text:  CrowdStrike has now issued a fix, stopping short of an apology. The suggestion is that every single affected machine will need to be manually rebooted in safe mode, which could take quite some time. There will undoubtedly be serious questions at Microsoft as to how this error managed to sabotage its usually robust systems quite so dramatically. There's no suggestion that it was a cyber attack or a hack, and no one's data security is believed to have been compromised.
