At work we had to change the homepage of all browsers for students for convenience reasons and so I wrote this VBScript, which is my first ever, so it could be made better maybe, but it works great – I seem to fall in love with it
. I only wrote the script to change Firefox, Chrome and InternetExploder settings, because only those browsers are available on computers accessible to students.
The script was put in the Logon script of our Domain to run every time a user logs in.
Whole script can be downloaded from
here and I’m posting the code for quick review
