Update problem wauserv eating 50% cpu can't change updates settings

I stopped the wauserv and cpu usage went down to under 10 percent but this is only a temporary fix.

Now it is time to do the KB article for Windows update, whicxh will give you the file needed to do the replacement. Then run the Windows Oflline Updater. Again, you may need to do a completely CLEAN install using the tutorial that Brink has here on the Forum to make sure that Windows 7 is OK. Even then you will want to install what I am suggesting anyway.

I can't do a clean install. I only have an upgrade disk. I don't want to lose all files, and don't want to go through installing everything again. I have been dealing with this for 2 weeks, it is driving me nuts.

No need to reinstall windows.

RE: Greyed out options. Delete the following:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU

additionally on a 64bit machine delete:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Policies\Microsoft\Windows\WindowsUpdate\AU

Only delete the AU subkeys.

Reboot.

If you want to do a full removal and reinstall of windows updates there's a way to do it but it is:

1) Complicated
2) Will drive you nuts
3) May take at least three days to do it properly (fixes need to be applied in order and plenty of reboots are required)
4) May take multiple attempts to get it right

Thank you, will that allow to change settings in win updates? Why do you think it is saying some settings can only be changed by admin since I am the admin already?

What is with the wuauserv taking up 50 percent of my CPU? Will deleting as instructed above help solve this?

I do not want full removal of updates or windows altogether. My computer runs great now since I have turned off the wuauserv, but now I don't have any updates.

Hi and welcome to SevenForums,
Ran into this which has near the bottom a fixit for me listing
https://support.microsoft.com/en-us/kb/883821

I tried that but this it what is says:

"This easy fix does not apply to your operating system or application version"

There are several fix's listed only one was for your error code.

Either way sounds pretty bad
You can indeed clean install with an upgrade activation key with option 3 after following option 4
Clean Install with a Upgrade Windows 7 Version

I only tried the one that applies to my problem, didn't work.

I really don't want to re-install Windows. I would rather stop wuauserv every 30 mins and live without any updates.

You might try option three of this tutorial:
Windows Update - Reset

After the reset, manually install the latest Windows Update Client:

Set the computer not to sleep and let it search for updates for as long as it takes.
