Folder option problem

When I choose tools -> folder options -> view, and check "Show hidden files and folders" radio box, and open the same window, again it shows that "Show hidden files and folders" radio box is unchecked. I could not check it anyway. The same problem occurs when I try XP in Safe Mode with the Administrator account. What can be the problem?

This can be caused by a virus ( W32 ), Malware, or an error in your registry.For the first two possibilities, you need to install a proper Antivirus / Anti-Spyware program and run a scan.

You can also try the following:Open notepad, and type the following text (Please make sure the spelling is correct ):
WindowsRegistryEditorVersion5.00[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden]"Text"="@shell32.dll,-30499""Type"="group""Bitmap"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,\00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,53,00,\48,00,45,00,4c,00,4c,00,33,00,32,00,2e,00,64,00,6c,00,6c,00,2c,00,34,00,00,\00"HelpID"="shell.hlp#51131"[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\NOHIDDEN]"RegPath"="Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced""Text"="@shell32.dll,-30501""Type"="radio""CheckedValue"=dword:00000002"ValueName"="Hidden""DefaultValue"=dword:00000002"HKeyRoot"=dword:80000001"HelpID"="shell.hlp#51104"[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL]"RegPath"="Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced""Text"="@shell32.dll,-30500""Type"="radio""CheckedValue"=dword:00000001"ValueName"="Hidden""DefaultValue"=dword:00000002"HKeyRoot"=dword:80000001"HelpID"="shell.hlp#51105"
Save the file "RegistryFix.reg", and close notepad. Double click on the file. The information should be modified / added in your registry.
You can also try the following operation:
Go to the "Start" Menu, select "Run", and then type "sfc /scannow".

Disable access to System properties

Using the System properties applet in Control Panel, a user can change the name and/or domain membership of the computer, create hardware profiles, manage devices, and specify performance parameters such as memory usage, virtual memory settings, and visual effects. This registry edit allows you to disable access to System properties, both from Control Panel and My Computer/Computer Management.
1. In your registry editor, logged on as the user for whom you want to restrict access, navigate to: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer.
2. Right-click in an empty portion of the right details pane and select New DWORD Value.
3. Rename the new value to NoPropertiesMyComputer.
4. Double-click the new value and enter 1 in the Data Value field to hide the properties. If you want to make the properties accessible later, change the value to 0.
5. Restart the computer to make the change take effect.

Don’t show the last logon name...

If you’ve elected to use the standard logon dialog box instead of the Welcome screen, or if the XP computer is joined to a domain, XP tries to be helpful by displaying the account name of the last user who logged onto the computer; you only have to type in the password. However, this is a security issue because it gives a hacker half of the information needed to log on. Why make it easier? Of course, you should already have renamed the administrator account and disabled the guest account so a hacker won’t have those account names to use. The next step is to disable the display of the last logged-on user. Here’s how:
1. In your registry editor, navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System.
2. In an empty portion of the right details pane, right-click and select New DWORD Value.
3. Rename the new value dontdisplaylastusername.
4. Double-click the new value and enter 1 in the Value Data field.
