Even Microsoft admits that Windows 10 was put together in a hurry. The team started writing it in early 2014 — and released the first preview version to the public only nine months later. (By contrast, it took more than five years to produce the disaster that was Vista.)
So here we are, a month after its final release, and Windows 10 is still filled with bugs. Critics have noticed them, consumers have flagged them, Microsoft acknowledges them.
To be fair, there is no such thing as bug-free software. Every software company maintains a prioritized list of known bugs; as the shipping date approaches, they’re forced to draw a line. Anything below the line, they save to fix another day.
