25% CPU usage, Windows 10 update?

[coolpurplefan]

I have Win7 and don't want Win10. Is my computer automatically updating? How can I stop this?

If your computer is prompting the upgrade to Windows 10, you will have the white Windows logo down on the taskbar by the clock. Additionally, remove update KB30335583 to prevent the notification.

Don't do that. We need to stop recommending these half-arsed methods of dealing with GWX. If you uninstall KB30335583, it will only get reissued at some point and you'll have to be constantly on the lookout for it.

Use this tool:

It's a GUI for the official Microsoft sanctioned method of disabling GWX reliably.

The 25% is probably going to continue. Windows Update regularly pegs one core (which is 25% of a quad core CPU - ignore the inaccurate graphical representation in task manager) when checking for updates. It shouldn't be doing it 24/7 though.

HELP! I clicked on the link up there and after being calm for a while my computer now is going up to 50% usage!!!

That's because the tool he linked didn't stop Windows Update from working. It just blocks Windows 10 from downloading (at least it's supposed it).

Windows update will use a significant percentage of your CPU. That has been a known issue for a while now. If your computer hasn't updated in a while, you may want to run the update rollup, located here:

Despite what others say, Windows 7 won't update to 10 unless you allow it to, but it is sneaky about it. For example, if you are about to hit the shutdown button, and notice the update icon to the left of Shut Down text, go to Windows Update instead and verify that you aren't installing updates you don't want (the Windows 10 Update has a pretty obvious description here).

Removing that update is the method I've used on more than 20 systems and it works perfectly. In addition, turn off "Recommend Updates" in Windows update settings. That's it.

If you want to remove the Windows 10 files that have already been pre-staged on your PC, just run disk cleanup.

Tons of guides online for doing all this stuff.

Do we even know what's using so much of this person's CPU?

Well, I just used that tool and now I feel like a tool myself lol. I may have to re-install Win7. Why? I clicked on that program above to re-enable updates because I decided I wanted to install the latest updates out of curiosity. So, what happened? It seems my Windows Update is broken. Besides, the free upgrade will expire on July 29, 2016 if I remember correctly. So maybe if I re-install Win7 and disable updates until July 29, maybe I should be OK.

Tap on the Windows-key, type cmd and hit enter.
Type powershell and hit enter.
Use the command get-hotfix -id KB3035583 to find out whether the update is installed
To speed things up, query for all updates in a single command like this:
get-hotfix -id KB3035583,KB2952664,KB2976978,KB2977759,KB3021917,KB3044374,KB2990214,KB3022345,KB3075249,KB3060746,KB3080149,KB3068708,KB3083324,KB2999226,KB3083710,KB3095649,KB3102810,KB3112343,KB3135445,KB3118401,KB3121255,KB3138612,KB3139929,KB3133977,KB3123862
Use the command wusa /uninstall /kb:xxxxxxx to uninstall a patch (replace xxxxxxx with patch number)

these are all the updates i have blocked so far.

this list is always being updated here..

Maybe the update process is just broke, try this:

it is funny how people now are genuinely afraid from the 'OPERATING SYSTEM' changing on its own without proper notification and warning to the issues that may arise, .. this shouldn't happen from a 'reliable' OS.

How different is that compared to a virus AND spyware ?

People do real work sometimes on computers, and can't accept the sudden change or unexpected compatibility issues.

I just used ATF Cleaner, TDS Killer, Ad-Aware, Malwarebytes and Avira and haven't found any viruses or anything. I may have to go to techsupportforums. The only "new" things I've done is get a new Internet Service Provider (Bell modem) and installed Razer Deathadder mouse. But both did not seem to pose any problem at first.

The get hotfix id command showed it's not even in my system.

EDIT: UPDATE, I finally was able to update Windows 7 after setting it to "notify about updates" or something like that. Anyway, right now it seems I'm good to go. I was able to play the Unreal Tournament pre-alpha demo again.
