My process "System" which leads to C:WindowsSystem32 toskrnl.exe uses about 10 CPU all the time. I'm wondering what it does, and if there is a way to lower the usage.
View 2 RepliesI've been having some issues with the system process using around 10-20 percent of my cpu lately. I gather that the general solution is to find a problematic driver using kernrate and process explorer, but I can't seem to find a version of kernrate that will work on 64 bit machines.

View 9 Replies View RelatedI have a laptop running Windows 8 Pro x64, and lately I'm facing an issue where the System process (PID = 4) has spikes of 100% of disk usage according to task manager. I can't watch a video or play a song on a media player properly, for example (there's a crackling noise and the playback is slow), because this process (System) keeps using 99-100% of my hard drive.
Even if I have just booted up and running only the essential OS process and services and completely idle, task manager keeps reporting several spikes of 100% of disk usage. Tried uninstalling antivirus (avast free), but that didn't work. I really have no clue what do to prevent this process from writing/reading so much into HD and reaching 100% of disk usage.

I recently got my new computer and I'm a fresh user of Windows 8. I'm happy and all I was just wondering if the system interrupts process is a normal process, should it be there at all ? It does no harm so far (I think), I just wasn't sure after reading up on it if the complaints were only because the process was usually a high %, or if the process itself is bad.
View 1 Replies View RelatedI just did a clean install of Windows 8.1 Pro on my Lenovo Lynx tablet.
I noticed today that the tablet gets very hot even when the screen is off. I looked at the Task Manager and saw that the CPU is constantly at 99% and a process called "System" is hovering around 70 to 75%. When I run Process Explorer, the two threads using the most CPU in that process are labeled "ntoskrnl.exe!EtwProviderEnabled+ox6e".
Here are the ones I've tried:
Disable the scheduled task called "ConfigNotification" located in Task Scheduler Library > Microsoft > Windows > WindowsBackup. That task doesn't exist.Updated every driver that I could. No change.Waited. Over 12 hours and no change.Disabled Windows Defender. No change.Disabled Windows Search Indexer. No change.Disabled/Uninstalled all network drivers. No change.
The only things I've installed besides Windows and all its updates are Office 2013 and Malwarebyte's Anti-Malware. The last solution I've found is to reinstall Windows which I'd rather not do .
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?
By chance, in Windows 8, there are some registry keys and entries that allow to customize the winlogon process during the logoff of the users sessions and during the system restart or shutdown?

So there are now two visible drives on my PC - C and Q (system reserved), and it doesn't see the data drive.
What I want to do is to make the data drive visible, and merge the C and Q drives into one (or make Q invisible), if that is possible. So, how do I do that?
when i leave my system in idle for an hour or two, it reboots without any BSOD, or any error messages. My rig is 5 year-old, and always worked perfectly with Windows 7, without any strange issues.
When i'm working, Win 8.1 works absolutely perfect for long long hours.. rendering video, playing games etc.. i never found a BSOD or random reboot.I did the following to try to solve this problem, without success:
- Changing my PSU.
- Changing the Win 8 energy plan to Maximum Performance (hard disks never turn off)
- Memtest for 16+ hours, without any error.
My guess is there are some Windows 8.1 feature that doesn't fit well with my mobo, but i can't find it. I have also the same version of Win 8.1 installed in another older rig, and works 100% perfect during days (working and idle).This is my problematic rig:
Gigabyte P55-A UD6, BIOS F12c Beta (the last available from Gigabyte)
G-Skill Ripjaws DDR3 2000 8Gb (2x4Gb)
Intel Core i7 860 Lynnfield
Sapphire Radeon HD 7950 3GB GDDR5
Corsair Force 3 180 Gb (firmware updated)

View 3 Replies View RelatedWindows 8 boots up pretty quickly, but it takes a notably long time (compare to Windows 7) for it to show up the system tray applications. In Windows 7 it is almost instant.
Is this Microsoft's problem or the app maker's problem?
Also, the apps seem to load sequentially. Is there a way to rearrange them so that the ones I want load quickly. I need AutoHotKey, Logitech Setpoint and Logitech Gaming Software to load up ASAP. Rest can take their sweet time.
Also this is what the TaskManager's startup performance analysis looks like.
Having this *feature* means that Microsoft can blame the app maker for the slow startup. But why doesn't that happen in Windows 7? Is this because Desktop is another app, and stuff don't really get priority?
Also I still cannot find why PeerBlock would not start when placed in the classic Startup folder.
Been running the upgrade to 8.1 from a factory installed Win 8 system on my Dell 5720 laptop. Download took quite long and now installation is taking even longer. It went through multiple steps on the Dell logo splash screen starting with "Getting Ready". Then it went to "Setting Up". Another lengthy time period. Now its doing "Setting up a few more things" and has been hung at 28% for over an hour. Hard drive activity very low and sporadic.
View 14 Replies View RelatedWindows 8.1 ... Noticed shortly after upgrading the Asus VivoTab Smart to Windows 8.1 (from Windows 8) -- that sometimes the system's date and time will be incorrect after a shut-down, turn on cycle. Sometimes the clock is as fast as three hours, but others much longer. Interestingly, if you go into PC Settings > Time & Settings and then toggle off the "Set time automatically" option, and then toggle it back on, the time and date are immediately corrected. However, the time would again be wrong after a shutdown. If the tablet is restarted, though, the time is correct again.
THE SYSTEM: Windows 8.1 (upgraded from Windows Store). Intel Atom processor.
WHAT'S BEEN TRIED: I:
1. Stopped the Windows Time service, registered it again and restated it. The issue remained. I entered the desktop and clicked on the time in the lower right-hand corner of the screen. From here I confirmed the time zone was correct and changed the date and time. That fixes the problem during the current session, but the time/date are again wrong on reboot.
2. Tried Safe Mode. In Safe Mode, the time is correct and stays correct.
3. Tried Clean Boot. In Clean Boot, with all non-Microsoft services disables, the issue returns and the time is wrong again.
THE BREAKTHROUGH THAT BEGS FOR AN ANSWER: While reading this thread, I read up on Windows 8's Fast Startup. Just on a lark, I went into the Power settings area of the Control Panel and turned off Fast Startup. Now the clock is correct. There's a downside , of course, to this in that shutdown and startup is notably slower.
The tablet now keeps perfect time -- but cannot have Fast Startup - which is a bummer for a tablet.
QUESTIONS:
1. Is this is hardware issue? Asus is offering an RMA -- but hate to add to a landfill when this is fixable with software.
2. Is there a way to check the BIOS clock on a Windows 8.1 tablet ? I believe it's a UEFI system....
3. Is there a way to fix this so fast startup can be used -- and have correct time?
4. Is this a known issue?
5. Is there a way to make sure the Windows Time service is activated in a Fast Startup.
I have installed the newest web browsers: Opera, Firefox and IE. I have the lastest version of Adobe Flash Player. When I want to watch any video on Youtube - it's almost impossible, cause it jams.

View 9 Replies View RelatedI am using windows 8 and from time to time the whole laptop freezes with only short moments where you can move the mouse until it freezes again.

After making clean install of Windows 8.1 (before I had Windows 8) then my laptop started to hang from time to time.
Selecting tiles in Start screen with keyboard is normal as it used to be , mouse moves normally but HDD light is not on or blinking. Clicking with mouse does do nothing.
When I click fast many times then it finally opens App from Start screen on a program in Desktop mode but everything is slow for 3-4 min. Then it automatically works as it should be, like nothing would be wrong.

So, I am trying to upgrade from windows 7 to 8 and everytime i begin the download it starts to go and makes it past the preparing which i see a lot of people having problems with. then it gets to the installation part and freezes at 11%. i left it to install last night as i went to bed woke up the next morning and it was still at 11% so, i decided to restart it maybe something was wrong, still nothing. Then i said to myself maybe if i start the disc from the startup screen it will work. Nope. When i did that it told me the installation process had already been started and i needed to remove the disc start up my computer normally and continue from there the way i was before.

In Windows 8.1, Modern UI app processes continue to run after I've closed the actual apps. I don't know if this behavior is intentional or not, nor do I know of any way to prevent it. I know in Windows 8.0, just about all apps stopped their processes after you close them. So why the persistence now in Windows 8.1? Caching/speed improvement? Is this unique to my system or is there a setting that can stop this behavior? I'd test part of this myself, except I don't currently have access to my other systems at home.

I don't have a Microsoft account, I don't want one. My Windows 8 E-Mail address is for the E-Mail account on the family webserver, and yet when I get the confirmation E-Mail, it links me to a hotmail/outlook login page.

I'm currently running Windows 8.1 and recently I took a look at my Resource Monitor and noticed a process called numbers.exe with the description "Numbers". It showed it as running in the background but in a suspended state. As I've never seen that process before, I decided to search it up and it came up with some results related to a trojan / rootkit. But this trojan / rootkit was namely referred to as <random numbers>.exe (for example 123456789.exe); nothing indicating specifically the process "numbers.exe".
I did a bit of digging in the associated handles and noticed that some of the files were related to the default Windows Calculator App, which I have currently pinned to my Start. When I unpinned it from the Start the process was gone. so I'm assuming it is the process for the calculator. But because of a trojan incident I had a few years back, I'm a bit paranoid based of the searches that popped up for numbers.exe. So this "numbers.exe" is a legitimate process? Who also has the default calculator pinned to their start have this process running as "suspended"?

My Toshiba laptop with Windows 8 won't run unless it's in Safe Mode. I don't know exactly how or when it started, but it completely freezes shortly after boot. Exactly when it freezes varies, but it's usually within the first 5 minutes. And by freezing, I mean it's 100% nonfunctional. The only way to shut down is by removing the battery, so now I just keep it out.
At this point I won't list all the things I've tried, or tell you all about my computer and OS. The crashing happens in a variety of ways, but the end result is always the same. I will hear a click sound through the speakers and simultaneously see a flicker on the display. At that point I will instantly know I'm screwed. Then within 1 to 5 seconds the HDD light on the computer will stop blinking and stay on solid, and my only choice is to unplug the power. It usually happens in one of the following ways, listed in order of likelihood, with the most likely first:
1) I get the BSOD with the error, CRITICAL_PROCESS_DIED.
2) My display freaks out, and turns into a jumbled up screen of glorious animated visual static. (I have a picture on my phone, if it comes to that.)
3) I get the BSOD with the error, REFERENCE_BY_POINTER.
4) No apparent crash, but one keystroke or mouse click will take 20 to 30 minutes to be carried out. During this time, Task Manager says HDD is working at 99 or 100%, even though the computer is idle. Sometimes I'm able to move the mouse pointer, other times I'm not.
5) I get the BSOD, with an error that I can't really make out. If I was forced to guess, I'd say it looked something like "x0x000000x".
6) I get a blue screen with a message telling me the computer was improperly shut down, and needs to restart after it collects data. Along with this is a progress report that never moves from 0%.
The last thing I tried was to reinstall Windows, keeping nothing. Now it seems my only available choice is to go through the hundreds of processes and services individually, turning them on and off, one at a time until I find the culprit, the way I had to individually download all of the 107 updates required in order for me to attempt upgrading to Windows 8.1 (unsuccessfully). The stuff I found in the Event Viewer didn't really seem to work, but I'll probably go back to it and research events more thoroughly before I start disabling things. I hope to avoid this.
I don't know if this is a clue or not, but in Device Manager my Generic PnP Monitor has an exclamation point by it, but Windows says the driver is up to date, and I can't figure out why why I'm getting the alarm.
When loading windows 8 pro the process appears to hang up about half way through - updates and features... The mouse moves and you can cancel , however the cancel never finishes... I' have disconnected all peripherals and obtain the same result.
