    Win10 sound lost after FastUserSwitch (FUS), unlike Win7


    I had a similar problem under dial-up on Win7 when I lost the
    connection which I made on my admin LID (logon ID), and then switched
    to the Guest LID (ERROR_FAST_USER_SWITCH). I fixed this by ensuring
    that the adapter had Owner=System (B 4, it was my admin LID). WiFi
    always worked (it was already System).

    However, under Win10, after FINALLY feeling safe to open up WiFi
    (after implementing a "system" to (hopefully) ensure I avoid the
    "Microsoft Virus" MALWARE (ie: FORCING Win10 on a working Win7
    system, and FORCING WinUpd fixes)), with Owner=System, while
    streaming an audio URL under the Guest LID (GuestX; made using a
    previous post in this forum), when I switched back to my admin LID,
    the sound was lost. When I switched back to the Guest LID, the sound
    came back on, meaning it was still playing(running).

    This loss of sound occurs for other .wavs played under my admin LID
    while logged onto the Guest LID (reverse of the above), but not for
    all. In particular, tasks under WTS (Task Scheduler) w/highest
    priviledge and as SERVICES (per TASKLIST) DO still sound under the
    admin LID even while in the Guest LID, but other tasks (in
    particular, a previous post of mine which restored sounding my
    personal .wav during logon via WTS) as CONSOLE do NOT (latter easily
    test-able since my .wav is 17sec long yet goes quiet when I do a FUS
    while it's playing/sounding(hearing) (per PROCMON)).

    Is there some setting/registry hack on Win10 to keep the CONSOLE
    audio stream sounding on the Guest LID while switching back to the
    admin LID, and vice-versa, a la under Win7? Or does this become just
    another reason (now problem# 45 for me, 8 still pending, btx Win7 and
    Win10) to stay off of Win10, or, at a minimum, don't do a FUS (for
    me, I have to run an additional CONSOLE task under the Guest LID to
    basically repeat playing the sound that would normally be heard under
    the admin LID)?

    And please don't bother responding with "install the current
    fixes"; if you can't come up w/a specific KB#, that kind of guess
    isn't a solution, and usually causes/breaks even MORE things (as I've
    already experienced, MANY TIMES, which forced me, MANY (and now LAST)
    TIMES, to restore the entire hard drive from a current backup!).
    The problem I had in Win7, and its' answer, WAS a solution.

    Thankx for your time...

    :)

  3. Recovery of Windows 10

    I have two laptops, one is updated from Vista, to Win7 and to Win10, everything was picture perfect! I did a recovery right after installing Win10, then I did a clean install and did a recovery on USB after clean install.. Not one problem. So I thought
    how simple it would be on my bigger/newer Laptop with Win8.1. Update was good, the first USB recovery was good, then I did a clean install.. wow, lost my sound, lost some MSVCP100.dll, after getting new drivers for sound, printer and the dll straightened
    out I tried to do a USB recovery and it said it couldn't do it, no errors given it just said no.

    Any ideas?

    Oh, I did have one problem with the Vista update. It seems now I have to have my video card updated to support openGL!?! How do I fix that. A favorite game that I have been playing on that laptop since Vista, and then Win7, now since installing Win10,
    I need to update my video card. How and where?
