Maintenance :: Windows 8.1 - 100% CPU That Disappears When Open Task Manager
Jan 24, 2014
I updated to Windows 8.1 last month. It was quite smooth until some issues started 2-4 days ago. I don't remember if I have done something that may cause this, but I'm quite sure that I didn't make any change to the system.
The problem is, even when I am not opening any applications, my fan suddenly blows very strong and makes loud noise. From the CoreTemp utility I notice that CPU usage is 100% and its temperature is much higher than normal.
Again, this happens even when I am not opening any applications, and have started the computer hours ago (so it's not starting up).
The most strange thing is that the problem is solved completely when I open task manager. The first thing I see after doing that is task manager itself is taking up ~60-70% CPU, but that number goes down very quickly, and the total CPU usage drops to normal. The temperature shown in CoreTemp drops also and the fan becomes quiet.
Another issue with my current computer is that when I open certain applications (for example, Google Chrome), the process of the application appears in task manager, but in the background. And the application does not show up until 10-20 minutes later.
And when I use Windows Media Player, every song is stucked for ~5 seconds before being played. And there're spikes in the sound.

Since yesterday, I cannot open any folder on my PC and when I try to open task manager to close explorer, it closes right away.
When I try to open any folder (This PC or Downloads for example) my background flashes black, then the task bar goes blank and then nothing happens. When I try to open the task manager, it opens for 2 seconds and then closes itself down. All my files are still accessible since I am able to still play movies from WMP and I can still search from the Start screen.
I do not want to format my PC just to get something like this working again.
OK, I've noticed that what's happening is, explorer.exe pretty much restarts every time I try to open a folder. And that obviously stops the folder I'm trying to open, from opening. What's happening with task manager.

I've been loving the new Task Manager, it's better in every aspect except the time it takes to use. 1 minute is not acceptable for anything that isn't Skyrim, it takes so long that at first I assumed I hadn't pressed the keys correctly.
However it's much faster to open the second time, so I guess some process stays running after it's opened the first time. I wouldn't mind slowing down my startup a bit if it allowed me to have that process already running so when I open it the first time it takes a second.
Which process it might be and how I can set it to execute on startup? I'm not trying to open Task Manager on startup, just whatever makes it open faster.

My brother just emailed me, he's just installed update 1 from Windows Update correctly and it's rebooted to a black screen and cursor only - nothing works, safe mode is no different - can't open CMD or Task manager
Can't seem to get Advanced options > System restore, PC keeps only giving F8 safemode options, none of them work
He doesn't have any 8.1 Media either. How to get him back into Windows ?

I just got a new laptop with an i7-4700mq in it.. 4th gen Intels.. what does task manager performance tab show? Mine shows the processor at 1% usage, but the speed up at 3.2 GHz which is turbo boost speed I think..
See attached picture for what I mean. I just remember my previous laptop (i7-740qm) would show it throttling right down to less than 1GHz when nothing was happening. I have the latest drivers.

I've added task manager to my scheduled tasks at logon. Everywhere I google, they say to put the /min or -minimized arguments in it to launch it minimized, except neither option works for me. Task Manager launches, but just sits there on my desktop.
Is there a new argument for minimized in Windows 8?

I bought a new desktop last year to run high-end software used for my degree; I installed Windows 8 on it, having got on with it on my laptop. I did notice though, after venturing into the Task Manager, that my CPU usage was at 100%. All the time. Even when idle. In fact, resource monitor says it's working at 108% load! I thought this was rather odd, so investigated further:
It appears that task manager divides the 100% usage proportionally between the processes using the CPU. So for example if Firefox, Word and Notepad were using 5%, 3% and 2% respectively, Task Manager would report 50%, 30% and 20% usage. I was initially concerned that my processor was going to take some serious damage to its life expectancy if it was being constantly loaded - but the performance monitor in Norton Anti-virus shows the CPU load to be much, much lower - where I'd expect it to be.
My system is an 3.4GHz i7, with 16GB RAM running 64-bit Windows 8 Pro. People have suggested a fresh install, but it's difficult tobackup everything up and re-installing VPN servers and software through various security measures, so I'd rather not...

Considering the issue with Windows 8 restore points getting deleted, I decided to use Task Manager to create a new one weekly. The problem is that if I do not boot into another partition or manually delete the old restore point, they are going to pile up. Is there a way in Task Manager to delete the old restore point before creating a new one?

My task manager is showing an unusually high CPU usage by the system, anywhere between 20-30% when the computer is idling. I've run the sfc /scannow utility and it found some corruptions, which were then fixed by the DISM utility. However the task manager is still showing that super high CPU usage and no amount of restarts is changing anything. I've attached an image of my task manager.

When CPU usage is just high (50% to 60%) and I open Task Manager, it's usually McAfee on access scanner at work because I've just clicked an emoticon or something like that. Other examples are service host -- some long winded process I can't always find in the TM list to get the name right.
But when it's 100% and this has happened consecutively for over half a dozen attempts to find what spikes this, I'm dead serious: CPU usage has dropped immediately to under 3%. Yesterday and today I've "caught" this thing 2 times. CPU usage drops so fast you can't see what spiked it.
There are 2 Google Ads that pop in right about here but don't show up when I edit the post. These do not work, find hundreds of non-existent "errors" so that you'll buy the program and then when you run it you might get less than half a dozen errors fixed. Don't trust these programs, I don't. I have no control over what Google Ads does but I'd call it anything but "Adsense" to be honest.
I had Norton trial as the default AV when I first fired up and set up the laptop but I'm a McAfee person so set this up and removed Norton during the McAfee setup process. So it's not likely this is an infection. I apply all updates as soon as I see them, if I'm working and can't quit at the time an Update notice comes through then it's no more than overnight that these are applied.

I recently needed to kill a "SYSTEM" process in task manager, but of course "Access Denied".
It was ekrn.exe or Eset Service, I don't know how it got in there I haven't even installed any of their products.
I tried ending the process, tried through Command Prompt, but nothing worked.
So I ended up uninstalling Nod32(Which IDK how it got in my computer).
I am wondering, If I am an administrator of the PC why do I not have complete control?
I really want to kill those SYSTEM processes and they aren't even SYSTEM sometimes like this case.
Is there any way to kill them?

While using the computer, periodically when I go to the start screen and search for something, it just hangs for about 20-60 seconds before responding. Now today, every single time I start the computer, it loads fine gets me to the start screen, but if I type anything for the search then it freezes on me for 20-60seconds. If I start it and immediately go to the desktop, I can run SOME programs like IE or Chrome but NOT Ventrilo or games (for 20-60 seconds). Also, TASK manager will not come up nor do any of the windows 8 "charms" work for that time frame.
I am at a loss, this is a fresh OS install about a month ago on a brand new Samsung 840 SSD. All my drivers are up to date, I didn't have this issue a week ago but I did have a system restore point that I restored my computer to and that didn't fix it.
I also tried the Windows Startup Repair, and it tells me it could not repair it and to check my log at "F:/Window...." whereas I have NO F:/ drive and Windows is obviously installed on my C:/ drive (also, it will not allow me to "refresh" my computer. *I have legit Windows 8 Keys that I purchased
I have tried disabling the fast boot in power options.
I have ran a registry cleaner (ccleaner, I hate running cleaners but it was a desperate measure).
I tried creating a new user account.
I checked my Event Viewer and these are common errors I am seeing:
The driver DriverWudfRd failed to load for the device SWDWPDBUSENUM{69d0e255-85f2-11e3-be67-806e6f6e6963}#0000000000100000.

As my machine doesn't support SLAT in HyperV I am using VMlite XP mode to run some 16 bit programs I need. Very occaisionally VMlite hangs on close after it has saved state or shutdown the guest machine.
I go to task manager and click end task on the Workstation GUI and it closes but very occaisionally end task wont closed the program. Sign off wont close the program either and restarting hangs at the blue screen 'restarting' I have to push the reset button on the tower to get the machine to restart.
Is there any hidden way of closing VMlite so I dont have to restart, a sort of hard end task?

I have a very frustrating issue with Windows 8 where my software disappears when I select to open an existing file from within the parent program. It is not minimized and it is not 'off' the screen. I open task manager, and it doesn't exist as a process in any state. The program is Xilinx's ISE for programming FPGA boards.
Before, I get the obvious response that it is an issue with the ISE gui and not Windows 8, I've had a similar problem in another program in Windows 8 in which when I tried to create a new folder in a select file dialog box to save a file, the program would disappear. (Though, I don't recall which program that was.) It's as the program closes completely! (I'm lovin' Linux even more now.)

This is a problem i have been having (win8pro, amd 4850, whql drivers)...
When/if a full screen game or 3d stuff hangs up, on windows 7 you can open the task manager (by any means, ctrlshift esc, or ctrl alt sup, or alt tab and right click task bar)and end the process, but on windows 8 the games keeps some kind of lock on the desktop and i can't kill the process because i can't get focus on the task manager...
I can see the task bar, i can alt tab, and with alt tab i can see what's going on the rest of the windows, but i can't input anything on them, except on metro apps and start screen, so i can't access the task manager and kill the app.
When something like that happened on win 7, you could still open the task manager above the game and end it
I have to log off and log on in order to kill the application...

Running Win 8.1 on HP laptop.
Task Manager shows Disk at 100% but only a couple on tasks show any HDD activity.
I assume that there are hidden processing eating up my HDD (and CPU).
How do I see what else is running?

Recently Task Manager decides to crash on open.
After that these 2 entries are created in the Event Viewer:
Event ID: 1000, Source: Application Error
Code:
Faulting application name: taskmgr.exe, version: 6.2.9200.16384, time stamp: 0x50107c26
Faulting module name: taskmgr.exe, version: 6.2.9200.16384, time stamp: 0x50107c26
Exception code: 0xc0000005 Fault offset: 0x0000000000039924
[Code] .....
I suppose the second entry is sent by Error Reporting to MS? What is causing the crash?

Just found out that when I go to Startup items from Task manager and msconfig, Startup is not populated at all. All the items set to start are working and visible, just no listing in Startup for any. System scan including Dism comes up clean as a whistle and so is malware detection. Haven't checked since newest updates but can's see a reason for them to do only that.

I am currently using Windows 8 Professional (x64) as an administrator. My issue is that often certain programs or software do not exit properly and show up on Task manager as background processes. The issue is that I cannot end these processes because "Access is Denied" and must therefore restart my computer in order to run these programs. A simple example is Skype. When I quit Skype, it will show up as a background process on Task manager and I cannot end the process. If I try to sign into my Skype account again, it says that I am already logged in from this computer. Battlefield 4 is another example. I've never had this issue with Skype or BF4 previously, nor do I remember installing something significant that may have made changes to my PC.

I unlocked my AMD Phenom II X2 CPU to 4 core, but the Windows not show it. The Task Manager not show it and CPU-Z show only 2 cores. But the Device manager and a BIOS shows all the 4 cores.
I found this solution for the problem, but it is not working. When I do these steps the Windows restarts, but nothing happens. Maybe because I use a Windows 8 and a never version of EasyBCD.
What can I do for working 4 cores?
