installed the latest updates of windows 7... now the computer does not recognize my video files avi... says "format not supported".

I have installed the latest updates (02/27/10) and when I open sony vegas to edit some files avi... they were offline... when I tried to read with windows media player it says format not supported... before when I played these files, they would not have to synchronize audio... it never happened with my other computer with Vista... system restore solved the problem of format not supported... but so far has caused this problem? and what about the problems of synchronization? the files seem to sync when played with the hp program...


Hi derlonewolf,
Because you performed a System Restore you would not be able to determine which update problem from occurring. You will have to wait for the update to your computer to determine the update that caused the problem. The update does not necessarily cause the problem to occur again. However, you can view the history of updates to updating history.
1. open the control panel (all items view), and click the Windows Update icon.
2. click on the link to view update history.
3. to view the details of a single Windows Update-
(A) select and right-click on a Windows Update list, and then click details.
(B) click on close when finished.
As far as the question of timing is concerened, you can scan SFC on your computer and check if the problem persists.

Steps to perform a scan SFC:
1. Click Start, click principally made programs, accessories, right-click Guest, and then click Run as administrator. If you are prompted for an administrator password or a confirmation, type the password, or click on allow
2. type the following command and press ENTER:
[The command sfc /scannow. analysis of all protected system files and replaces incorrect versions with appropriate Microsoft versions.]
A message appears indicating that "the system scan will start. Be patient, because the analysis may take some time
3. If all the files require that a SFC replace will replace them. You may be asked to insert your Win7 DVD for this process to continue
4. If all goes although you should, after the analysis, see the following message "Windows resource protection not found any breach of integrity.
5. once the scan is finished, close the command prompt window, restart the computer and check.
Check the link below for further guidance on scan SFC - mentioned
You can also make manual updates instead of automatic updates and then see what are updates will be installed on the computer.
