I want to copy the update content folder.
If your main disk is C:, this is the path
Whenever Windows updates website scans and install any updates or patches, it gets stored on the below location.
go to run and type %windir%softwaredistributiondownload
Depending upon the updates different folders gets created on the above location.
use Windows Update Catalog. Insert the KB codes for each of the updates displayed in your Windows Update and add them to the basket. Once all updates added, download.
Note however some updates are required to be installed in a certain order. This is definitely true for updates with different release dates. Managing all this after a few months can become nightmarish.
