do monthly rollups include previous updates
Microsoft calls this a cumulative rollup system where each monthâs update package includes all previous updates (going back to October 2016). The new monthly rollups will include both security and stability patches. On top of that, Microsoft intends to add older updates to the monthly rollup over time. Eventually, Microsoft wants to include every update between the âlast baselineâ for each operating system and the present. Presumably, that baseline is Service Pack 1 for Windows 7 and the Windows 8.1 upgrade for Windows 8.
