Missing or No Security Tab in Windows XP

I have an HP machine with Windows XP Media Edition,  recently I noticed, there is no security tab for files and folders. Some research showed:

By default, Windows XP come with recommended setting to enable the use of simple file sharing that hide the Security tab, leaving you with only General, Sharing, Web Sharing & Customize tabs as in the Simple File Sharing UI.

Here are the steps to hide and unhide the Security tab, just use the following step:

1. Launch Windows Explorer or My Computer.
2. Click on the Tools at the menu bar, then click on Folder Options.
3. Click on View tab.
4. In the Advanced Settings section at the bottom of the list, uncheck and unselect (clear the tick) on the “Use simple file sharing (Recommended)” check box.
5. Click OK.

Security tab is available only to Administrator or users with administrative rights. So make sure you login as one. And security can only be set in an NTFS partition. If you’re still having problem to reveal or display the Security tab on files or folder properties, you can try the following registry hack and set the value to 0 or simply delete the key:

Hive: HKEY_CURRENT_USER
Key: Software\Microsoft\windows\CurrentVersion\Policies\Explorer
Name: Nosecuritytab
Type: REG_DWORD
Value: 1
