I was surprised to find that System Restore in W10 was disabled by default. I enabled SR but then I received the Creators Update which promptly disabled it: I then re-enabled it. Why does MS not want System Restore to be enabled?
The only logic I can find is due to the size of HDD. In laptops/tablets they tend to have a small eMMC hard drive where system restore is turned off. Example: HP pavilion x2 has a 32GB eMMC HD, to do the Creators Update you needs to connect an external USB drive to allow for the update. If system restore was tuned on as default after the update it would cause a lot of problems.
