I'm having problems with windows update svchost.

Update will not check for updates, or downloads show 0 downloaded. Previously a whole batch were downloaded but shown as cancelled in history. One of the updates is windows 7 sp1, but it is already installed.

After stopping update, svchost keeps running and uses 50% or more of cpu, slows everything down and fan keeps running. The only way I’ve found to stop this svchost is to restart.

I have reinstalled windows and the ultimate factory reset with no luck. I have run mbytes, avast and rkill but no problems found. Also chkdsk and sfc scanow.

I have tried to find how to remedy the problem on the net, but I can’t understand it, old age I’m afraid. Can anyone help PLEASE, in plain easy to follow language

Would be very grateful

Thanks, Ron

Hi Ron,

there's a chance that this is not malware, but a problem with windows updates.

Could you try to install this update manually and see if that helps:

Hi Sillyberry,

 

Thanks for quick reply

 

I ran the update client and three probs were fixed but I had "0x80070057 error can't be fixed"

 

I'm wondering if my laptop is past it's sell by date, getting a few problems recently. F3 key doesn't work on registry search and WIFI keeps dropping out showing no connections available, I reset the router but it happens again after a while. All niggling things but a pain after a while. I guess I may need a new laptop but on a pension it isn't easy

 

Regards

 

Ron.

Forgot to mention, it's a Toshiba Satellite 650c.

 

I'm not too clever on these things but could a low cmos battery be causing problems?

 

Ron

Hi,

I would not think that this is a hardware issue, they sound more like software problems. So you could probably fix it all by reformatting and reinstalling Windows. I also doubt that a low cmos battery would be the issue. Have you been noticing other problems like wrong time stamps etc? Those are typically indicators of a low cmos battery.

Did you try to install the update manually, or through windows update?

Please try and see if Windows-Repair will help:

Hi all
I did a factory reset from disks, which formats disk, would this have wiped off any nasties in there? Also ran Windows rescue disk I made when I got laptop. Downloaded wui and ran it...no luck.
Wifi connection keeps dropping out then restarting, no wifi connections available and I used to see nearby wifi connections but they don't show now
Would a wifi usb overcome my problems?
Regards
Ron

Hi,

When did you do the factory reset? If you just did a factory reset, then yes that should have removed the nasties. Are you in the process of reloading all updates now? If so I would recommend that you repost in the Windows7 forums, where someone will be able to help you more efficiently.

From the description it doesn't sound like malware, at least.

I'm totally bemused. Windows update wouldn't work and diagnosis came up with an error that nothing would resolve. A couple of days later as I turned off laptop it said 234 updates  were ready to be installed. It took some time as you can guess, not all were installed and each time I tried to turn off it said so many updates were ready to be installed, this happened again and finally all updates were installed, all 234 of them.

If I didn't know better, if I do, I would think someone else was controlling my laptop. I downloaded who's on my wifi and it seemed all clear
