Upgrading/reinstalling some company specific software (it’s an absolute mess, we essentially build our own tools for everything in C++, there’s probably a quadrillion memory vulnerabilities and the software crashes all the time), because random people on the Windows team have been tinkering with the config over the years, and now essentially everything is broken and has to be reinstalled. We have been shipping newer versions of our software to customers than we were running internally… (of course it was tested in the staging environment, but our prod was pretty unmaintained and messy) I’m so glad that I’m usually on the Linux team… I was a software engineer before, but I was tired of C++ and the weird way we do things, so I was probably the first one who asked to move to the newly formed Linux team, when we started slowly migrating away from Windows around 6 or 7 years ago. Unfortunately like half of the Windows team recently quit or was laid off, so they had to find someone who could do this. Since I was a dev before, I’m quite familiar with our internal tools. I’m now working with 3 Windows guys on fixing this insanity. The entire process is not quite as bad as it sounds, but I really don’t want to touch a Windows system ever again in my life.
