Download and Install Windows Update from Microsoft Update Catalog


Another way:
Download WHDownloader (Windows Hotfix Downloader) 2.2
Unzip to desktop or where ever then run.

1. Download the KB's list from catalog. Should run when starting the program to get the latest list.
2. Select Office/Windows edition
3. Put check mark(s) to select the KB's
4. Download Updates.

NOTE: The KB's with huge file size are normally the cumulative updates from one version to next. If you are currently running 1607 then you'd need to run the KB for 1073 first then run the next one (1709), The rest of the KB's are security updates, Flash Updates etc...
