Just one of the numerous threads, a recent one, about the joy of MS Store:
When I changed my Mother Board (and processor and RAM), from an old Asus to a brand new MSI, I formatted my 128GB SSD OS drive (it wasn’t mandatory, Windows can land on its feet like cats). I wanted a clean OS and registry. Steam was installed on another data drive HDD 1TB. When I first launched Steam after this, it just said “One minute guy, I fix a small problem” (more or less from memory), and Bam, all worked fine; all my games and all perfectly fine.
It’s solid.
