It's working fine for me, try right clicking on the page and clicking refresh a few times just incase you have any corrupt js from the toolbar.

Windows 7 Pro-x64

Tried refresh and even rebooted but still get the error window when I click on Attach.

Also noticed something else. The Smile drop-down is abbreviated (fewer entries) unless in Advanced mode. Never noticed that before.

Something strange is happing. Smiles worked now. Paper clip is missing now (on Edit).

What are you guys doing? Are you messing with me?

Tried to post image of Direct Draw components but the attachment link isn't working.
The stream.sys is only a source filter and it might depends on what kind of adapters it goes through.
If you look inside the Winsat folder you can see WEI is using three media file formats: .wmv, .mpg, .mp4.

Windows 7 Ultimate x64 SP1u OEM Dell & OEM Asus
Extremly odd issue after kb3054476 appied!

well, I evaluated this Optional update as safe and likely beyond that damn free upgrade to Win10... and applied it onto 3 Win7 PCs around me...

a couple of days ago it gave me z very much odd system BSOD and Win7 fail to start on 1 desktop then. oops... first moment I guessed a lost of my system hdd but it was later found in BIOS jumped to abnormal position in boot sequence hdds' list.

anyhow problem was solved. however all troubles started from system errors:

System log error ID 7011 no response/delay of "LanmanServer", then ID 7011 no response/delay of "ShellHWDetection", then a number of Error IDs 10110 & 10111 - Kernel Drivers in User Mode.

p.s. z funniest point was when I clicked for help on one of these errors - z first popup showed inquiry for error of kernel mode drivers version 6.2.something.... not 6.1 as it's expected for Win7.

summary - not decided but maybe I'll remove this WU patch.

Detailed description of Stream.sys

For what its worth, here is a detailed description of stream.sys from IUTools:

"Stream.sys is also known as WDM CODEC Class Device Driver 2.0. It is a driver file produced by Microsoft Corporation and is part of Microsoft(R) Windows(R) Operating System. WDM is short for the Windows Driver Model (WDM) and is otherwise called the Win32 Driver Model.

"WDM is a platform that was preinstalled with Windows 98 and Windows 2000 in order to replace VxD for device drivers, because VxD was only available for older versions of Windows such as Windows 95 and Windows 3.1, as well as the Windows NT Driver Model. WDM drivers have layers of a complex hierarchy and interact with each other via I/O request packets (IRPs). The Microsoft Windows Driver Model standardized requirements and reduced the amount of code that required to be programmed. Because of WDM, driver models became consistent for the Windows 98 and Windows 2000 product lines.

"WDM drivers feature forward compatibility for a newer version of Windows. That means the driver will fail to leverage any new features included in the new version. On the whole, WDM drivers are not backward compatible with earlier versions of operating systems than Windows 98 or Windows 2000, namely, a WDM driver is not surely able to work for any older version of Windows. WDM was designed to enhance the functionality and convenience of compiling drivers for Windows. WDM was primarily created to be compatible with binary source from Windows 98 to Windows 2000.

"Stream.sys is not only related to WDM drivers which have the types of Device function drivers, Class drivers, Miniport drivers and so on, but also includes the concept and functions for a codec. A codec is program that is applied to compress or decompress a digital media file, such as a song or video. Codecs have been implemented in Windows Media Player and other programs to play and generate digital media files. The codec can make up of two parts: an encoder and a decoder capable of encoding or decoding a digital data stream or signal."

That site also lists common stream.sys errors and solutions.

If your interested it what STREAM- BASED APPLICATIONS are you can find some info here
it is an old issue of Conduit (Fall, 2002) it is published by the Department of Computer Science at Brown University that does a good job of explaining the basics because it is actually an introduction to what was then a new technology.
