Re: Time for another 6 hours of lost computer time
Ideally, Microsoft and Apple would slow their release schedule for new OSes to a sensible pace (perhaps one major version every two to three years). I've not included Linux because most distros seem to follow a sensible release schedule. Unfortunately, the current development trend, which seems to have been largely instigated by Google seems to have force both Apple and Microsoft to increase their OS release cycle to one major update a year with minor updates more regularly (in the case of Apple, every 6-8 weeks).
I feel a slower release cycle would enable the vendor to get rid of more bugs BEFORE release, not after.
These bugs need to be fixed, which leads to a problem. Do Apple and Microsoft release potentially dozens of patches each fixing a few bugs, but has little risk of breaking something else, or do they bunch together the fixes in one (or more) larger patches that fix dozens of bugs, but slow the install, and introduce the potential to break other stuff.
That said, I think if a machine is taking 6 hours to patch ANY OS, there is a problem with the install. I just did a fresh install of Windows 10 1809 on a VM. I kept the VM off the network while installing, because I didn't want it to install any updates before I could time it. It took 43 minutes to get this fresh install of windows 10 to the point where it had installed all updates. This included a feature update to 1909.
