    Hello

    I think this explains the problem.  The 2 entries here should be deleted, because the first will try to index all of your user profile and the second will attempt to index all of the Windows Partition.

    C:\Users\Rick

    C:\

    To remove them, click to the left of the entrance, highlight it, and then click Remove.  When these two entries have been removed, reboot the laptop and you should find that the problem has been resolved.

  • Explorer.exe uses too much CPU

    My explorer.exe uses too much CPU (almost 100%). Then an error message appears-

    Microsoft Visual C++ Runtime Library
    This application has requested the execution to terminate in an unusual way.
    For more information, contact the application support team.
    If I click on OK, or simply close the dialog box explorer.exe ends and restarts. After awhile, it starts to use full CPU again, and the same dialog box appears again. I have installed new software and tried almost every other way, this forum as restart explorer.exe etc...

  • Free version of 5.5 (CPU and memory limits)

    Hello

    Is there a limit CPU and memory if I run the free version of 5.5?  I remember that there is a limitation of a socket (CPU), but am not sure, maybe it was the old version.

    Thanks in advance.

    TT

    If I'm mistaken, the only limitation with the free 5.5 ESXi hypervisor is the 8 vCPU maximum of VMS and the restrictions for hardware virtual version 9 (5.1 compatibility) with the vSphere Client. Previous versions had all kinds of different limitations, like carrots by socket, physical memory,..., but that all left with the current version.

  • Settings of CPU and memory of reserve on the virtual machine running...

    Hello.

    I have two virtual machines in production with CPU and memory settings of reservation applied as shown below. I want to adjust these settings of reservation to "zero" for the CPU and memory on both virtual machines.

    I can make these adjustments while VMS are running, or do I need to power their first?

    Any advice would be appreciated.

    Thank you!

  • -Plug hot CPU and memory

    Hello.

    I'll try the new features of vSphere and have a double with the addition of a CPU or memory to a virtual machine while it is running.

    First of all, Microsoft said that only the data center itanium editions and supports the addition of hot CPU, but I found some forums who say they did the test with other editions as standard or enterprice, is this posible?

    http://www.Microsoft.com/windowsserver2008/en/us/R2-compare-specs.aspx

    http://www.Microsoft.com/windowsserver2003/evaluation/features/comparefeatures.mspx

    I tried with a windows server 2008 standard x 64 and when I added a CPU Device Manager shows me 2 CPUs, but the Task Manager doesn't show one and when I added to that memory, the Task Manager shows no change, but Device Manager shows the new memory module with an alert.

    When I restart the virtual machine to the new hardware configuration worked well.

    If windows does not support hot branch of CPU and memory in the data center and itanium editions, why is the option available (when we edit a virtual machine) for other editions as standard?

    Thank you...

    Here is a good list which has been implemented and seems to be fairly well validated.  But the result is, it has windows and a restart could never hurt.

    Hi team,

    In one of our Production Server is a process called "svctimesag.exe" using high CPU. This problem has been detected the day before.

    For immediate solution, we killed the process, but it did not help, then you need to restart our server.

    In the past 24 hours this process has shoot to the top of the CPU twice and you need to restart the server with force.

    Also searched the Internet but found no information. The location of the file on the server is C:\Program Files (x86)\Products\svctimesag\svctimesag.exe

    We organize engine on the server management application. We also opened the case with them to know the process.

    If any user face any problem with that part of process please your valuable troubleshooting strike.

    Thanks in advance.

  • Explorer.exe takes 100% of CPU

    Hello

    I have Windows Vista 32 Bit laptop computers of company with the following features:
    Core2Duo 2.0 Ghz
    2 GB OF RAM
    HARD drive of 160 GB (two equal respectively to 27, with 25 GB of free space on partitions C & D)
    256 MB ATI graphics card
    I have automatic updates of Windows, so my version is up-to-date. I use NOD 32 Antivirus (latest virus definitions)
    Since the last two days I noticed that my CPU usage is costantly 100% (even when the system is idle) and explorer.exe takes up most of the CPU (95-98%). So my laptop started running hot with the processor fans works at high speed. I have not installed new software recently. Can someone help me with the problem and bring down my CPU usage. I tried to change the parameters of the START property search (someone posted this solution on another forum), but with no improvement.

    Hello Design_engg,

    Try to start your system in safe mode:

    1. Restart your computer if it is running.
    2. Press and hold the F8 key for 3 seconds after your computer powers initially on.
    3. Once you see the menu Options advanced boot (or you hear a beep) you can stop.
    4. Up/down arrow keys to highlight your selection.
    5. Select Mode safe mode with networking and press ENTER.
    6. You should see drivers loading, it may take a few moments.
    7. You should then be at the Welcome screen.
    8. Connect to your computer using an account with administrator privileges.
    9. Now, you download (free) MalwareBytes from here: http://download.cnet.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html?tag=mncol install, Update then do a scan of your system in safe mode, to ensure that it is indeed clean! Once the scan done remove anything it finds. Simply restart your PC to see if your problem has been resolved!

      Hope this helps you. Let us know anyway. Make it a great day!

  • High CPU and RAM usage - laptop Dell w / Vista

    Hello

    I have read several posts and tried many suggested fixes, but none seems to work so far.

    Hardware: Dell Inspiron 1525, with 3G of RAM

    Operating system: Vista Home Edition Premium, SP2

    Problem: CPU high (~ 50%) and RAM usage (~ 50%) when ideling.  I did both a "clean boot" and boot into "Safe Mode with network" and neither seemed to make much difference and certainly has not resolved the problem.

    When I go to the 'task manager' is a process "svchost.exe" system which is the eater of resources.  I can move the tab "services", but I'm not really sure how to use the information presented.  This is where I'm stuck, as I said, I read a few other posts with similar (but not identical/software) and I've tried a few things but do not seem to be able to solve the problem.  Please let me know what the next logical steps are at this address.  Thank you.

  • High CPU and disk utilization slows down the response

    Two years, Pavilion dv7 - 2273ca running Windows 7 64-bit; Norton 360; IE8; Thunderbird; Microsoft Office 2007.  Tend to have several windows open at the same time.  For automatic updates

    Almost every day the laptop enters a period of very high CPU usage; often accompanied by high disk usage.  The response time of the laptop is compromised to the point that I often have to stop using it until activity slows.  I try to use the resource monitor, but do not know enough to say if the legitimate operations or something wrong.  Norton frequently shows svchost.exe and iexplore.exe as a heavy user of the CPU.

    Is this a normal behavior?  If not - any advice on how to identify the culprit?

    On the advice of a HP technician, I ran check disk, and then restore the system in August.  end hard drive.  System Restore did not difference in performance.

    Most of the processor have more of the base, there will be a CPU 0 and 1 for the dual core processors. Different colors are different carrots 0 and 1

    If you sort as I proposed that the highest CPU usage will float to the top, you have to watch it when your cpu pork starts to act up.

    The colors of disc are reading and writing, its hard disk is read or write data on the trays.

    A high utilization of the processor or disk can be considered normal at times, but should not go on constantly.and by dragging down the performance of the system

    Lets say you run a video in your browser, the CPU usage rises, running other programs can do the same thing.

    The disk activity can be high at times also, depends on what you do on the PC, but shouldn't be high all the time.
