Delete Browsing History: Windows displays history anyway

Delete Browsing History: Windows displays history anyway

Is does not matter to which websites you are interested. To remove traces of traces in the form of cache, cookies and history, Firefox, Chrome, Opera, or Internet Explorer offer their own menus. As a rule, you can reach them by clicking on a specific key sequence or key combination - specifically Ctrl-Shift-Delete. The keyboard shortcut can fail if a mouse click is made in a web page input field. If you have completed the elimination, local spying actions should be excluded. But error: Windows keeps a site list invisible!

DNS content survive Chronicle cleanup
The misleader listens to the name DNS cache and actually acts for the benefit of the user. Since web page calls are made invisible by controlling their IP addresses, the PC asks when visiting Google for its IP. The demand is directed to your own DNS provider. If you do not have a specific DNS server in the router menu or in Windows, you usually use the Internet provider (ISP, I nternet S ervice P rovider) as a DNS service provider. So he is looking for the IP address of Google and is responsible for making contact based on the looked up IP number. Now, asking for IPs takes some time. It is faster to take IP information directly from the PC. This is the idea of ​​a cache: Windows has a DNS cache. The system saves website addresses along with the URL-related IPs. A cache also have processors or Windows since Vista in the form of SuperFetch.


Show DNS cache: How to get to the history
Even if you remove all animated surfing ballast in the browsers mentioned at the beginning, the DNS-information stored temporarily between the operating system remains. You can open up the command line with Windows key and R and the command cmd with the help of an experienced snoop or hacker from a distance that has malicious code. Using the command ipconfig / displaydns , you can see the most secret content. Just try it: the command tells you what others might sniff.

Here's how: Delete DNS cache
Remove the contents in the DNS cache! Either immediately after reading out the displaydns parameter or from the beginning. If necessary, start the command line first, using Windows-R and cmd, for example. Now type ipconfig / flushdns in the command line. Less quickly, but even more simply by Windows reboot or shut down the computer. Cleaning when shutting down will work even if the Windows 8/10 startup is enabled. Only domain names, not the full web addresses, appear in the command line; There are no references, for example, to this COMPUTERBILD article. That you have visited computerbild.de can be seen.

Further protection
Empty your DNS cache regularly if you attach great importance to security, for example, by shutting down the operating system. The DNS cache acts as a turbo for web page calls, but could cause problems: Rarely change IP addresses of web sites, so those in the Windows cache are no longer up-to-date. If you do not want the DNS turbo completely, disable it: Press Windows-R, type services.msc for service management, double-click the DNS client entry, and set the startup type to Disabled and select You exit . Save the startup type using Transfer > OK .

Consider the following: If you switch off the cache, you may be slightly slower. On the other hand, do not disturb any outdated IP information. And if you want to get a picture of your surfing habits via ipconfig / flushdns on the command line, you will see nothing useful. On the other hand, a research source for PC security is missing: When the software is contacted with the server of its originator, the DNS analysis often indicates this. Servers that you have not contacted are listed in the evaluation; Some of them also show up in advertising, which could irritate you and do not pose any danger. However, a DNA analysis is nevertheless a good indication for a targeted complete virus scan. It is to weigh up whether one wants to do without the invisible background functionality or not.
