I recently installed Windows 7 on my MacBook Pro and everything runs fine, however at all times there is a svchost.exe process that stays at 50% CPU usage. I have installed all updates and tried clearing logs. I don't feel like that is normal because I've used Windows before and when doing nothing the CPU has been idle.

I had this problem, too, last week. I realized that this is a pretty common problem with Windows Updates.

This HowTo from wintips.org helped me. More precisely, solution 4 step 1: delete SoftwareDistribution folder.

Microsoft seems to have a fix for this problem in this KB article, too.

Ok, after some months of trying different howtos, I managed to solve the problem permanently with the help of this website (it's in German, in case someone is interested). I am sharing this, because nothing else has helped me, not even highly-rated howtos on this site.

Follow the steps below and pay attention to choose the proper KB with 32/64 bits, as you need it, and the correct language for your installation. Because of this combinatory explosion, I don't offer direct links here.

  1. Disable automatic Windows update.
  2. Download and install KB3078601.
  3. Download and install KB3205394.
  4. Download and install KB3020369 (not sure, if you can skip this one).
  5. Download and install KB3172605.
  6. Enable automatic Windows update.
