How To Edit The Recently Typed URLs List In Internet Explorer

The biggest advantage of Microsoft Windows is that we can tweak it to any level through registry and make Windows work our way. And the biggest disadvantage of Microsoft Windows is the registry itself :-). Huh .. if the registry is corrupt, who will pay for it? .. because if the registry is corrupt, everything is gone.

I like tweaking Windows registry to get the desired results as we can type any command in Linux to get our desired results. Anyway, today we are going to edit the recently typed URLs history in the Internet Explorer. Let me elaborate it through the screen shot.

There are several methods to edit this URLs history. One of them is from

the registry. So let us do it from the registry first.

Editing Via Registry

Open your registry editor
Go to Start –> Run –> regedit

Find the following key:
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\TypedURLs

When you reach the key, you can see all your recently typed URLs in the right hand pane. You can double click any of them to edit them.

If you want to create a new item, right click the empty space in the right hand pane and select New –> String Value

If there are three existing keys, name the newly created key as url4. You only have to go sequentially, meaning that see the last value of the keys in the right hand pane and increment it by one and name your newly created key appropriately.

If you want to delete an existing key, just right click it and select delete.

How To Remove The ntde1ect.com and autorun.inf Files

There is a Trojan/virus (either the Win32/Pacex virus or the Win32/PSW.Agent.NDP trojan) that uses the two files ntde1ect.com and autorun.inf. Here is how you can get rid of them :

• Open Task Manager and in Processes tab end explorer.exe and wscript.exe process
• Open up File –> New Task (Run) in the Task manager
• Type cmd and hit Enter
• Type
• del /a:h /f c:\autorun.*
• Go to your Windows\System32 directory by typing cd c:\windows\system32
• Type dir /a:h /f avp*.*
• If you see any files names avpo.dll or avpo.exe or avpo.exe, use the
• Del /a:h /f avpo.exe
• Open up File –> New Task (Run) in the Task manager, Type regedit
• Navigate to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
• If there are any entries for avpo.exe, delete them.
• Do a complete search of your registry for ntdelect.com and delete any entries you find.
• To Restore Folder Options Settings, Navigate to
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL

"Registry editor had been disabled"-How to enable registry again

1- From Group Policy Editor

Go to Run –> gpedit.msc
In the left hand menu, go to User Config –> Administrative Templated –> System.

Now In the right hand pane, select “Prevent access to registry editing tools”. It will probably be not configured or enabled. If it’s enabled, disable it and if it’s not configured, first enable it, apply settings and then disable it. Most probably the settings have been applied instantly. If not, then run gpupdate in command prompt to apply the group policies.

2- From the Run Menu

I got this tweak while surfing the internet. Go to Start –> Run, copy and paste the follow in the Run box and press OK.

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f

The effects are usually instant. If not then you should see the results after restarting your computer.

Please tell us your experiences on this tweak.
