You surely dislike when you conduct a search on Google and the search engine returns a number of good results, but when you try to open the ones that looks the most interesting you get a registration page. The reason is that there are some websites that allow Google but not unregistered or you. The solution is to disguise yourself as Google changing your browser's identity (named user agent) to Googlebot.
Internet Explorer
Copy this code into notepad and save it as a .reg file (name it googlebot-useragent.reg for example) or download and un-zip this file
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
Internet Settings\5.0\User Agent]
@="Googlebot/2.1"
"Compatible"="+http://www.googlebot.com/bot.html"
Now double-click the .reg file you've created (or downloaded) to merge it into Windows registry. In order to restore the default user agent copy this code into notepad and save it as a .reg file (name it standard-useragent.reg for example) or download and un-zip this file
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
Internet Settings\5.0\User Agent]
@="Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)"
Now double-click the .reg file you've created (or downloaded) in order to change back to the default user agent.
Firefox
Type in about:config in the address bar and down to find "general.useragent.extra.firefox".
Double click on it and type in "Googlebot 2.1".
This will change Firefox user agent to the google bot. To change the user agent back to the original click Reset to restore the property to its default value.
Opera
There is no way to change the user agent to Googlebot in Opera at the moment.
