    OS: Windows 10 Pro ver.1709 build 16299.192
    Yesterday my pc almost freezed. It was hard to do anything and hard disk lights+noise were on all the time.
    I looked in Process Explorer (sysinternals) to see who uses cpu and saw SpeechRuntime.exe found in
    Is this a trojan? Micorosft tool?
    Can I remove it?
    will it help r is there a known problem with my build that will be corrected in next build?
    For the time being I neutralized SpeechRuntime.exe, kicked it from memory, and gave up speech services in
    Personalization --> Privacy
    Please help
    thank you

    Hi, it seems SpeechRuntime.exe runs if you have 'Hey Cortana' enabled.

    If that's enabled, expect a small use of CPU time (it does warn you rather obscurely about battery life when you look at that setting).

    But of course, low usage does not explain what you experienced or that your PC almost froze.

    is a valid location for that exe.

    I would also wonder what was using your disk:

    thank you for your prompt answer
    how do I disable Hey Cortana? will I have search after disabling?

    Now I see that TiWorker.exe is also running. It is found in many places under windows\winSxS\
    is it Microsoft tool? can I neutralize it?

    Hey Cortana: open Cortana (windows key + S) click the cog symbol, Settings page opens.

    TiWorker.exe - essential for updates - trusted installer. It can sometimes use a lot of CPU time if something's amiss for a few people.
    Is it using much CPU time?
    You can easily research it- just search for TiWorker.exe

    You shouldn't really be looking in WinSxS- that's essentially a storage repository used for reference when runing SFC /SCANNOW e.g.

    Please post a screenshot of your Update History.

    When the update is complete- assuming it does complete- run
    chkdsk C: /scan
    and advise the result
    from an elevated (admin) command prompt
