How to delete unknown account in win8 (s-1-5-21-2000478354-1390067357-725345543-1003)

                                                                                                                                                                                         Today, I suddenly found that the game compressed files copied from other places could not be decompressed, and the game files were previously placed in this directory. In the past, the local area network played games and could not be used as a host, and could not download the RPG maps played by the local area network. I have noticed this unknown account (s-1-5-21-2000478354-1390067357-725345543-1003), I think it is a problem, but it has not been solved. It is a bit angry today, I must delete this broken. Unknown account! ! I started searching online. . Said to be a problem left over from the previous system account, manage him, can delete it and try the method one: first select a partition, then select the right click — & mdash; security & mdash; & mdash; select the advanced button & mdash; & mdash; select the owner Label —— select Edit —— then select the administrators group (administrators) and hit the checkbox below, click Apply. After the above steps, the owner of all files becomes an administrator. Step 2: Select the partition just now, then select the right click ——security—— select the advanced button —— select the permissions tab, then click the change permission button below, hit the bottom hook and click Apply ! But there is no owner option in win8! ! Let me feel so good! I only found my own way. I didn't expect that the unknown account disappeared: right click —— attribute ——security——edit ——select account——complete control, modify, Read and execute the checkmark of & remove the —— application —— to make sure that the account should disappear and all other functions are normal! ! ! !
