• Windows 7 update - slow download, svchost high CPU usage

  I have a problem downloading by using the Windows Update application. This problem started after January 2016.  In the past, the request of update seems to work without the use of the svchost high CPU and with a reasonable download time.  There is usually a delay until the download has started, but then they ended quickly.

  I have 4 computers: 3 running Windows 7 Pro (CPU - Intel dual, i5 & i7) and 1 running Windows 7 Home (Intel i3).  If the problem is not related to the CPU hardware as best I can tell.

  My update setting is 'check for updates but let me download and install ".

  The Windows Update process includes 3 steps:
  1. identify the important and recommended updates for your computer.
  2. the selection and download updates.
  3. the creation of the restore point and of the installation, the selected updates.

  My problem is step 2, download the selected updates.  This happens on all 4 systems, and I do not expect a download to be this CPU load.  The download time is too long on all systems 4.

  My online search for answers has been frustrating, but several posts said search for viruses, malware and Trojans.  I ran Malwarebytes (free), Windows Defender, Norton Security and ESET (online) on systems and no objects are found.

  My most recent experience involved my Lenovo 7847 system (Intel dual core). Monday, May 23, I checked the updates and there were 15 updates important and 3 optional updates listed.

  After reviewing the updates, I chose the 15 updates and started the download process.  The svchost.exe that is associated with the update happened to 45-60% CPU usage, update status showed no size or % finished and the task manager - network or explore the process did not show any activity download for a long time.

  Finally, after about an hour, the update showed the download size and the % downloaded.  Svchost usage remains high during the time of whole download.  Once the download is complete, the restore point was created and updates have been installed, who also took some time (but it would be I/O CPU & Drive dependent).

  The download status has not changed during most of the time that the download process is running.  The Task Manager and process explore both show very little network activity up to that very near the end of the download procedure. There is therefore no real indication that the process is blocked or just turn very slowly.   It almost seems that the Microsoft servers are overloaded, they delay the download for some reason, or the process svchost and sub-process fail to create good handshake with the server for download.

  My Questions:

  1. Why is svchost usage so high when nothing seems to happen?
  2. Why does take an hour or more to download the updates?  These aren't the huge file sizes, and this attempt to update was almost 2 weeks after Patch Tuesday, then Microsoft servers should not be overloaded.
  3. Why is the situation unchanged for so long during the download process?
  4. most important, what can I do to change this situation?
   
  Thanks in advance for your help.

  My 'update problem' seems to have changed.  Checking updates takes a lot of CPU resources and a lot of time.

  We will leave well enough alone for now. [It took 3-4 hours for MU download/install updates of June on my Win7 boxes].

  But please bookmark this thread. If the behavior persists in July - and especially in August, respond to this thread instead of starting a new. Good luck!

• Windows Vista High CPU usage

  Everytime I open Windows Media Player and Internet Explorer, the CPU usage goes to 95% to 100%. Windows Media Player also responds to slow down even if it's the only program that is open.

  The problem started when I installed McAfee Internet Security and what Vaio Media settings have been configured.

  Please help how to solve this problem.

  Thank you.

• The CPU usage goes to 100%

  I have a laptop Dell Studio 2010, the processor Intel, 4 GB of ram, hard disk 320 GM (180 GB consumed) running Windows 7 and IE 11 giving me CPU usage problems.  I don't know what everything is related, so here's the story.

  I lived my download speed slow - dropped by half every 2 hours or more after a reboot.  Occasional problems with the speed of the computer as well, and when I checked the resource monitor I see the CPU usage hit 100%.  A reboot has always solved the problem.  Running in Mode safe mode eliminates the loss of download speed so I knew it wasn't a problem with the hardware or my cable modem or a wireless router.  I have explored many possible problems, but none solves the problem, then I reinstalled Win 7 Friday, January 16.  Download speed, not only fixed but faster than before.  It remains stable and do not disintegrate so there was something wrong with the OS, etc.

  However, the problem of the use of the CPU remains.  What seems to happen is that something triggers a high demand and then all processes on the computer joins.   When I look at the resource now monitor consumes 1.3% of CPU, but when things are choking it consumes 15% of CPU and go all processes running as 0.5% to 5%.  So you can't point to a single process as the culprit it is possible that web sites of strong demand (lots of ads) trigger the problem.  I'll do some research on that.

  I did a lot of web research as well as this forum, and no patches seem to work or apply to me.  I ran a Malwarebytes scan and a full virus scan with Microsoft Security Essentials: nothing found.

  The computer is almost 4 years, but I wouldn't spend the $$ to replace and find that the problem is software.  Any ideas?

  The problem solved when I've upgraded to Win10 on this machine.  At the same time degradation download speed (with time) newsletter is resolved.  I can't imagine how everything worked but I discussed the idea with several IT people I know and have gotten various suggestions.

  Since a clean installation of the operating system has not fixed it, I do not understand why install Win10 fixed, but that's it.

  Since then, I've replaced this computer.

• Why did FireFox flash black and then cause a huge CPU usage and crash?

• DAQmx read results 2 ms/s in high CPU usage

  I have an application that reads the 32 channels of 2 ms/s analog input signals, at the same time. The actual hardware will be: SMU-8135 Win7, chassis SMU-1071, 2 x SMU-6368 (16 channels). The SMU-two 6368 will provide 32 channels data acquisition.

  I don't have the material at the moment, but I've been estimate the processor on the alternative configurations needs, because I have concerns about the use of the CPU to data acquisition high speed. Two alternative configurations are:

  (1) SMU-8133 (quad core) WinXP, SMU-1062 q, PXI-6133.

  (2) PXI-8106 (dual-core) WinXP, PXI-6133, PXI-1042.

  Note: PXI-6133 supports high speed HAVE 2 ms/s, at the same time.

  I wrote a simple continuous data acquisition software to allow me to compare the CPU usage. The sample rate and the number of channels are configurable. What I found is:

  (1) at low sampling frequency, for example 100 kech. / s, the CPU usage is minimal on both configurations (bicoeur or image), regardless of the number of channels is 1 or 8. The reading of the CPU was about 1-4%

  (2) at high sampling frequency, for example 2 ms/s, what is the number of channels used, either 1 or 8, the CPU utilization was 50% for dual core and 25% for the quad core, IE. a full core has been fully utilized.

  (3) the passage of the low use of the processor (<5%) to="" high="" cpu="" usage="" (="">45%) increases when the sampling rate is rather steep and shows interesting channel-dependence (note the following has been achieved with a PXI-8106 controller, dual-core).

  • @1 channel, it happened between 950 to 970 k
  • @2 channels, it happened between 470 to 480 k
  • @4 channels, it happened between 230 to 240 k,.
  • @8 channels, it happened between 120 to 130 k.

  This model reminds me of buffer length related question but I double checked a sufficient length of the buffer was used. He suggested also, surprising a few traffic jams occurred when the amount of data increases up to certain level.

  My question is, is this a problem with this particular card (PXI-6133) or driver DAQmx (9.5.5f4). How the problem is when I'm doing an acquisition of 32 channels?

  For your information, I have attached the benchmarking software.

  Thank you!

  Donghui Yin

  I followed this example code (see link below) and used based on events DAQmx, now the excessive CPU utilization problem has been resolved. Playback from the CPU is now less than 10 percent, while it could be 50% (in the case of dual-core) or 25% (case of hearts) at the same sample rate and number of channels.

• Svchost.exe causing 100% cpu usage during the update of windows, even when disconnected.

  I recently had to re - install windows xp on a new hard drive for replacement. My version of xp home edition, SP2 OEM installation disc. (This is ith group included IE6)

  Once installed and running, could access windows update.

  Read all the threads associated etc. and installed SP3, disc after downloading microsoft on another pc. Installed after three trys, first two caused various mistakes, but third attempt seems OK!

  I've also updated the IE6 to IE8, as some sites obviously did not work properly with the older browser.

  Now go do the automatic updates, or log for manual updates... BUT!

  During the process, my cpu fan comes on fast and permanently! The CPU usage is showing that 100%, pc slows to crawl, the mouse becomes slow etc.

  This has never happened before on this machine before you reinstall clean, he had already automatically updated to SP3 and went very well, it was some time ago, before the failure of hard drive, and it has never had this problem!

  Only since having to do a cleaning manual update and re - install.

  The culprit seems to be svchost.exe, once it is used by the update, running the cpu at 100% and continues to do so EVEN after stopping the service, until I manually stop with the Task Manager!

  The svchost.exe instance showing a high is use: SYSTEM.

  According to the files of help here, it is a known issue and a fix KB927891 was issued for SP2, but this should NOT be necessary for SP3, and in fact difficulty used to perform anyway under SP3!

  Ideas for a guy to fix?

  I appreciate the support for XP runs out quickly, and after this update of windows will be redundant, but in the meantime it is always useful!

  Also if I turn off the automatic updates, how can I stop this annoying popup warning bubble?... I can't live without updating, but this bubble nag drives you nuts! :)

  OK just a update, now running cool and 100% auto update and manual update... How? I hear you ask...

  Well I had a beer and a reflection and came to the conclusion, it must be 'order' in which I updated the clean installation of XP.

  Origin, I loaded the old OEM disc new hard disk, loaded the drivers etc, then stop at windows update for updated files.

  Who told me my old incompatible browser and suggested an upgrade.

  I downloaded and installed IE8... still no joy, reading the forums comments I downloaded and installed SP3... which SEEMED to work, BUT then all the hassle of cpu to 100% with the automatic update and updated manual on the windows don't update site!

  So I just gritted my teeth, formatted the drive, another OEM of XP Home Edition SP2 installation loaded the drivers, installed a copy saved to SP3 and after restarting, THEN installed a saved copy of IE8 and THEN trotted off the coast to the windows update site... low and behold, it the connection without problem, did a search, and required updates appeared on the screen without delay all 123 of them...! :)

  Did the updates, restarted and everything was fine, updates automatic in market and left the machine, after about 30 minutes appears the yellow shield, and it downloads a couple more update files without problem.

  All this time I followed the via the Task Manager CPU usage and the strange spike waited 100% apartment, it was on average from 5 to 20%!...so a great improvement has this effect, by simply changing the order of the updates installed from the original! SP3 IE before IE8.

  May not work for all have to do a clean install because of the HD failed, but its worked for me, and I am once more a "happy bunny!

• The CPU usage reaches 100% and the system locks requiring a hard restart on Windows Vista

  All of sudden the CPU usage reaches 100%, which makes the system dead slow and finally the system stops responding. I have to do a hard reboot to continue using the system.

  I tried to open the Task Manager to see if there are programs or services running that can consume resources and found nothing. The remains of number of CPU use, the graph to use but less than 10 years is hovering at 100%.

  I did not change my system.

  The problem appears on the two accounts that I installed on my operating system.

  I removed all the unwanted programs since the system was started.

  I have McAfee Antivirus installed for more than a year now, and the latest antivirus patches have been installed.

  Help, please.

  Thank you in advance!

  Vista and Windows 7 updated drivers love then here's how update the most important.

  This is my generic how updates of appropriate driver:

  This utility, it is easy see which versions are loaded:

  -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
  For each driver in the list, additional useful information is displayed: load address of the driver,
  Description, version, product name, company that created the driver and more.
  http://www.NirSoft.NET/utils/DriverView.html

  For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
  Control Panel - device - Graphics Manager - note the brand and complete model
  your video card - double - tab of the driver - write version information. Now, click on update
  Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
  Uninstall - REBOOT it will refresh the driver stack.

  Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
  with their own software and drivers and all other main drivers that you have.

  Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
  Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
  BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

  Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
  each installation.

  Always check in the Device Manager - drivers tab to be sure the version you actually install
  presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
  in particular that) so to install a driver - reboot - check that it is installed and repeat as
  necessary.

  Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
  manually by model.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

• Satellite C670D-10W - Task Manager shows 100% CPU usage

  My new laptop with windows 7 factory-installed and all programs by Toshiba nothing addded present 100% of the CPU usage in the task Manager and works quite slow. The sum of 80 strange process in the Task Manager is never more than 30 to 50%, but the key is always 100%.

  Process hacker I tried 2, shows the same process in Task Manager.
  What can be the problem?

  Hey Malki,

  He run a background process and they need the CPU usage that of normal. Antivirus is running in the background like other tools as well. As far as I know after the installation of recovery the defragmentation tool runs also in the background.

  Interesting to know is what problem you have. I mean usually the CPU usage is not important if you can do everything and computer works correctly.

  You have problems?

• Satellite A40-231 - 100% CPU usage when any browser works

  Hello
  my laptop is satellite A40-231, I have a problem for days.

  When I open any browser (I tried firefox, IE and chrome) I can't watch the video, everything is slowing down, I can't navigate between pages.

  I took a quick glance to the use of the cpu and it increase to 100%, it never decreases. When I close the browser, the CPU usage drops to 15%, which is normal. I thought it might be a virus that internet connection and make things slower. That's why I format my laptop. I deleted all of my hard drive and reformatted. I installed Windows again, but he has not changed. I even installed ubuntu (I thought maybe virus can not work under ubuntu), but it's the same thing. I turn on my laptop and I open a browser and the laptop slows. I have clean the cpu fan it has not helped.

  I tried to solve it for days I could not sleep properly, I'm about to cry :(

  Please help me please.

  Hello

  You have reinstalled Windows using the Toshiba Recovery disk? This drive will restore the settings from the factory with all the drivers and tools so everything should work fine after that.

  In addition this happens with LAN or WLAN connection? You should try it with the other connection.
  Also check your router and update the firmware. Try to disable the encryption, MAC address filtering, etc.

• Portege R100 - CPU usage 100%

  Hello!

  Everyone knows about this problem?
  My Portege R100 after installing the new copy of Windows XP and directly after the installation of the display driver, Trident (reboot) bizarre behavior.

  Welcome screen goes white on the lower part (when the first yellow line is). Then I have some software problems.

  When to start records search engine, when I update the list of wireless networks and I explore the files by clicking on 'My computer', (this does not happen when I right click on START and 'Explore') displays CPU usage 100% and everything is so slow that I can barely move a cursor.

  Everything goes back to normal once I closed above applications.
  I can install all drivers and all right, but after Trident display it is bad.

  This is the driver I use since I bought the laptop, I do not know that is fine.
  I installed it several times before and I have a few copies of it, which I've already tried so it must be good.

  The cross thing only my mind is a hardware failure.
  Someone of you knows than before?

  Thank you...

  It has nothing to do with your computer - this is the trident driver problem - there is a work - around
  Try changing your display configuration-

  (1) right click on your mouse to the desktop to bring up the display property, and then click Advanced - here, you will see a tab say somethng like 'graphic acceleration.
  (2) reduce the rate of acceleration - move the tab to the left - make sure it is not full
  (3) this trident driver can cause the BONE to redraw the screen whenever you move your mouse with some applications

  If my post is not detail for you
  Try google with the keyword "how to turn off the graphics acceleration in windows xp" - you will get some good instructions

  That will solve your problem!

  Good luck and enjoy your nice laptop!

• Why my svchost.exe process constantly runs at 100% CPU usage?

  Recently, my computer was extremely slow.  I thought that was the cause of a worm or virus but after I used Norton to take care of that my system is still slow right too. When I checked my system process, its display svchost.exe using a massive amount of memory. Therefore, my CPU usage is constantly at 100%.  Is it still the result of a bug? Or do I have to look elsewhere as the source of the problem? Thank you

  It is possible that a recent update of Norton was faulty or caused one conflict with another program on the PC.

  Activity excessive svchost.exe is often linked to one of the following:

  1 resource hog like Norton or McAfee (sad but true)

  2 be linked in Microsoft Update instead of Windows Update

  3. after having been updated for Windows Search 4.0 and its endless reindexing

  4. the presence of malware

  Unless you have uninstalled Norton AND used their removal tool, I doubt you really deleted ALL occurrences of Norton!

  FWIW, I helped a neighbor recently with his performance problem. The culprit in his case was Windws Search 4.0. And since there is no entry in the Control Panel Add / Remove programs to KB940157, I needed to follow the instructions offered by Nepatsfan here:
