- @Imacri: I highly doubt it that it's the fault of "Wuaueng.dll" and "Win32k.sys" ONLY. Because reading the articles of "Woody " at www.infowolrd.com gives me the distinct impression that it's a combination of - at least - one more thing that's "buried deep" in the Windows OS.
I don't recall saying that the Windows Update Agent (wuaueng.dll) and the Windows kernel-mode driver (win32k.sys) were the ONLY cause of the slow Windows Updates. Did you read Dalai's background information at http://wu.krelay.de/en/info.htm about the Windows Update Agent, the update catalog wsusscn2.cab and supersedence chains or follow the other links I provided in post # 16 to some of Woody Leonhard's articles? Dalai notes at http://wu.krelay.de/en/ that his workaround to pre-install the kernel-mode driver updates each month "only tries to make sure that the Update Agent doesn't need to check all updates" in the supersedence chains, but that doesn't mean that win32k.sys is the cause of the slow Windows updates.
I do still believe, however, that an update to Vista's Windows Update Agent (WUA) v7.6.7600.256 (last updated June 2012) could help speed up the slow Windows Updates, especially on systems with slow CPUs and limited amounts of RAM, even if it doesn't completely eliminate the problem.
Woody Leonhard is recommending that Win 7 SP1 users affected by these slow Windows Updates now follow the instructions in Canadian Tech's thread Windows 7 Update Solution in the MS Answers forum - see Woody's comment's in his 04-Sep-2016 AskWoody.com post MS-DEFCON 3: Get Windows patched, gingerly. The optional KB3172605 update (July 2016 monthly update rollup for Win 7 SP1 and Windows Server 2008 R2) recommended in Canadian Tech’s thread is a bundle of six separate non-security hotfixes, including KB3161647 (Windows Update Client for Windows 7 and Windows Server 2008 R2) that updates the Win 7 Windows Update Agent to v7.6.7601.23453 and includes "An optimization that addresses long scan time for updates" and a fix for "Windows Update error 0x8007000E". Unfortunately, Microsoft has not released an analogous patch for the Vista WUA.
Win 7 SP1 users who want to try Canadian Tech's solution to install the July 2016 monthly rollup KB3172605 should be aware that some users have had issues with Bluetooth connectivity following the installation of this update, which is a known issue for the KB3133977 bundled inside this rollup.
32-bit Vista Home Premium SP2 * Firefox v48.0.2 * NIS v220.127.116.11 * MBAM Premium v2.2.1
