    sfc /scannow Hey! Windows Resource Protection found corrupt files and
    successfully repaired them.
    For online repairs, details are included in the CBS log file located at
    windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log.

    cbs.log was 6 megabytes, didn't understand it.


    Might there be a log entry somewhere of what went wrong?

    Last December, Amazon had the same refurbished computer with win10 or
    win11. Does that imply that win11 was an upgrade and not a fresh
    install, and could that be a problem?

    Windows 11 Freezes for no apparent reason.

    Dell Latitude 5510, about 4 years old, bought refurbished from Amazon
    last winter, 32gigs ram.

    Five times now over the last 3 months. Not doing anything special. This >>> time I was clickilng on a tab in Firefox. Don't remember previous
    times.

    Cursor shows but will not move, external mouse does nothing, external
    keyboard does nothing. Uncover the laptop's keyboard but it does
    nothing, mousepad does nothing, only key that works is power key. Hhave >>> to hold down for 15 seconds and restart.

    Thought maybe it was overheating, becasue I covered the keyboard to keep >>> it clean. Uncovered it for 15 minutes, no change,

    Using far fewer resources than in pervious win10 computer when I often
    went up to 100% CPU and 96% memory. Now I have 32Gigs instead of 8 and
    after restarting all the same programs, I was only using 35% of memory
    and about 9% of cpu.

    Even thought it's 4 years old, I'm constantly getting Dell updates,
    including 10 updates to the BIOS during the summer. I thought BIOS
    software was rarely updated and not at all after a year or two.

    (Looked brand new when I got it except was supposed to be black and it's >>> silver with a wood-grain surface texture which immediately gets dirty
    and won't just wipe off, although it was clean when when I got it.)

    Go to Settings and enter "Relia" to see an entry for Reliability Monitor.

    It shows major events and displays their Event Viewer information (eventvwr.msc).

    Lots of data there. Didn't see anything special.

    Just be aware, there are freezes that generate no log whatsoever. After

    That's discouraging. But it's only happened 4 times and not in the
    last 8 days. That's encouraging.

    I'll get back to you if I learn more.

    a power cycle, the Reliability Monitor will level an accusation of a
    "dirty shutdown", as an interpretation of finding a dirty shutdown sideeffects.
    But that's not the freeze log. If you're frozen, all I/O can easily stop
    on a dime. All it takes is being frozen in a kernel call.

    I had a kind of freeze, that resulted in a BSOD, and the claimed
    event there was a "DPC watchdog timeout". That's where Delay Procedure Calls >associated with Interrupt servicing, are piling up and not getting serviced. >But in my example there, the freeze became "unfrozen" in time, to blow
    the BSOD instead, and the BSOD got logged. The BSOD was just a side effect
    of a freeze, where the system (eventually) got a chance to report "something". >Again, not getting to report the root cause, just report a late side effect of it.

    I have seen some strange things in Windows like that, where there are
    no comparable incidents on the Linux side. This doesn't mean anything >particularly, except that whatever the root cause is, is not

    Indeed. I just checked my Reliability Monitor.
    Looks like my PC was partying on Thursday, and the
    party stopped when a definition update for Windows Defender
    came in.

    I haven't seen anything like that before.

    Another, when it's not(hardware).

    A failure to update definitions, not even worthy of investigation.
    - it updated successfully, and automatically one minute later

    Working on all your suggestions, but busy with some other problems also.
    I'll get back to you all if I learn something.
