KB3138612 - Install or Hide?

Hi,

Could someone tell me whether it's okay to install KB3138612? Windows Update rates it as 'Important', but I'm wary of patches like these as quite a few have been linked to Windows 10, which I'm trying to avoid. Would it be better to hide it?

Thanks. :)

Thanks, Ranger4 and mjf. :)

Hi AddRAM,

I've read its description but am still not very clear as to what it's for, which was why I was holding off from installing it. My main worry had been that it was connected with Windows 10, but neither Ranger4 nor mjf seem to think it is.

Look again at the description:

KB3138612 This update contains some improvements to Windows Update Client in Windows 7 SP1 and Windows Server 2008 R2 SP1.

That it is recommended for Server is an indication that it is not W10 related. I too installed this on all my machines including my WHS2011 which is rooted in Server 2008.

After installing this update, I ran into a subtle problem. Manually running Windows Update works fine. However, frequently, svchost would use up about 13% of my cpu for a long period of time. Restarting the Windows Update service would temporarily fix this. I noticed that however the Windows Update service is being used, it is not through the standard Windows Update mechanism. Even if I tell Windows Update never to check for updates, it eventually gets into that state. Uninstalling KB3138612 fixes the problem. I suspect that this has something to do with the Windows 10 Upgrade mechanism.

Can you explain please what you mean by this.

The standard Windows Update mechanism would honor the directive never to check for updates. Indeed, on my Windows Update screen, the date last checked for updates never gets automatically updated unless I do a manual check leading me to conclude that something else is going on with the windows update service using CPU cycles. Windows Update is not the only software that can use the Windows Update service - the most likely suspect is the "Get Windows 10" applet or associated software.
