Clean Install Win 8.1 - System Process Using Over 70% CPU
Feb 17, 2014
I 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 would like to nuke system for clean install. I understand there will be system reserved partitions, however, my main concern relates to OS and DATA partitions - Review attached screenshots :
150 GB for C (OS) drive?
30 GB for RECOVERY?
Remaining for DATA?
I am unsure where did I read RECOVERY should be the last partition - how would this be accomplished?

I have a Windows 8.1 Update 1 ISO and would like to use it to perform a clean install on a system which supports UEFI Secure Boot but has no optical drive. What would be the best way to approach this?
WIMBoot would be nice to have as well, if there's a way to do it without making things too complicated.

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.

I just got a new laptop, a Lenovo X230, for which I paid extra to have the OS on it as Windows 8 Pro.
So--now I have it, and Win 8 Pro 64 is installed and activated on it. I am a legal owner of Win 8 Pro.
However, I would like to do a clean install of Win 8 on the computer, to have it free of bloatware, etc. (In fact, I would like to set up a multi-boot with Win 7, and perhaps even triple boot with Xp as well. (I have installation media and my product keys for XP and 7 though, so those are not really a problem.)
The computer came with no discs at all. There is a procedure to make recovery disks. I may do that, but I think those will be to restore the computer to how it came from the factory, and therefore not usable for a clean install.
I don't see my product key for Win 8 anywhere. Not on the computer, not on any kind of card that came with it, etc.
I looked at the tutorial here for clean install of Windows 8, but it requires an install disc and product key. I have neither, although I am a legal owner of Windows 8.
Is there a way I can create (from my installed Windows 8) a win 8 install disk, that can be used for a clean install? Or a link to download one? Is there a way I can get my product key?

I'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.

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.

I 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.
Specs:
OS: Windows 8 Pro x64
CPU: core i3-2350M @ 2.3 GHz
RAM: 4 GB DDR3 @ 1333 MHz
HD: Samsung Spinpoint ST500LM012 HN-M500MBB 5400 RPM

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?

I tried restoring my computer using Easeus backup, but an error occurred during the restoration process. I've managed to fix it by doing diskpart /fixmbr and then using the windows dvd automated repair, however, what I ended up with is this:
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?

Recently bought a Dell Inspiron 14R 5437 laptop with Windows 8 SL (ES). Everything worked fine. Decided to get a Windows 8.1 SL (EN) version and did a clean install. After installing windows and successfully activating I started to install drivers from official dell site via wired internet. First downloaded Wifi/WLAN driver but it doesn't seem to install (Message displayed during instal: The installer can not run on this platform. Please select package for your operating system.)

I was trying to clean up my 8.1 system and encountered a folder that it won't allow me to delete or move. It is in C:users[me]appdatalocal emp and is named rarsfx4. It appears to have been used by my AV pgm., Bitdefender, at install time. When I attempt to delete it, it asks me if I want to move it to the recycle bin. I click Yes. Then it says I need to provide administrator permission to delete it. I click Continue. Then a little window pops up and quickly disappears that says '234 items recycled.' Then another window appears that says 'You require permission from xxxme to make changes to this folder' and gives me only the option to try again, which just repeats this last process. xxx is my PC name, and xxxme is my user profile name, not any user account name that shows up in Control Panel, User Accounts. (I have only one user account, which is a network one, my gmail ID.) When I check Properties, Security, for the folder, I see that System, my network user account (which is an administrator), and Administrators (xxxAdministrators) all have full control. When I click on Advanced under Security above, the owner is displayed as Administrators (xxxAdministrators).
I also tried deleting the folder using Command Prompt, Run as administrator, but get 'access denied' for every file.
My questions are what is going on here, and what can I do to remedy it?

I have recently purchased Windows 8 Pro Upgrade and for Christmas I will be getting my first SSD.
I want to do a clean install of 8.1 via USB, is this possible with the Windows 8 Pro Upgrade key? I have read through numerous tutorials and think I've got it right but just want some to clarify this will work.
Download the 8.1 ISO
Use the generic key to run the installer
Setup the PC
Open PC Settings
Change Product Key enter Win 8 Pro (upgrade) key and activate
Do I then need to do the reg edit and command prompt changes? Regedit - HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Setup/OOBE Command prompt - slmgr /rearm Do I have this right or am I missing something?

I have an upgrade key to Windows 8 that I bought to upgrade from 7. Now that Windows 8.1 is out, I would like to upgrade to Windows 8.1, but I want to do a CLEAN, REFORMATTED install.
How can I do this when I only possess the upgrade key to Windows 8.1.
I am sure many other people are interested in doing this as well.

I read about how to upgrade from 32 bit to 64 bit with clean install. I have a 32bit win7 on my desktop and a 64 bit Windows 8.1 on my laptop.
My question is can I use the Windows 8.1 laptop do download the upgrade assistant and get Windows 8 64 bit? I don't want to screw up my laptop especially cause it has an OEM Windows 8 that how to reinstall in case of OS breakdown.
In case this is not possible, is there any way to get a 64 bit Windows 8 upgrade downloaded without another 64 bit os already installed?

How windows 8 works now without the sticker key on new laptops. I've searched all over the internet and all I can find are dumb articles telling users to use the manufacturers recovery image. How to do a CLEAN install of Windows 8.
My new windows 8 has NO sticker key on the bottom so my understanding is that it's stored on the bios? Is this correct? So my question is, is if I get an ISO of windows 8 and install it, will it automatically recognize the key or is the key only set up to be recognized by the PC manufacturers crapware filled image?
ALSO, if thats the case, can I use a 3rd party product to pull my key and then use that with the clean ISO? Lastly, where can I download a clean ISO of windows 8? I know you can download official windows 7 ISO's, but i cannot seem to find an official windows 8 iso. I have no desire to download a torrent or from some shady website, I just want an official ISO.

Completed a clean instal of 8.1 on a OCZ Vertex 4 SSD but cannot write any files to program files X86 folder? I am being told access denied. I have tried looking into the permissions etc but it will not allow me change anything in the Security User Permissions or anywhere else. I am obviously set-up as Admin but cannot get anywhere with fixing this issue.

I purchased a Lenovo Y510P laptop over a month ago which came with Windows 8.0. and I hated it from the get go. I was aware that 8.1 was available as a free download so I downloaded and installed it. All of these updates seem to have bogged down my system. When I click on what I am assuming is the new start button (the white house icon in the taskbar) it takes 6-10 seconds for the menu to appear .
I dug out the key with Belarc advisor and went to MS's site to download an ISO of 8.1 but it told me that it would not let me download the 8.1 ISO since my key was for 8.0. If I were able to get my hands on a 8.1 disc would I be able to use my 8.0 key to do a clean install of 8.1? It is so disappointing to have purchased such a powerful laptop and have it bogged down by so many updates as well as all of the bloatware that came preinstalled on it.

I recently built together a brand new computer but after installing windows 8.1, the computer keeps BSODing with different error messages all the time. I've been trying to install my battlefield 4 but during installation, it will assuredly BSOD. It also BSODs when im transferring a large amount of files from my usb external hdd. Even in the process of trying to collect the minidumps and zipping the folder, it would also BSOD. I have already tried reinstalling windows but it has no effect.
My internet explorer also keeps not responding and while installing other programs they also "not responding"
Edit: after posting this, I was trying to install chrome from the internet but everytime I tried it kept BSODing, total of three times with each different error names
