Running On Explorer.exe While Memory Usage Jumps Up
May 28, 2008
When using any icons view in explorer.exe with a folder containing MPEG-2 video clips, and/or having the details pane switched on for such folder, explorer.exe eventually uses up all available memory until windows fail to redraw. Restarting explorer.exe or the computer temporarily fixes this problem until all memory is used up again. The problem can be reproduced with folders containing MPEG-2 clips. Other file types do not seem to trigger this behaviour. The process running on explorer.exe while memory usage jumps up is the following: RunDLL32.exe "C:Program FilesMovie, Makerwmm2clip.dll",VMGShellThumbnailGenerator "{FileName}.mpg" 256 256 0,Is there a known fix or workaround?

I have a Toshiba notebook with Vista Business installed. Recently I installed the sidebar and added the "CPU performance meter" and noticed that it was constantly in motion. Looking at the Performance tab in task manager, I see that the CPU(s) (dual core) are very priodically show spikes. Every 4 to 5 seconds, the usage jumps from perhaps 10% to 70-80 %, and then goes back to 10%.
The laptop shows this bahavior over long periods of time, even if no application is running. Looking at the processe that are running, it appears that one of the "svchost.exe" (of which there are quite a few) seems to be the culprit, but I have no idea what is behind it. How do I find out what this process is actually doing? Can I simply end it to see what happens, or will that harm my laptop?

This has been going on for quite a while but its getting to severe points. What's happening is basically explorer.exe jumps straight to 95-99% when vista boots and remains like that without budging, resulting in extreme slow computer performance. Attempting to close the explorer then restarting will temporary bring it back to aroung 50% but it will soon jump up again, restarting doesnt work.
Here's the stuff Ive tried to do:
1- Got rid of the index.dat files in the TIF, apparently they slow performance.
2- Turned off search indexing
3- Tried to defragment the memory, but it doesnt do anything!
The weird thing is that it jumps to 99 without having anything running which implies that there is a background process thats eating up the CPU!

I've had Windows Vista Ultimate for a while, and recently I've been noticing that the pc is using a large amount of memory. While playing World of Warcraft, it sits on 1.5 GB of ram out of 2GB, and everything slows right down. I also have 1 Firefox window open, but I added up all the memory usage in the Task managers 'Processes' bar and it doesn't add up to that much. It also says I have 56 processes, only 23 of which show up in the processes panel. Im really not techincally minded, I just had hoped that when i first got this pc that 2GB of ram would not have been used up so easily.

When I put in a CD and install a program, my Mem usage sometimes goes to 100%, and stays at 100% even when it is finished installing. Everything runs insanely slow, and I usually end up holding the power button to restart (if I click on the start menu to restart, it takes 15-20s for the menu to come up). I say it happens sometimes, because it doesn't always happen. It is hit or miss. It sometimes also happens when doing other tasks (see below). However, when I open up task manager (and display all processes), I do not see any processes that are using an insane amount of memory. Everything looks normal. Also, today I was backing up ~3.5gb of files from my hard drive to my external drive. My memory usage went to 100% and stayed there, just like I mentioned before (had to power off).
Just to get all of the starter questions out of the way:
-This is a fresh install of Vista x64 with SP1 (SP1 is up-to-date)
-I do not have any viruses
-I do not have any spyware
-I have ran memtest for 16 hours just to make sure it wasn't my RAM
-I have no messed with the pagefile
-UAC is enabled
Also, when I run a program like prime95, my memory usage goes to 100%, but when I hit "stop", the mem usage goes back to 30-40% like it should. So things are working okay. I have had this system up since June. It is not a HUGE issue, because most of the time I am not installing anything, but when I do install something, it sometimes requires me to reboot.

Both pre and post SP1 whenever I install a game my memory usage starts to climb. It usually hovers around 30-33% at idle. While installing it eventually peaks @ 99-100% and will drop to about 95-97% after the install is finished. For the life of me I can't figure out whats causing it.
I just installed lost planet and had the same issue. It happened with COD4, Supreme commander, and Crysis too. I've added screnshots from during the install, post install and after I reboot (because the memory does not go back to normal until then).

I am getting intermittent memory error message saying the pc has run out of memory and trying to track down what is causing it. When I boot up the pc I see Physical memory of 3.325 Gb and used memory of 1.04GB 32% in task manager. When i go to Resource manager I can't understand which of the different types of memory (Commit, working, private) make up the 1.04 reported as used. If I add up all the processes under Working Set it only comes to about 600Mb. So 2 questions:
a) Are ther other OS processes not listed in resource monitor that are using up the unaccounted 500Mb?
b) Is Working Set the right type of memory to be monitoring to see which p[rocess is causing the reported % usage to climb so much?
I'm intending to writie down each porcesses usage every 24 hours ot try and identify the culprit. Strangly the problem has only appeared since i increased the RAM from 1Gb to 4GB!

I'm running Vista Home Premium 32bit. A couple of weeks ago, I noted that something was causing the explorer.exe program to spike in its CPU usage. When this occurred, CPU usage would immediately spike to over 50%, and would never drop below this level without closing out and restarting explorer.exe in the task manager. If I tried to click on another folder after the 50%+ spike, explorer.exe would immediately spike to 100% CPU usage, and nothing futher could be done until explorer.exe was closed and restarted in the task manager.
In trying to discover the root of the problem, I found that this was happening whenever I clicked my shortcut to open Windows Explorer. This didn't happen, though, when I simply opened "My Computer." Further examination has shown this strange phenomenon to be what's causing the issue: any time a link to the "Documents" folder is clicked, the CPU spike occurs. This only happens when "Documents" is clicked in either the "Favorite Links" pane or the "Folders" pane below it. I can navigate to the "Documents" folder the long way (Users--My Name--Documents) and the spike does not occur. Also, I can click in any of the sub-folders (and all of their sub-folders) within the Documents folder from the "Folders" pane without the CPU spike occurring. The spike only occurs when the Documents folder itself is clicked from either the Favorite Links pane, the folders pane, or upon opening to it directly by opening "Windows Explorer." So, while I've found a workaround that prevents the CPU spike from occurring, the problem still exists, and I'd really like to be able to find the solution.

I just want to know how to optimize vista,I run very few programs except Zone Alarm Pro and Symantec antivirus. But in the task manager, there are 80 running processes, and 50%+ physical memory,the CPU usage is usually 15%-50%. Is there any professional software to optimize vista PS, friends told me vista is crappy and xp is better, but I have no other choices cuz the OS is from the HP.

since a few days my cpu has always cpu load of about 90 % at core 2. Vista is very slow. Taskmanager shows no applications with cpu usage. Now i installed process explorer and i can see that 45% cpu usage (this is 90% of core 2) is for "System / hardware interrupts". Which interrupts are the problem, what can i do to fix this?

I have a big problem! Yesterday everything was fine then all of a sudden I could not delete certain files and every time I would open an explorer window another window would open and to finally get to where I want.. I have to open all of these windows very annoying. Also I have never had all the folder options like thumbnail view and so on. Thing is most of this was fine yesterday. I do believe it might have something to do with running CC cleaner because after that all of my setting for explorer were lost. and now I cannot get them back.Then when I tried dragging certain files into other folders I would get a message saying "Target cannot handle this object" I tried in folder options to reset folders also to open folder in same window but nothing. seems Vista is not responding to my requests . I have a UAC tweak installed to minimize vistas requests for confirmation and also had sp1 installed and uninstall ed it but all of this happened before the uninstall of sp1. This started with the cc cleaner so I deleted that don;t trust it anymore seems it has deleted all my vista settings.Also in folder options i do not have the option of viewing thumbnails which is also annoying because I cannot see the photos I want when I want to choose a photo for instance to post on a blog or other.All this is very annoying and the worst of it is that I cannot do a system restore because I have not restore points prior to cc cleaner. shoot what to do?

My cursor (not the mouse cursor) won't stay in one place. It jumps from field to field in just about every program I use, going from left to right, just like I'm pushing down the tab button on the keyboard. I'm on a desktop and not a laptop. It makes it very hard to type or to chose options in pop up windows. It makes the scroll bars move all by themselves too. I tried updating my keyboard driver without any improvement.

My mouse (cursor) is very erratic - jumps all over the place without warning, sometimes disappears for several seconds. I have to chase it around to bring it back in control! It is a laser mouse. I tried another one from another computer that I know works, and I have the same problem.

My computer jumps backwards on most applications. I thought it was internet explorer, but it happens even when I'm using Word. It acts as though I clicked on another area with the mouse when I didn't...most of the time I am not even touching the mouse.

when I am typing an email it seems that I can only type so much and then my curser jumps backwards into another part of what I've typed. It's done it four times now as I am typing this. Is it mail? Is it something else?

Trying to work out kinks on my Vista 32 bit. After clicking print in Windows Mail, it automatically jumps to an open Internet page, and then I have to click back to the Mail. This is driving me nuts.

I would like to ask you to Google for FileCopy/progressbar problem and see how Earth is filled with us - morons. My progress Bwr keeps dancing left & right, calulating time remaining (always lying by a huge marging unlike WinXP), but it's not too important. Important is that data transfer rate jumps from 16Mbps down to KBs periodically as it scans thru multipel files. All it can fast is copying a SINGLE large file, even that estimating time remaining and progress bar are not as good as in WinXP
This is one of the 500 admitted bugs Microsoft admits to in Vista and its a beauty. I hate to keep harping on the same point, but it makes absolutely no sense to me how such a basic function not just gets screwed up, but WHY Microsoft would ship Vista with such a obvious bug in it. It totally trashes their reputation. Oh wait, we're talking Microsoft. We know their reputation. Ship and fix later. Everybody knows whatever version of Windows we're talking about WAIT for the service pack before most of the bugs are out.

Memory DiagnosticsIf Vista detects a memory problem in your system such as a faulty RAM module, it will display a notification asking if you want Vista to try to diagnose the problem.Then again you may also recieve the sudden BSOD with the error MEMORY MANAGMENT at the top. You can manually run this tool anytime just typememory in the search box inside the start menu.This tool offers you two options: restarting immediately and checking for problems, or running next time you reboot your machine (the memory diagnostic tool must run at boot time).
Network DiagnosticsWindows Vista also allows you to check the connectivity of your network connection using the Network Diagnostics Framework: An infrastructure and a set of built-in and extensible components that attempts to automatically diagnose and correct network connectivity problems. The usual way to run this check is to open Network Center and click the Diagnose Internet Connection link on the left Vista will either identify ............

I had 4GB physical memoryon the PC. With Windows vista 32 bit, available memory is shown as 3.3GB. I asked and was told that only under 64 bit windows, will the available memory be 4GB. When I upgraded to windows 7, I chosed 64 bit, but the available memory shown in the system is still 3.3 GB. Why is this and is there a way to make the full 4GB available? It's possible that my video card is using RAM instead of its own RAM. If I install a video card with its own RAM, will the full 4GB be available?

I have a problem with Vista Ultimate x64 SP1, I always seem to lose all my free RAM within an hour regardless of system activity, even while idling. I have noticed an svchost.eve process runs each time I reboot which seems to bloat constantly although when I close it down it only frees up about 800MB, what's happening to the rest of my 8GB??? When I launch Task Manager it says I'm only using 10% Memory but free RAM sits at 0?!?!

I am fairly new to the forums, and VERY new to Vista x64. The machine is new, and I was trying out some apps and games, I was in Secondlife when I got an error messege saying I was out of memory and needed to free up memory. I shut down the app and restarted it. Runs but I watched Task manager and saw my free memory down to almost nothing after an hour or so. The cached seems very high.
I did alittle research and decided to set a second page file on my 1TB hard drive, (OS is on the other HHD's )( regulated by system for size ) I'm not really sure whats going on. Example of just task manager and this page openis attached. Again, any help would be great in getting the memory set up on here optimal.

I have 6gigs of DDR3 memory at 1600hz. Running on Vista 64bit and every now and again my memory performance just maxes out. The problem can occur around the time when I am installing something but I dont think its always this way. I have read forums where it could be the hardrives performing self diagnostics. I have all the latest patches for vista.
