Who eats the processor?

Question

Windows

Hello.
I have an old Pentium 4 and Windows 7.
For some time now, someone began to eat percent.
Outwardly, it looks like svchost.exe taking up 100% of the CPU time.
I tried to climb the services and found that when the Windows Update service was disabled, the symptoms disappeared.
Well, also a solution, but a strange one.
Actually the question is: who is to blame and what to do?

Answer 1

Well, the update center is to blame, is MSOffice installed? Usually, its presence in the system causes such winupdate-causing behavior.
But there’s no way to fight, except to try to crash the updater’s cache (stop the service and delete the C:\windows\SoftwareDistribution folder)
Usually it only once stresses the system so much, you have to wait until the end, then it will load less

Answer 2

The update service is quite gluttonous even with the installation of all possible updates. Luckily, this only happens right after the updates are installed, and not for too long. It's just that on multi-core processors, users do not notice this at all. Yes, and the installation usually takes place only once a month. If this service loads the processor every day and more than 10 minutes, then this is precisely the lack of a patch that MaxKorz wrote about . And even if this patch is not available, the update center will install it itself if auto-update is enabled, but this may well take 10 hours of 100% kernel loading.

Answer 3

I advise you to immediately install superuser.com/a/997067 for the future, then https://support.microsoft.com/en-us/kb/3125574 - a little faster than a separate unofficial collection of updates.
windows 7 can find updates anyway, but it will take a very long time when 1 core is fully loaded. known problem, repeated in xp, vista, win7.
