropbox.exe" with PID 15056 has been terminated.
SUCCESS: The process "Dropbox.exe" with PID 21508 has been terminated.
SUCCESS: The process "Dropbox.exe" with PID 16276 has been terminated.

I’ve seen this behaviour on Windows 7.

Posted by jpluimers on 2013/02/25

Finally I found a good list of error codes that you might encounter when doing Windows/Microsoft Updates.

The page is for Windows XP SP3, but the error codes occur in many other update situations as well.

Error code that appears in the WindowsUpdate.log file Error Code description (as it may appear in the Svcpack.log file) Knowledge Base article that describes potential resolutions
0x8007F0F4 STATUS_PREREQUISITE_FAILED 949388
0x80246007 SUS_E_DM_NOTDOWNLOADED 949386
0x8007F003 STATUS_NOT_ENOUGH_SPACE 949385
0x80070005 ERROR_ACCESS_DENIED 949377
0x800706BE RPC_S_CALL_FAILED 950718
0x8007F02B STATUS_NOT_ENOUGH_WITH_UNINST 949375
0x87FF0004 Error_Too_Many_Open_Files 950718
0x8007054F Error_Internal_Error 949384
0x8007001F ERROR_GEN_FAILURE 950718
0x8007F070 STATUS_SETUP_ERROR 950718
0x8007F205 STR_UPDATE_ALREADY_RUNNING 949381

0x80070001 ERROR_INVALID_FUNCTION 950718
0x80070002 ERROR_FILE_NOT_FOUND 950718

0x87FF054F n/a 950718
0x87FF36B7 n/a 950718

Oh and this didn’t solve my problem:

  • REGSVR32 WUAPI.DLL
  • REGSVR32 WUAUENG1.DLL
  • REGSVR32 ATL.DLL
  • REGSVR32 WUPS2.DLL
  • REGSVR32 WUCLTUI.DLL
  • REGSVR32 WUPS.DLL
  • REGSVR32 WUWEB.DLL
  • REGSVR32 WUAUENG.DLL

The Missing Windows 8 Instructional Video (awesome 25 minutes, via: Scott Hanselman – G+)

Posted by jpluimers on 2013/02/21

A couple of weeks ago, Scott Hanselman posted a great Windows 8 instructional video.

It contains all the stuff that geeks like me will find out themselves over time, but in a well paced and complete manner:

… to give new users to Windows 8 a near-complete understanding of the major features including the Start Screen, Hot Corners, Full Screen Apps, Desktop Apps, The Store, Browsing, Doing Social Stuff, using the Mouse effectively and exploiting keyboard Shortcuts.

It also shows what a power user like Scott uses besides the standard Microsoft Windows/Office combo.

Oh: and it includes the “Windows-X” shortcut (:
(no: not the mobility center any more)

Recommended watch!

Google Chrome funny error message: trueAre you sure you want to leave this page?

Posted by jpluimers on 2013/02/21

Got a nice error message from Google Chrome today and wonder what the “true” means (:

true

The text is this:

[Confirm Navigation]

true

Are you sure you want to leave this page?

[Leave this Page]    [Stay on this page]

You can use Ctrl-C to copy, then you get the text below:

trueAre you sure you want to leave this page

That means it is not a standard Windows MessageBox, as pressing Ctrl-C there would copy the title and buttons as well.
