My laptop has been running very slowly for the past few days which is weird because my laptop is quite powerful and has always run very fast. I looked at my task manager and saw that a process called Service Host: Local System was using up almost all of my RAM. I am running Windows 8 Pro on a Sony VAIO S13P. What can I do to fix this problem?

Hello.
I encountered the same issue and performed the first method that you recommended; it returned a message stating that Windows found some corrupted files but was not able to delete them. A CBS.log file was created but it's quite long and not very easy to understand; which is the next step that I should take now?
Thanks in advance
Remember this when running the scan... It takes a good amount of time for it to run!!! 😝
My CPU was running at 35% and the Service Host: Local System was running at 33%. There were 20 items listed under the Local System. The only way I was able to solve it was by running Norton Power Eraser. The number of items listed reduced to 17. Service Host: Local System now stays at 0% CPU usage and total CPU stays around 3%. I do not know what 3 items were removed. But this solved the problem.
Unfortunately, none of these suggestions help. Some of these sub-services can be stopped and others usually can't. In some situations, though, I can stop the entire service, but then it crashes my PC. The problem remains upon reboot.
I spent a few hours on the phone with Microsoft support in order to solve this problem, and they, too, were baffled by it.
The good news is that I finally got it solved. BUT, upon their suggestion I had to do a fresh install of Windows 10. I was apprehensive about it, but the rep assured me that I could do it without harming any of my personal files. So, while on the phone, I went ahead and did the clean install (I had previously upgraded from Windows 8.1 to Windows 10 months ago). The system clean install process assured me that none of my files would be altered. That's an issue up for debate!
Upon the fresh install, the problem with that processes constantly using high CPU went away and never came back! HOWEVER... while my personal files were preserved, all of my Windows Live email was wiped out! So were all of my installed applications. The application restore was a pain, but within a few hours I had most of them reinstalled. But I really hated to lose my saved email. I wish I would have been warned about that, since I considered that data part of "my personal files".
In conclusion, because the high CPU process problem went away, and most of my old software was reinstalled without the problem returning, I'm concluding that the problem was not due to my hardware or installed software, but rather to a problem with Microsoft's update from Windows 8.1 to Windows 10. Others in the past have recommended a "clean install" of a new operating system. I now strongly support that recommendation.
just go to control panel and select services navigate to something like background intelligent transfer just "STOP" the service you are done. if u again see the same issue try repeating the same because it will automatically restart after boot.
hope this may help a lot..
