Updating your PC to the Windows 10 May 2019 update -- a major upgrade -- isn't necessarily click-and-go. I have a bunch of laptops that I'm in the process of (slowly) updating to the May 1903 update.
The Windows 10 May 2019 Update does not install on systems powered by AMD Ryzen or AMD Ryzen Threadripper processors with AMD RAID drivers prior to 9.2.0.105 and configured in SATA or NVMe RAID mode.
