Explorer Is Showing Incorrect Disk Usage
Nov 14, 2011
I am using Windows 7 (x64) and I am getting incorrect disk usage reporting through Explorer. I am looking at a 1TB disk, which with partitioning considered is showing as a 931GB disk - however even though I am using only 421GB of the disk space Windows 7 (Explorer) is showing that there is only 202GB free on the disk.As you can see above I selected all of the files on the disk, right clicked, selected Properties, and the results of my enquiry are shown (superimposed over the Explorer view).

I am having a hard time figuring this one out. I can restart explorer.exe and the problem goes away temporarily. I ma not sure what program is starting the problem though. Process explorer is showing that "shlwapi.dll!SHRegGetUSValueW+0x1a4" is to blame

My C partition is 100 GB and I have my page files are on a different drive. So pagefile.sys cannot be a problem, could it?

I'm running Windows 7 64bit on a notebook. One 500GB drive partitioned to an OS drive and a data drive.I run AVAST (paid version), Malware Bytes and unhackme and no viruses/trojans/rootkits discovered - I'm a stickler for security.I noticed in Windows Exploring that both drives were getting low on available storage (both <8GB). I copied 30GB from the data drive and 10GB from the OS drive to an external drive and deleted the files from the notebook, using shift key/delete. I cleared the Recycle Bin; ran Disk error check (Scandisk) and defragged both drives.Folder Size & Treesize Pro both tell me I have 180GB & 100Gb respectively free; versus Windows Explorer 5Gb & 6GB.My available storage only increased by 800MB and 600MB respectively after deleting the files, so for a file removal of 40Gig I get back 1.4gig of HD space.I've checked pagefile.sys and hiberfil.sys [8GB between them] and they haven't altered recently.Ran CCleaner's Registry cleaner - no difference.I rang the OS support for my Notebook Manufacturer and spent 1/2 a day trying different things including HD tune. They couldn't figure it out but suggested Utorrent may be grabbing HDD space so I uninstalled it.... no difference.

So I can't change the drive letter. Do I need to use Partition Magic again? The more I keep hearing/reading "do you have a backup?" - makes me believe the tool (OS) isn't capable of handling/accessing the data properly.

I had to do a clean reinstall, before it was showing all 4GB of ram as usable but now only 2.75GB. It is 32 bit but was using all 4GB before on the same system.I've been into msconfig and the boxes are unchecked, strange.

i have just finished a remote assist with Microsoft to try to resolve a problem i am having with my win 7 os. It appears from my trolling the forums that it is not an uncommon scenario. As i use my machine i see the memory monitor gadget showing more and more usaage of ram until finally i get a "not enough resources to run application" prompt.
The guy from microsoft cleared my cookies, my prefetch files, google toolbar etc without effect. He suggested that some of my optimising utilities could be the problem until i explained that i had installed the to try to CURE the problem. He finally cleared off without saying anymore and i was left a link if i wanted to resume the chat support. This link didn't work. Any comments would be great.

started noticing how explorer.exe keeps using loads of my CPU power, earlier both processes were using 40-50% of my CPU causing everything to work extremely slow/stop working, now one of them seems to have cooled down and it's the other one running at 48-52% the entire time. Has anyone got any idea why this is happening?

My computer has been using a lot of memory and cpu usage lately and its mostly from my desktop or the internet. When I check my processes, its mainly explorer and dwm (desktop windows manager) that's using the most. I have ran a lot of scans already and no malware was found. Here's a link of all my logs [URL]. I would like to have my cpu running at full speed again.

I've been having major problems with svchost.exe.. From what I can gather, this process relates to Windows update service; and I don't want to end the wrong process (since each leads to one or more separate locations) I would like to know what I can do to remedy this; because it is extremely irritating! I am also having trouble with Explorer crashing, which of course bombs my desktop.. I've been experiencing missing paths for icons, even the parent location of an executable program shows the standard 'file' image Image reference : The latter of those two is the containing folder for that program of course; and the .ico is related to the file within it's properties, but does not show on the desktop or explorer window! )

When I put my computer together, I decided that an 80 GB drive would suffice for the C: drive as the only stuff to be stored would be the operating system and programs.However, the size of C;Windows seems to grow without bounds - it is currently consuming 31+GB, which is simply ludicrous.

Antivirus: Symantec Endpoint Protection, Updated and Enabled
Now to the actual problem. The reason I bought all this RAM was so that the computer would run faster and more smoothly. Despite the large amount of memory, however, I still experience frequent spikes in CPU Usage, which I have learned is not related to RAM very much if at all. Regardless, I would still assume that my system wouldn't have to overexert itself to run simple tasks like Windows Explorer (i.e., folders, desktop and taskbar) or the Task Manager itself.
Either of these tasks, as well as others such as "System," "svchost," or "File I/O Surrogate" (none of which I know much about) can spike to anywhere from 30-70% of the CPU without warning, and when it does, the total CPU Usage ends up being 100, which REALLY makes my laptop sluggish and unresponsive.
I understand that RAM does not directly impact CPU Usage, but I would also assume that, since my laptop isn't ancient, that its CPU shouldn't struggle to display my folders/desktop/taskbar, or to run the Task Manager itself. I also run a daily virus check with Symantec Anti-Virus, so I don't think infection is the issue. In addition to that, I monitor memory usage alongside CPU usage, and the memory usage never goes higher than 10.5 (it usually hovers around 6-8) or so GB of my available 16-- insufficient RAM is also probably not the problem.

My Win 7 (64 bit) computer with a Intel i5 760 CPU, 4Gb of ram and AT Radeon HD 7500 Graphics card has developed a problem with about 25% constant CPU activity and constant disc activity. Task Manager shows that this is due to the "NT Kernel and System" process, and it can't be stopped. The surprising thing is that I get exactly the same problem in Safe Mode with no connection to the Network, so what the heck is going on?

I just checked my C: Drive for usage and it says that I am using 351 GB. I have 331 GB left, but I am curious as to where the usage of that amount of hard drive space is coming from. I hardly have any programs because of the clean reinstall and the current program sizes are no where near that capacity. The videos and pictures I transferred over combined it about 50 GB. Where is the rest of my disk space? I would like to clean my hard drive as much as possible. Restore points are also limited to using 10 GB as max. I have run CCleaner and Puran Defrag at least twice.

The L: drive is newly installed and only ebook files are on it. What might have caused this and can it be corrected?

I used to be able to view the cursor thumbnails like normal. But recently, the cursor thumbnail wouldn't show. I've attached a screenshot of it. I am still able to change my cursor, and it works fine, it's just, in the windows explorer the thumbnail of the cursor shows a Photoshop icon. Only the .cur file is affected, the .ani is not.

In Windows 7 Explorer, the Computer icon is not showing in the left pane--neither in the default view or the 'show all folders' view.
You can see from the screen captures that I have Explorer set to open to Computer, but no Computer in left pane, and no drives are accessible directly through Explorer.
The drives are fine (from using alternate Explorer alternatives).
How can I get the Computer icon back in the left pane?

I have a computer that was running fine for a year or so, but now its been a couple of days and after an hour or two of use, it slows down and finally freezes. I don't know what it is. The clues I have include:
-I've run memtest86, no errors.
-I've scanned the whole system with 4 different virus programs, so not a virus.
-But I've noticed that rundll32.exe has been using a lot and I mean a lot of resources. After a couple hours, nortron tells me that it has high disk and cpu usage. I checked core temp, 100% on all 4 amd phenom 955 cores. I don't get it.
Specs are:
Amd phenom 955 be
4 gb crucial 1333
ati 5450

I bought a M1530 on the cheap a few months and installed Win 7 x64 with a lot of research primarily from here. Everything worked perfect. The drive is a Teac DVW28SLC. It's a slot load and the only eject button is with volume and DVD controls above the keyboard. I needed to burn something to DVD. I decided to try Imgburn for the software.Installed it, popped a fresh DVD-R in. DVD drive recognized the blank. I usually reboot a computer before burning, realized I didn't so I rebooted. Now, the drive no longer works.
After the reboot:
-Drive is visible to bios.
-Drive cycles on boot up, checking for a disc.
-Drive is not visible in explorer
-Drive is not visible to diskmgmt.msc
-Drive is visible, not disabled and properly installed in the device manager.
-Card reader also seems to not be visible either but is showing up in device manager.
-Disc will not eject from keyboard button.
Things I've tried to fix it:
-Several reboots.
-Uninstall Imgburn.
-Uninstall Daemon Tools Lite.
-Uninstall Drive in Device Manager, then reboot.
-Uninstall Drive and ATA controllers then reboot.
-Delete upper and lower filers at HKLMSYSTEMCurrentCOntrol SetControlClass{4D36E965-E325-11CE-BFC1-08002BE10318}, no entries were present.
-Reinstall chipset drivers, though I don't think Intel installer changed or installed anything.
-Fixit does not work.

Bought a LG Blu-ray internal sata rewriter. Installed it and windows 7 found it first time. So far so good. Put windows into sleep mode and when I woke it up the sata drive was missing. The drive was not only missing, but the tray failed to manually open and the activity light did not illuminate. Drive totally dead. Check all power and sata cables all ok. Done a full reboot and drive came back ok. This only happens when the machine is put into sleep mode. Sata drivers all up to date and all cables 100%. Turn the machine fully off or restart and everything works ok each time. Use sleep mode and it fails when you bring the m/c to life.
