SetDefaultBrowser – Set the Default Browser per command line or script

UPDATE 16.12.2017 – Version 1.2 now supports Windows 8/8.1 and Server 2012/R2.

UPDATE 10.12.2017running Windows 1703 and newer, you can now use my SetUserFTA utility to change the default browser. Just make sure you set .htm. html, http and https properly. 

if you are into XenApp, RDS or VDI, then you probably know how difficult it is to configure the environment properly for the enduser nowadays. in my latest blog article, i showed you how to configure File Type Associations per User. based on this previous work i have created a utility that can do the same for the Default Browser.

the story behind is pretty much the same, but to set a Browser, additional Registry Keys are needed (they are protected with the Hash like the Filetypes). the only difference is, that Microsoft also checks the path of the Browser (and hashes it too). for that reason i decided to create a separate tool to make it as simple as possible.

newer windows builds don’t need the path of the browser anymore and therefore the hash changed too – but i have updated my tool to support all possible combinations:

  • Windows 10 x86/x64 Build 1607, 1703, 1709
  • Server 2016 Build 1607
  • Windows 8 and 8.1
  • Server 2012 and 2012 R2

if you want to know more about the technical details (how the hash is calculated), please read my previous blog.

how to use

its really simple. just run SetDefaultBrowser.exe in the user context (there is a list of possible ways in my previous blog) with the browser of your choice as parameter.

SetDefaultBrowser.exe browser optional:group

i support five browsers at the moment. if there is a request, i might add more in the future (i did only test with actual versions available – November 2017). of course you need the browser installed (on local machine, not user). checks for the existence of the browsers are limited and the tool will change the registry, even if a browser like is not present (like edge on Server 2016 or LTSB).

it will even find the browser when it is not installed at the default path. Firefox was a pain to implement, because it uses three different types of file handlers (x86, x64 and something that  i call legacy). i tried to make it as dynamic as possible to support all possible versions. if you find one that doesn’t work, please let me know.

following browsers are supported:

  • chrome
  • firefox (shortcut ff)
  • iexplore (shortcut ie)
  • edge
  • opera

Example:

SetDefaultBrowser.exe ff

this will set firefox as default browser for the current user.

SetDefaultBrowser.exe firefox “Firefox Users”

will set the default browser to firefox if the user is member of the “Firefox Users” group. if the group contains a space, you must supply quotes. you can supply the group with the domain name like DOMAIN\Groupname or in UPN format like groupname@domain.tld.

the easiest way in an enterprise environment is to use the Group Policy Logon Script feature, just like in this screenshot (you need loopback mode activated, when deploying to computers):

bugs? requests?

if you find a bug or have a special request, you can send me an email to bugs@ mydomain (the one in the browser address bar).
