I am using Windows 7 64-bit, and have a tendency to postpone windows updates. While I was sleeping last night, my computer held a coup, and installed the latest update, then rebooted. When I tried to play an .avi this morning, I found that there were several clicks at the beginning of the file, then the video would play in slow-motion, and the sound was extremely choppy. (Every word, or syllable would repeat 2-4 times.) I watch about half of this video last night, and it played fine.

I tried downgrading VLC, then upgrading back to 2.0.2 and deleting preferences. (Neither worked.) I also tried playing the file in BS Player, to no avail. Finally, I tried playing files that were stored on a different drive, yet all my videos played in a similar fashion. My music is fine though, as is streaming video. I've already scanned my computer with CCleaner, Glary Utilities, and Tune Up Utilities 2012, defragmented my C: drive, and restored my system to before the update was installed. I am now completely out of ideas, and have decided to come to you.

Before "trying stuff", do a "system backup"(An "image" of your entire machine.), to bootable external storage(DVD, flash drive, etc.). Then if you REALLY screw-it-up, you can restore it at least back to the way it was......

You could try to un-install the Windows Updates you just got(At least those that are un-installable.), to see if it helps? Should be available on your WUD history list. If no help, re-install them. If it DOES help - re-install them one-at-a-time, then do a re-boot and a "video check", before installing the next one, etc., to try to find the 'problem causing' update. Going back to a "system restore point" may help? Don't know, never tried it(I'd back-it-up, first!).

Other possibility --- MY 'streaming' videos were "suddenly" bad, recently. Tried lots of stuff - no luck. Then I finally un-installed Adobe Flash Player, then re-installed the latest AFP. All is fine, since... In other words - try updating(New Codec or video drivers?), uninstalling/reinstalling ALL the software that "works with" your videos. One place you should look is AT Windows Update, itself! If you do "automatic" WUD's, you may never see WUD trying to tell you there is a new "hardware update", or some "other" update, that you need(Though everyone may not.). WUD is pretty good at telling me when my video drivers, for instance, are out-dated - but I'm not sure that happens if you have WUD set to "auto-update only the critical" stuff(I've never tried it.)...

If "it" happens "all-at-once", try to figure out and remove/correct what the last thing you did/changed/installed, etc., was......

If "it" happens "over time"(Days, a couple of weeks?), you better be doing regular image backups(And keeping a stock of them - like once a week for the last four weeks!). "Over time" problems are generally software "going bad", or hardware "going bad". If you wait until it REALLY breaks, you may be "done" with that hard drive and everything on it.

Have Fun!(And I mean that - if it's not fun, wait until you feel more like playing IT. Don't work on the machine when you're mad at it or tired.).....

Thanks for the advice Teddy. I was getting worried as I can usually at least pinpoint what the issue is that's causing problems, but as I mentioned above, I was completely out of ideas. Fortunately Windows released another update tonight that fixed the issue.
