How to delete IE addressbar history on Vista/Win7?

Question

First, here is a picture of what I see http://img713.imageshack.us/img713/4797/iedrop.png

I need an solution to clear addressbar dropdawn, but not using ClearMyTracksByProcess or IE dialogs. I need to delete only a specific URL and all his traces.

I deleted manually all traces of that URL in:

1. Users\\AppData\Local\Microsoft\Windows\Temporary Internet Files*
2. Users\\AppData\Local\Microsoft\Windows\History*
3. Users\\Recent*

also that URL can be found in:

4) Users\\AppData\Local\Microsoft\Internet Explorer\Recovery\High

Now I made an BootTime program that searches for 8 and 16 bit charsets string in all my system disc files. URL wasn't found anywhere, but after logging and starting IE, the URL is still there. I suspect this is related to 4), but can't understand how.

Finally I found solution.

HRESULT CreateCatalogManager(ISearchCatalogManager **ppSearchCatalogManager)
{
    *ppSearchCatalogManager = NULL;

    ISearchManager *pSearchManager;
    HRESULT hr = CoCreateInstance(CLSID_CSearchManager, NULL, CLSCTX_SERVER, IID_PPV_ARGS(&pSearchManager));
    if (SUCCEEDED(hr))
    {
        hr = pSearchManager->GetCatalog(L"SystemIndex", ppSearchCatalogManager);
        pSearchManager->Release();
    }
    return hr;
}

{

    ISearchCatalogManager *pCatalogManager;
    HRESULT hr = CreateCatalogManager(&pCatalogManager);

    if (SUCCEEDED(hr))
    {
        pCatalogManager->Reset();
        pCatalogManager->Release();
    }
}
