WSUS is always missing lots of updates

Sorry to be a total clutz, but I use WSUS offline for a while. But even though I only updated the offline files recently, there are always lots more updates needed according to windows, after ive completed the WSUS client .
This happens on different computers for me

I tick as much as I need, ie windows 32 and 64 bit, windows 7, patches yes, include all options, etc

I run this from a flash drive and its using about 14Gb.
I haven't ticked "USB Medium" because im running it from a USB stick anyway.

So if you know why there are so many updates found by windows, after a new WSUS was run, I would love to know.

Also doesn anyone know how much time WSUS saves when installing a new windows 7 PC, because at the moment it doesn't feel like its saving much time.

I too am recently having similar problems with wsus. When I first discovered this program a couple months ago it was a godsend!

Now lately, however after running thru the whole process on several W7 machines I am repeatedly experiencing the same behavior.

It seems to build the client folder the way it should. After completing that phase. Then I run the updater as administrator and it appears to

go thru the whole process of applying all those updates like it normally does with no apparent error...

But afterwards I am now finding that all the updates are still needed by Windows Update...

Even after rechecking for them, the machine still insists it needs all 176 or more updates. And so I still end up now having to let windows

update run thru its normal process of downloading and installing all of the updates as if I had done nothing.

So I re-wiped this last machine and went straight to Windows Update without attempting WSUS. And yes it found 176 updates! Exactly!

disappointing, this is!

Hello sledgebeast,

What does the installation log on each system say (C:\Windows\wsusofflineupdate.log)? Did you reboot before running Windows Update? If the computer already was online before using WOU (not recommended) and updates were listed in Windows Update, it may take a while until installed updates (by WOU) are recognized by Windows Update.

Sorry I have already returned that machine back to its owner.

I will have to get the log for the next machine I perform a factory restore on if it behaves as the last few did.

BTW, I do this for a living and have since ~1992 when I started my business "The Computer Guys" here in BG, KY

However, I can answer some of the Questions tho.

No the computer was not already online. It and all other CPU's I do were just factory restored w/ no save.

ie. back to the "out of the box" state...

Next,,, All Bloatware and Trial AV's are then uninstalled & a reboot performed.

WSUS's zip file was then placed on desktop and then extracted.

Windows Update set to Check for updates but let me choose whether to download and install them &

I also uncheck Give me Recommended updates the same way I receive important updates.

Especially now due to Windows 10 & Crap Telemetry Updates Being slipped in as Recommended and Optional's

Power Mgmt set to Never Sleep! <<During the WSUS & all other updating processes>>

Ethernet Cable then and only then connected! I will note WU doesn't really get time to perform a check.

At this point I begin using your WSUS as described in the previous post...

As soon as WSUS builds it client folder for me I unplug from the Inet and check WU to see is still inactive.

Next I let WSUS perform it Update process including its reboot(s). "I always let WSUS Run as Administrator"

And yes I rebooted the computer 1 or more times afterwards trying to see if WU would then

change to show just a few updates as it has in the past, when we were happy with its behavior.

It does not. I then try clicking "Check for Updates" and after a lengthy time it comes back with still needing

essentially all updates... Again as if I had never used WSUS in the first place. Weird Huh?

And to restate. WSUS appears to complete with no apparent errors. Running thru 1 of 200+, counting them off as expected.

Side note: WU finds ~176 or more,,,,,, while, WSUS seems to always process numbers into the 200's wether it actually uses 200+ Why the difference, idk?
