hmmm
check your extensions
usually that's the first place I check for stuff that annoys me
quickedit:
also, keep an eye out for
ilivid
visualbee
conduit
searchprotect
and a lot of other stuff
those will ADD pop ups like crazy
if it's stuck on "Installed by enterprise policy", go to extensions, then "developer mode", and find it's ID.
enter regedit, go to edit, then find next.
paste in the code (copied or just put it in manually), then click "Find Next..."
it should show you a key in HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\ExtensionInstallForcelist
one of them should have the ID in the Data value
delete it and move on
next, enter chrome://policy
click on Show value... of the corresponding policy, and look for the folder,
ex: C:\ProgramData\lovingannoyingextension\
if show hidden files and folders are enabled, move on
if not, enable it
look for the folder, then delete it. it won't reinstall.
then, go to C:\Users\Your-Username (replace dis)\AppData\Local\GOOGLE\CHROME\USER DATA\DEFAULT\Extensions)
find the ID of the extension and DELETE IT
then, finally, go to C:\Windows\system32\GroupPolicy, and delete the Machine and User folders
no this won't help you with steam
