Windows 7: No sound from media files after 'IObit' system improvement software

Thanks, this will take a while - there are a lot of changes. Providing as much information as possible is always good - thanks for the notation on Windows Update.

I'll try to compare the two files to see where a change might be affecting your machine. Bear in mind that I'm helping other members and also playing with Win10.

I'll post my findings when I have any. Do NOT apply the rescue just yet.

Another member might drop in and give you some other things to try - who knows, they might provide a solution while I'm reading the stuff you posted.

I'll catch up on posts the next time I get back to your thread.

Lots of keys, nothing jumped out that would cause the issue - I did not look up all of the GUI strings though.

Turn on System Protection
- right click Computer,
select System Protection,
select the C: drive and
press the [Configure] button
turn on system protection and
-set Disk space usage to about 10% of your disk.
press [Ok]
press the [Create] button

Then go ahead and use the iobit utility to restore the rescue registry.

Restart your machine
-> Does sound work?

Unfortunately no. No improvement or any change for that matter.

Sadly, it may be as I suspected in the beginning.

I have found once IObit has been chewing on you system a Clean Install is the only answer.

If one tries to fix problems as they arise you will be forever.

x64 (6.3.9600) Win8.1 Pro & soon dual boot x64 (6.1.7601) Win7_SP1 HomePrem steps
  • Manually run Windows Update
    Select all items offered, including any in the optional section
    download an install the updates

  • Restart the machine in case any operations are pending

  • Follow the instructions in:
    Windows Update Posting Instructions
    -> Ignore the title and references to Windows Update, these utilities are also useful for other issues.

    Read Step 4 carefully, many people misunderstand that they need to attach the entire CBS folder in a compressed folder (zip). If it's too large for the forum, just attach the entire CBS.log

    Skip Step 5 - that's a generic step more for people who jump in another thread and start posting the issue on their machine. It gets confusing - step 5 asks them to start a thread of their own.

    This is your thread - you want to post the output here - no need to start a new one.
