Kelvin, what browser are you using? Also, do you use an account with administrator privileges or are you using a limited account? Do people have their own accounts or is it shared?
Two answers to your question:
1- you can enforce your home page using group policies (on active directory) or local policies (on a computer that does not log on to a domain) to enforce a home page and to prevent changes
run gpedit and look at user config-admin templates-windows components - internet explorer. You can also use this to control a lot of other settings, but THINK about what you are doing - you can make your own life difficult
2- If your homepage is changing, it may be that it is a spyware program or a worm, rather than another person. Hunting these down requires a good tool and a bit of knowledge, so get the IT guys to check it out (normal AV may not pick it up).
Note that use of gpedit assumes you are using Windows XP if I remember correctly... Windows 2000 may not have that utility loaded (just like it is missing MSCONFIG!)
froginabox is correct. please let us know what account are you using. Is it an administrator account or a limited user account?
Here is my own suggestion;
If you dont know what account you are using right now you can use some software or programs to lock your computer. But since it is publicly used it is the hard thing to do coz others wont be able to save their files on that computer without having to inform you.
Or if you are the administrator of that computer, you may use that lock software but be sure to have an open partition or an extra disk for saving files and documents.
Before I continue, please let me know first what account you are using so I can help you better.
I've just run gpedit.msc.
It's full of stuff, with no apparent search facility.
Where in all this maze did you manage to disable homepage change?
I'm just thinking this issue had been closed. My suggestion is to close this topic because there was enough answer to the query and working quite good.
cannot we use group policy in home edition ?
