what browser are you using >>
I use firefox, chrome and edge.
sorry for my Alzheimers memory
It was not in taskmaster I went.
After the browser asked to download & install widevibe,
then I would check that download, looking and seeing the folder on the system it was installed to.
Then I would shut down the browser, go that folder and delete any widevine files I found in that folder.
At that time my browser was Firefox and I found the widevine files in one of the Firefox program folders.
I am now using Brave and their are no widevine files in Brave’s program folders. I think Brave has widevine integrated in it.
Hope this helps.
