Windows 7: High idle CPU temps after last updates

Windows 7 Ultimate x64
High idle CPU temps after last updates


It happened twice. My CPU idle temps increased A LOT after windows updates (Ultimate 64). And not just after rebooting, but all day long. Just in idle. When I start any work on the laptop, it drops to normal levels. Scary, cause I make pauses often and let it shutdown the screen and sleep. What a surprised when I return to work and check it reached 70C when it was supposed to be cooler than before, obviously. Once I touch the mouse and resume working, it drops fastly and everything seems to be normal. WTF? And its happening only after updates, and only on Ultimate, because when I had Home Premium it never occured.
Thanks in advance for any help, and sorry for bad english.

Well you didn't do the same updates on the HP as you just did on Ultimate.

In any event maybe one of the updates is running something when the system is idle and or it has fooled with the SpeedStep function and or fan controls so they don't turn on when idle. Once you start using the system the fans turn on and cool the system down.

Uninstall the latest updates and see if that fixes it.
If it does then do one update at a time until you find the one that is causing this problem.

This is a great idea, for sure!
As for the fans, they work when idling, I checked it myself. Anyway, Ill install the updates step-by-step mode and try to catch the fiery one
Thank you!

Very high CPU usage, causing very high laptop CPU temps (90c idle)
This problem began yesterday. I noticed my CPU was at 90C constantly with very high CPU usage (>50%). I had no major programs running. I rebooted several times and the program persisted. 1. I went into safe mode and everything was normal. So this rules out hardware issues. 2. I reformatted and...
