command prompt and high cpu utilization problems

I have an Acer Aspire laptop. Windows 7-64 bit. My CPU usage has been quite erratic for months. She sometimes becomes up to 4 or 5%, but most of the time, he is running between 50 and 100% (I have a counter on my desk). I've been running all kinds of tools and cleaning methods. I had McAfee antivirus for a prior year of minimal, but renewed problems a few months ago and found strange and annoying that he wouldn't be updated every day while I was working. I assumed something was wrong with her, so I replaced it with a program that I got for free with another purchase from Best Buy... Trend Micro, I think it was called. Well, it appeared that Trend Micro used more process and CPU than McAfee. At that time, I thought it would be safer and cleaner for Microsoft Security Essentials TM trade. I also have CCleaner installed and I run it every other day or two. I also run r-kill and tdsskiller a few times but never found something dangerous. I removed everything that I felt uncomfortable unused programs were safe to remove. The last thing that I see and which seems odd to me is that, at startup, a "command prompt" icon will appear briefly in my taskbar and then quickly go to 'start' 'recent '... I have never seen this before so it seems weird, like a clue any. Also in the last few days, usually online, but also with Solitair Windows offline. Either the cursor will freeze or the screen freezes making useless cursor, even for a moment, and sometimes I'll just "end task." I'm not a gamer, I mainly watch movies and videos... Try, anyway! Thanks in advance for the help!


Wow you're gluten for punishment than TrendMicro Mcafee Ouch

You did use less uninstallation of Mcafee?

You can get trendmicro from Mcafee here too

Personally, I use Panda free and Premium of Malwarebytes.

  • Very high CPU utilization

    Hi all

    We have several standards work of the Disqualification created to standardize the data from the source systems. Among all, there are 2 positions causing the CPU usage greater than 97% throughout the work. For the jobs of rest with the same logic, but the source systems different data do not take this as the CPU usage.

    Run these 2 high CPU utilization causing positions for 50 k records and also around 1 lakh separately but still the CPU usage remains the same. that is more than 97%. Are there other specific job setting or settings that causes this problem? For the rest, the jobs CPU usage is average only 55%. Performance wise, it is not accepted and PT test sign off is blocked because of this.

    Appreciate your suggestions! @

    Thank you

    Amol 971-505343978


    Why do you think the high utilization of the processor is a bad thing? On the contrary, Disqualification treat this work as soon as possible. While other jobs [that run at 55%] are i/o bound and probably run a lot faster if you were to set the I/O bottleneck.

  • Satellite A300 DVD tray will not open and cause high CPU utilization peaks


    I have a laptop Toshiba Satellite A300 - 1 MM and I have a problem with the optical drive (Mat * un DVD Ram Uj880as):

Eject commands the position of work and management of the computer-> disk management will not work. I can open the tray manually but the optical drive will not read any cd/dvd. No error code in return.

    When that happens it cause peaks of high utilization of the processor (from 60 to 100%) in the System Idle Process. Just stop and restart it solve. After that, the laptop also runs fine and the optical drive.

    I replaced Win7 32-bit with a 64-bit version and the problem persist.

    Help, please. Thank you.

    I have the same machine with Win7 32 bit and use several players. Everything works perfectly. On this virtual path, it is not easy to say what may be the problem. The configuration of your laptop is not known to us, and we don t know how you set up your operating system and additional applications are preinstalled.

    Maybe stupid advice now, but you must install recovery image original Vista that you got with the functionality of your laptop and test with the factory settings. If the same problem occurs we can chat about it.

  • Problem with command prompt and installation


    I try to install Oracle Hyperion on windows server 2012 R2. I have the files downloaded on a single server. I traced this drive on another server. When I try to run the installation file "installtool.cmd" by right clicking and select "Run as Administrator", it does not start. I use a service account that has administrator rights and part of the local Administrators group on the server. However when I copied the files on the local disk, it starts. I have four servers in the deployment and I don't want to copy the binary files on all servers. Not sure why she does not launch when I launch from the mapped drive.

    The other problem is that when I try to launch the command prompt (Admin) and try to change the disc on the mapped drive, it does not change. It gives me this error.

    The system cannot find the drive specified.

    But when I use the normal command prompt, change the drive.

  • PowerShell has stopped the work and high CPU usage

    My laptop recently started to operate erratic, slow, very slow start as well as general use... even the cursor was glitch.

    A recurring error is "powershell has stopped working".  and "the security will not allow this download."

    I did a defrag and clean the c drive... I'm not very tech savvy, so I took it to Geek Squad, who said that they could not recreate the problems.

    They made an optimization, malware, cleaned and changed the browser...

    I opened the monitor cpu and the cpu running very high, sometimes 100%, and the laptop gets hot, even though I have a cooler under him.   If I disable the internet CPU breaks down... when I turn on the internet that it goes back immediately.   It all started around November 15 and I have no idea why.

    I am running windows 7 and have a HP Pavilion quad core with 6 GB.

    When I ran spybot there any spy software, but a huge amount of temporary files.

    The Geek Squad said it was a virus, but they had cleaned up a bit of malware.

    I have no idea what to do now?

  • transfer of samba and high CPU


    We make the transfer of files on SAMBA between 2 windows machine.  (a Windows XP and a Win Server 2003 SP2).
    There are 4 files transferred in parallel.
    The transfer rate is about 70 MB/sec.
    Immediately we see #4 to 20% CPU and the CPU continues to increase over time up to 100%, how much the machine hangs until we have stop the transfer on the source.
    Process Explorer means that the 'SYSTEM' process is consuming the CPU.
    Kernrate indicates threads are ntkrnla.exe and hal.  Seems to be the core partner.
    Is there a known issue connecting to samba?  How to twist Win2k3 to not die?

  • memory leak Winlogon.exe and high CPU usage

    I use Windows XP SP3. I'm leaking memory in winlogon.exe (about 5 M/hour). In addition, the CPU usage spikes to 50% of all 6 seconds. The file is properly signed so probably not a virus.

    This problem started after the application of last weeks patches.

    I seriously doubt that winlogon has a memory leak or people around the world would be screaming about it... and they are not.

    If this is what a thing look like, then you have another problem - probably a malware infection, or what you are currently using antivirus/antimalware protection is afflicted.

    Looking at previous answers, I would say that McAfee is afflicted, and it is already a well know that McAfee is a memory and CPU hog and you may want to consider replacing with something of less intrusive as Microsoft Security Essentials (do you use McAfee?).

    Since the Microsoft Answers forum does not have any kind of information system request when a new question is asked, we know absolutely nothing about your system.  Not knowing the basic information a problem prolongs the frustration and the agony of these issues.

    Thank you MS Answers, allowing the resolution of simple problems as frustrating and a lot of time as possible.

    Provide information on your system, the better you can:

    What is your system brand and model?

    What is your Version of XP and the Service Pack?

    What is your Internet browser and version?

    Describe your current antivirus and software anti malware situation: McAfee, Symantec, Norton, Spybot, AVG, Avira!, MSE, Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc..

    What do you see (exactly) that you don't think you should see, and when you see it?

    If the system works, what do you think might have changed since the last time it did not work properly?

    No matter what you use for malware protection, follow these steps:

    Download, install, update and do a full scan with these free malware detection programs at:
    Malwarebytes (MMFA):
    SUPERAntiSpyware: (SAS):

    They can be uninstalled later if you wish.

    The scans by operating clean, restart and fix any problems.

  • Desktop Windows 7 high CPU utilization

    I have a HP p6744y and for the last month the CPU worked 100% almost constantly. Read as many blogs ran so many viruses, malware and kill root programs without help. When I check treats all users, it lists svchost.exe sometimes ranked at 90 to the title using 7 236 k memory and local services. How can I make this stop before I kill this computer? I must say I think started after I installed an update of Java, could this be the cause?
