Removing a "hidden" user and user files

Thanks for your patience. I was able with "Net User" to remove the left over user. It no longer appears when I invoke Net User.

Now for the user's folder which remains behind. After performing the series of steps that you suggested, I attempted to delete this folder. The result again was an error message about permission


"Administrators" appears on the list in the list of advanced security.

 

Delete "hidden network"

Hi,

Deleting or Blocking available networks can only be done using Command Prompt. Follow the steps below:

• Open Command Prompt.
• Type netsh wlan add filter permission=block ssid="WLAN name"
  networtype=infrastructure (Replace WLAN name with "hidden network" or the name of the wireless network you want to block) and press
  Enter.
  
• Close Command Prompt.

To remove/delete the network from the block list. Replace "add" with "delete" on the command in step two.

Looking forward to your response.

 

Hidden folders

I installed `Kane and Lynch` on my PC twice in Program Files(x86) folder but I can`t find them (2 folders with game). But free space on my HDD is lower. So there`re those folders on my hdd. I use option `unhide` hidden folders but still can`t find them. Any suggestions? How can i delete those hidden folders?

When I run istallation for this game I can see those folders in Program Files(x86) folde.

I`m using Win 7 Ultimate 64 bit.
