http://www.topsecuritysite.net/ ..... is my homepage now wheather I like it or not !

Well, I've never used them, so I don't knwo But we can try registry fix if you tell me what site you want to be your home page.

 

www.google.com.au
thanks.

 

Let´s try this:

First make a backup from registry:

Start -> run -> regedit -> ok

Then File -> Export. Give it a name and save it

Then save text below as fix.reg in Notepad (save it as all files, *.*) on desktop:

REGEDIT4

[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main]
"Start Page" = "http://www.google.com.au"
[HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Main]
"Start Page" = "http://www.google.com.au"

Doubleclick fix.reg, click yes and ok. Reboot. Did it help?

 

It says cannot import fix.reg: The specified file is not a registry script. you can only import binary registry files from within the registry editor.

 

Are you sure that you save it as all files in Notepad (*.*, not eg. as text file)?

 

Yes, I saved fix.reg file in desktop and by selecting All files *.*
thanks

 

Try to replace "REGEDIT4" with "Windows Registry Editor version 5.00" and try again. Also make sure that there´s one empty line between Windows Registry Editor version 5.00 and [HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main]

 

It says,
cannot import c:\documents and settings...fix.reg:Not all data was succesfully written to the registry. some keys are open by the system or other processes.

 

Well, then there's only one option. Open regedit and go to
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main-key
Create subkey Start Page and give it a value named http://www.google.com.au.
Repeat same thing with this key: HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Main

 

It says,

"Cannot edit start page:error writing the value's new contents"

thanks

 

Ok, then I guess that you have only two options. Use system restore to revert back to time when you had no home page problem or do repair installation of windows. Also make sure that you have priviledges to that key in regedit (edit -> priviledges).
