The Update doesn't remove any system restore points (not that you'd want to ever use them, in this particular situation). Windows will not let you restore back to an earlier release. Windows Updates are now like macOS yearly updates. That would completely trash your system. Going to Windows 1803 is more like going from macOS Sierra to High Sierra. The updates are huge, and they are not "Service Packs." Restores simply can't handle this properly. You have to use System Recovery to roll back a Windows Upgrade.RobertOZ wrote:Notice that the update to 1803 removed all the system restore points, as it happened, I had to restore back to the previous version of Windows, 1709, it appears that 1803 causes battery issues with Toshiba SSD, and my battery stopped charging
What Windows does, is archive your ENTIRE WINDOWS OS before the upgrade (this is why they take rather long, especially if you have a slow HDD), and you have ~30 days to Restore your PC back to what it was before applying the 1803 update - after that, Windows will automatically delete the old version, as it takes up a ton of space and they assume you're good to go if you haven't Recovered your system in a whole month. This is what the "Windows.old" folder on your HDD is after major updates - your entire Operating System, before the update.
If you want to roll back to pre-Update Windows OS, you don't look for System Restore. You look in the "Recovery" section of Windows Settings and roll it back to what it was prior to the update. The whole process takes a few clicks and a few minutes.
It has always worked this way since the release of Windows 10, because setting Restore Points across major OS updates is a recipe for absolute disaster.
System Restore is only useful for Application Installations and Cumulative Updates (basically what we used to call "Service Packs"). For Device Drivers, it is not useful (or rather, really should not be used), as you can target the specific driver you want to roll back in Device Manager without affecting the rest of the system (via the Driver Rollback function).
