SetDefaultBrowser

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 the hive and browser of your choice. Since the version 1.3 there are more parameters and it might look complicated, but it gives you actually much more flexibility. Just run SetDefaultBrowser without parameters to get a list of all available browsers:

as you can see, i have a ton of Browsers on my system and using the following examples i can change the default Browser:

SetDefaultBrowser.exe HKLM Firefox-308046B0AF4A39CB

this will set the x64 Firefox as my default

SetDefaultBrowser HKCU “Google Chrome.HEYY3KJOYOAJOPVCHWOFAPMTPI”

this will set the Chrome that is only installed in my AppData as my default

SetDefaultBrowser.exe HKLM Edge delay=1000

this will set Edge as my default browser, but will wait 1 second until it executes. delay must be provided in milliseconds.

SetDefaultBrowser.exe HKLM IEXPLORE.EXE group=IE_Users

this will set IE as my default Browser, if i am member of the IE_Users group

i hope these examples explain the possibilities and parameters clearly. if a browser identifier contains a space, you must use quotes – for example “Google Chrome”. the same applies to group names (but you also can use Domain\Group or [email protected]).

to maintain limited compatibility with the older versions of SetDefaultBrowser, i have added shortcuts to the most used Browsers

SetDefaultBrowser.exe chrome

this will set Chrome as my default Browser, when its available in HKLM

SetDefaultBrowser.exe ie delay=2000

this will set Internet Explorer as my default Browser but delays two seconds before

SetDefaultBrowser edge group=EdgeUsers

this will make Edge the default if the user is member of the EdgeUsers group

available shortcuts are: chrome, ie, iexplore and edge. i had to skip Firefox, since you can have multiple Firefox installations (for example x64 and x86, like on the screenshot above) and using the hive and browser parameter, you can better specify which one you want to set as default.
