'Windows Explorer Has Stopped Working' Video Files and Alt + Tab

Aye, it hit me before that a friend told me to update my CCCP to the newer version although the fact that I had entirely slipped my mind. Thanks for pointing me in the right direction folks, much appreciated!

Problem solved it seems. Flicked through loads of folders that I know would of crashed it. And can now alt+tab freely too. Strange how things work thanks everyone, you've saved my monitor from receiving my head through it lmao. :)

For me this problem was related with the DivX codec pack...


This worked for me:

Look at the Event Logs for clues about the crash.

1. Click Start, type eventvwr.msc and press [ENTER}

2. Expand "Windows Logs" category, and select "Application"

3. Identify the entry shows in Red exclamation icon, which matches the date/time at which the Windows Explorer crash occurred. (if u can't find it recreate event!)

4. Uninstall / re-install program that caused the crash - try to open the file to confirm fix.

I got this from a website (file:///C:/Program%20Files/K-Lite%20Codec%20Pack/Info/faq_windows_issues.htm#item2) when my Win Explorer was crashing whenever i opened up folders with a lot of video files.

When the thumbnail view is enabled in Windows Explorer, then it will generate thumbnails for your video files. If something goes wrong during this process, then Explorer may crash. Causes of failures can be corrupt files or buggy DirectShow filters.
Solutions:

• Update to the latest version of the codec pack. This contains a special plugin for generating video thumbnails. This plugin does not use any external codecs, and is a lot more stable than the standard thumbnail plugin of Windows.
• Disable thumbnail generation. Codec Tweak Tool -> Thumbnails -> Deselect all
• Disable thumbnail view. Open Windows Explorer and click on Organize -> Folder and Search Options -> View -> Enable Always show icons, never thumbnails.
• Identify which DirectShow filter is responsible for the crash and disable or uninstall it.
• Identify which file causes the crash and remove it. This is only useful if a single corrupt/damaged file is responsible for the crash.

DirectShow filters that are known troublemakers:

• Old versions of the DivX decoder
• CoreAVC
• Morgan Multimedia Stream Switcher
• Samsung Funbox AVI Splitter
• Samsung Funbox Video Decoder
• Voxware MetaSound
• Indeo Audio
• Nero MPEG-1/2/4 & AVC video decoder (NeVideo.ax)

Hope it helps
