The company was large enough but the problem was due to an update the day before, and we discovered it as the computer was being started up about ten minutes before riding in a crash car The computer was our data recording device, and suddenly everything that had been OK two days earlier was no longer OK.How large of a company is this? If properly prepared, all updates (not just OS) should always be able to be successfully reverted. If not, you put your livelihood at risk. Note that I didn’t specify Windows; this principle stands for ALL software upgrades.
And you can not imagine how much a crash car crash costs. Fortunately we were not the auto company running the test, so we only lost our data. That auto company does not use MS anything for their crash data system. It was explained to me that they simply could not afford unreliable software in the crash test area. That says it all, doesn't it?
