Validity/CoverageValid as of: Apr 2016 (2016-04-12)
Valid until (presumably): May 2016 (2016-05-10)
This HowTo is valid for Win7 SP1 and Vista SP2, which have been newly installed or haven't been updated for some time. It should also help on systems that were up-to-date last month - just install the missing updates from the list below in this case.
These instructions were only tested on Win7 SP1. However, the list of updates should speed up the search for updates on Vista SP2, too.
Solution to the issueInstall the following updates BEFORE letting Windows search for updates, to avoid this very search taking "forever":
|KB||Win7 x64||Win7 x86||Vista x64||Vista x86|
|KB3078601, "loyal" companion since August 2015||Download||Download||Download||Download|
On newly installed Win7 SP1 systems it's not really necessary to install the updates from the list above; it's sufficient to install any of the current Windows Update Clients (December 2015 or later) from the table below. But since the updates from the list will be installed automatically anyway, it doesn't matter if they're installed manually beforehand.
To reduce memory and CPU usage while searching for updates, the following updates should be installed as well:
- Windows Update Client
It's sufficient to install one of these packages:
KB Win7 x64 Win7 x86 Win8.1 x64 Win8.1 x86 KB3075851 August 2015 Download Download - - KB3083324 September 2015 Download Download - - KB3083710 October 2015 Download Download - - KB3112343 December 2015 Download Download - - KB3135445 February 2016 Download Download - - KB3138612 March 2016 Download Download - - KB3138615 March 2016 - - Download Download
- The following update is (most likely) not required if the Windows Update Client of December 2015 or later is already installed:
KB3102810, reduces Update Agent's CPU load.
Steps to take after Windows installation
- Disable Automatic Updates:
Start > Control Panel > System and Security > Windows Update > Change settings > "Never check for updates"
- (Optional) Stop "Windows Update" service: Open Windows Task Manager > Tab "Services" > Right-click on "wuauserv" > Stop service
- Download the updates mentioned above and install them via WUSA on a CMD shell (as Administrator):
"%SystemRoot%\system32\wusa.exe" "C:\full\path\to\Update.msu" /quiet /norestart
- Reboot the system.
- Now let Windows search for updates, which should be finished in less than 15 minutes.
- Re-enable automatic updates (see step to disable them, but select one of the options to check for updates automatically now), and install the remaining updates as usual.
