100% Disk Usage in Windows 10. Some of the proposed methods (method with registry editor) due to carelessness can lead to problems with the system boot. Despite the fact that this reason rarely causing high HDD usage in Windows 10, we recommend you to start with it, especially if you are not an advanced user. My Windows 10 CPU Usage is always very high, near 100%. Usually it is the Antimalware program. So, I end the program because I don't need it, but my CPU continues to be at 100%.
What is SuperFetch In Windows 10 and what does it do?SuperFetch is an that analyzes usage patterns over time to optimize memory content. It was initially introduced in as a successor to PreFetch, found in Windows XP.With the help of a lightweight tracking algorithm, Windows 10 Superfetch process builds a cache profile of applications and programs.
These are applications which you use most frequently. For example, the ones you opened first thing in the morning or the one you entered after a lunch break.SuperFetch takes notice of every application running on your system. When you exit a frequently used application, SuperFetch asks the system’s main Memory manager to give up some applications cache memory so when you start that program again, Windows 10 won’t have to run it from the disk and can load the program within a brief amount of time.Obviously, if you are using an SSD, you don’t really need SuperFetch to pre-load an application because programs run extremely fast on SSD in comparison to HDD. Also Read: Superfetch and 100% disk usage in Windows 10?At this point, you might be wondering if Superfetch is so helpful then why the nagging process takes up high disk usage in Windows 10.To put it simply, the memory manager process itself takes some amount of RAM to run smoothly.
Moreover, it tends to run in the background as well.That’s not the only reason. Sometimes, it can mess up on its own, not knowing when to stop or which process to pre-load. On bootups, it makes things even worse by running all the processes that could have been executed at a later point in time.Many users have repeatedly reported that Superfetch gets in their way while gaming, bringing frame rates down. Many also say that the Superfetch process results in unexpected spikes of memory, even at times freezing the system. Is SuperFetch Needed In Windows 10?

Should I disable it? Image:In the end, everything comes down to this question — Should I disable SuperFetch in Windows 10? And in doing so, will it have any consequences?Out of hundreds of processes that create issues upon disabling them, thankfully, Windows 10 SuperFetch is not one of them. Like I mentioned above, “Service host Superfetch” is merely a memory management process so even if you disable it, it won’t create any significant errors.With that said, it’s not an entirely unwanted process. Since it’s known to run the PC more efficiently, one might face issues like a slight increase in booting time, slower response upon opening programs and applications, and other minute bugs.But on the contrary, we are dealing with Windows 10 100 percent disk usage, which certainly can’t be ignored at all — especially when booting time shoots for the skies. How to Disable SuperFetch in Windows 10?Although there haven’t been any reports of users facing any significant change after disabling Windows 10 Superfetch, I’ll recommend you to err on the side of caution. If disabling Superfetch doesn’t give satisfactory results, turn it right back on.Now that you know everything about Superfetch, let’s look at how to disable Superfetch and get rid of high disk usage in Windows 10, once and for all –.
There are times svchost.exe takes up 80% of my CPU resources and hogs up like 90mb of RAM. The RAM usage shouldn't be a big deal as my computer has 4gbs of it, yet the system performance goes waaaay down. My computer is practically unresponsive.
I've isolated the problem to Sysmain, also known as Superfetch. As soon as I stop that specific service, the svchost host process goes back to normal system usage levels. What annoys me is that it does cause my computer to load faster initially, and it is for this reason which I leave it on - but after a few hours of usage, it turns around and causes unresponsiveness.
