    What are these files?


    Hi

    I have noticed (and been aware of these type of files for some time) which reside in C:\Users\My Name.
    There are 26 files which were created on 15 Nov 2015, 16,18 Dec 2015, 19,29 Jan 2016,
    23,27 Feb 2016, and 3,27 March 2016. I have checked and all but 16 Dec,19,29 Jan and
    23,27 Feb seem to coincide with Window update history.

    The types of files are:
    NTUSER.DAT{62e13463-7ee5-11e5-80c4-a4badb40df56}.TxR.0.regtrans-ms (1.0MB)
    NTUSER.DAT{62e13463-7ee5-11e5-80c4-a4badb40df56}.TxR.blf (64.0 KB)
    NTUSER.DAT{c80858a3-a3d7-11e5-bedd-408d5c50477f}.TMContainer00000000000000000002.regtrans-ms (512 KB)

    The numbers in brackets are different for each date grouping.
    What is the function of these files, are they indeed related to windows update by coincidence and could they be safely deleted?

    I am pretty sure there were only a handful of these files in Win7 and when I originally changed over to Win 10 in July 2015 (approx).

    Any advice/assistance on the above would be greatly appreciated.

    Those files are associated with the user portion of the registry. Do not attempt to delete them.

    Hello noels7 Welcome to the Ten Forums!

    LMiller7 is quite correct that you do not want to remove those "NT USER DATA" type log files seen right above the recorded registry entries which those are as well as the ntuser.ini file. That is the user account initiator file that is seen right below the 10 installers record of the user account created either during the upgrade from previous version or when seeing a clean install of Windows 10.

    If you still have the Windows.old folder on the drive you will find them for the previous version's installation in the "Windows.old\users\user account folder" as well. During any upgrade or clean install all that information is immediately backed up in case the new install is later reversed. You always want to safeguard those.files!

    It never hurts to ask in order to be on the safe side.
