If you want that nobody can understand, what sites you with your browser have visited, it seems to suffice to delete entries such as history or cache. Unfortunately, this is a false sense of security. You need to clear the DNS cache.

to clear the DNS cache and the stored list of domain names

  1. invoke the Run dialog with [Win +R] .
  2. give cmd a and press the Enter key.
  3. now opens up a window for entering command line commands.
  4. you type here ipconfig / flushdns an and press the [Return] -button.

    This clears the cache for DNS queries.

  5. so that the cache is empty and all stored host names are gone.

Note for Vista users: you must start the command line as an administrator. Otherwise, Windows denied the deletion. Windows 7/8/10 it works, however, with a simple command line.

why the DNS cache contains sensitive data

DNS is the service which determines the underlying IP from the input host name such as “tippscout.de”. To do this, of your local DNS server is questioned each.

so now retries of requests result in no new access to this server, Windows stores operating system-level results in the DNS cache between.

This means that here, although not complete Web addresses, but all server names are found, that you have visited recently. That alone can be embarrassing enough already.

incidentally, helps private mode , here neither have the many browsers, because they all use Windows for DNS queries.

so you see, despite deleted browsing history, what sites have been visited to itself

to see what information of the cach for saved on your PC, proceed as follows:

    with [Win +R] ,

  1. call on the Run dialog.
  2. give cmd a and press the Enter key. The command ,

are here many domain names find, that you have visited recently. While not the complete address is here to recover, but some domain names are so critical enough.

to store the list of domain names in a text file

you want to more closely examine the stack, the command line is bad.

to do this, it is better if you speichernt the information in a text file. [

to enter in the command line window a: ipconfig / displaydns > % homepath%Desktopcache.txt

thus was created the “cache.txt” file, which you now by double-clicking in the text editor display can.
