Google Drive Backup and Sync on Windows Is Horribly Buggy

The problems are myriad, the worst being on my daughters laptop the fan running at high speed because it maxed out the cpu. Other than that, I ran into about 10 serious bugs in the hour spent just trying to sync my cloud drive and my Google Drive folder on Windows 10. How is it that a trillion dollar company with 100,000 employees can ship such a terrible program. Don't they use it themselves on Windows?
