Problem/Issue/Symptoms
In LANDesk Patch and Compliance, even though all the Microsoft Windows definition types are selected, the hotfixes released from Microsoft are not available, or there are just a limited selection of them, and they must be manually download.
Cause
Microsoft updates offer packages for general distribution release (GDR) as well as QFE (Quick Fix Engineering) also known as hotfixes, for specific issues.
QFE (Quick Fix Engineering) is a group within Microsoft that produces "hotfixes" - code patches for products that are provided to individual customers when they experience critical problems for which no feasible workaround is available.
Hotfixes are not intended for general installation, since they do not undergo extensive beta testing when they are created. Microsoft targets hotfix support toward enterprise-level customers and designs it to provide an extra level of security for mission-critical software systems.
GDRs are tested to a greater degree than LDRs (Limited Distribution Release). LDR, also known as hotfixes or QFEs, are created when a hardware, BIOS or a software issue is identified that needs a fix in a specific and small subset of customer environments.
These fixes have not been tested for the same length of time for regressions or incompatibilities as what a GDR fix typically goes through. Another key point is LDRs generally contain all the prior fixes from both GDR and LDR while GDR releases do not contain LDR fixes.
A hotfix is to fix a specific issue quickly while Microsoft Update GDRs are created to improve everyone's experience.
The reason why the hotfixes listed are manual definitions is that Microsoft doesn't publish them with a freely downloadable url but they have to be manually downloaded following some manual steps: Why certain vulnerability definitions require the patch to be manually downloaded?
