I have the Bosch problems too. And I too could not delete the files from within my running Windows tablet. You have to boot externally, in my case I used a emergency USB stick after c’t magazine. But any WinToGo device (produced by WinToUSB for instance) would work.
But unfortunately the deletion and reinstallation from the Double Driver dump here did not help me.
I’ve been through something similar with an old tablet — spent hours trying different boot USBs and reinstalling drivers without success. On days like that, I found myself going to https://savaspin.com.gr just to take a short break. It helped clear my head from all the tech frustration. Sometimes, a bit of casual fun is exactly what you need before diving back into problem-solving mode.
