Hi, recently whenever i have checked the security tab of my files, I see the above thing: Account Unknown (S-1-5-21-130066488-785734366-1129733132-1000), should i worry about this?? a hacker or something?? how can i delete this, it has "special permission".

I give up, what is it - and what's a "security ownership panel?"

Yeah it's tagged all over .mp3 files, windows 10 can not address data permissions or account, and it's messing with ratings, then players play anything but random, so definitely made or exploited to drive crazy. the rating media player, is unable to affect
rating portrayed by explorer.

dual bios here machine fount on street corea made, say this if inputs audio are limited by windows10 revert to win7...Gygabyte responce. So defenetly institutional intrusion on media usage for me. Excellent sound from system, random play and rating metadata
is a fail.

specifically how remove from data this account info, automated from all files, and disable code? Like my Dolby Panasonic decoder for sound amplifyer married well with corean Realtek HD audio, but was messed up when ATI video card code came along NVIDIA High
definition Audio messed up, this is all AS CD white book copy protection identifying machines... Crypling indiscriminately and or incriminating automatically.

instructions requested for removal pleas it's bugged out.

another repressive technology on intelligence.

 

Are these files that you have copied from another computer or even a previous install of Windows on the same computer? It might be pointing to a user that was on the system where the file came from that is not on your computer.

 

I have never reinstall any windows since my purchase, and there were no such anomaly before.......

 

Hello Keith, *Smile

In addition, an unknown SID in permissions could also be from an account that had access to the file and has since either been deleted or not currently available.

 

thanks!! so i guess i can just ignore them??

 

@keithktam, looking through the registry of my current machine I find entries under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\DataStore that may help explain your unknown account.

I have four accounts on my machine and there are four corresponding keys here, \S-1-5-21-nnnnnnnnnn-nnnnnnnnnn-nnnnnnnnnn-1000 to ...-1003. Each one has a sub-key ...\0 containing the string szName. These holds the values "Computer\User" where "Computer" is my machine's name and "User" is the name of each of my user accounts. I have never deleted an account on this machine, but on another machine where I have created new accounts and deleted old ones those keys now start at ...-1003.

The '-nnnnnnnnnn-nnnnnnnnnn-nnnnnnnnnn-' part of the SID is unique to each machine, if this part of your 'unknown account' is the same as the current ones then it was probably a local account on your machine. From the '-1000' part we can deduce it was the first account set up when Windows was installed. The most likely explanation is that since Windows was first installed new account(s) have been created then the initial account deleted. If this is indeed the case then you can safely ignore it - that account no longer exists.

 

Sometimes when you install windows it creates a user defaultuser0 with the -1000 suffix. It needn't necessarily be a user you personally created.

Like you say you can ignore it.

 

Glad we could help. *Smile
