    Why is RFC 1323 Timestamps disabled by default?


    Despite some literature reference, RFC 1323, and therefore both Window Scaling and TCP timestamps are disabled by default in Windows 10 at least.


    It would be interesting for our research team to understand why, as it limits the bandwidth of TCP streams, and other important high-speed features.

    :)

    How to disable Last Accessed date ( timestamp ) on FAT32 file system?

    Scope of that article is how to *enable* the last accessed timestamp as it's disabled by default on NTFS drives.

    Was it any special steps you were thinking about? I've already tried the fsutil command (see above); without rebooting though.

    Lost default photo viewer after profile rebuild


    Thanks Brink. I've tried those steps before i started searching Google. After the profile rebuild i don't have the Photo app listed to choose to make it default in either the system settings for default apps or the Open With option.

    I can't even find it doing a search. Seems to have been removed somehow with the profile rebuild, which doesn't make sense.

    Might be helpful to list what i've done Why is RFC 1323 Timestamps disabled by default? :) I've done the open with check, the choose default program in the system menu, tried that in device manager default programs also. I've checked the programs and features Turn windows features on/off and it's not listed there (never thought it was but that was a suggestion), searched the MS Store, it's not listed there either.

    I don't like playing in the registry unless i have defined steps and haven't found anything for this yet, just the Win7 version like in my OP.
