It is 2020, what was the customer data and critical systems doing on Windows boxes, rather than Linux with a snapshotted file system underpinning the storage?
At the places I have worked since 2006 this kind of ransomware would mess up finance, HR etc. But the real customer facing work would be unaffected. And those affected systems would be rebuild with a clean client OS and up and running relatively quickly. Once HR and the bean counters figured out how to recreate their shortcuts, so over a week sounds reasonable...
