Explorer.exe Using 50% CPU Time When Idle
Mar 23, 2008
explorer.exe is using 50% CPU when the computer is idle. This started after being in hibernation for about 6 hours. I can log in, but have no use of the task bar. I can click on a program icon on my desktop and the program opens with no problem. When I mouse over the taskbar, either nothing happens or my cursor changes into an hourglass. I cannot use the Windows key on my keyboard either. If I use Task Manager to stop explorer.exe and then restart explorer.exe - the taskbar works normally for a while, but explorer.exe is still using at least 50% CPU time when the computer is idle............

When my Vista Home Premium-SP1, is idle for awhile, the computer freezes. the screen is a grayish color and the mouse circle just keeps twirling. I have to manually re-boot. Everything is fine until I leave and come back...and it is frozen again. I cannot ctrl-alt-delete either. When I went to do a system restore, I saw that all my restore points were gone. How could this have happened? I thought maybe a windows update could be the source so I uninstalled the many updates (approx. 25). the next morning, I saw they had all returned even though I have it set not to download automatically.

PROBLEM: I have an XP laptop that I'm using as a file/print server, with two Maxtor external USB drives, and an HP color laser printer. I have a home network to which I've connected several computers (a wireless XP laptop and two Vista desktops, one Ethernet and one wireless). When I first booted up all the computers in the morning, my Ethernet-connected Vista desktop could access the HP printer and the Maxtor external drives. Thereafter, at some time later, I couldn't get to the XP laptop, nor the printer, nor the Maxtor drives. When I would click on the mapped network drive, I would get the "The specified network name is no longer available". If I rebooted, all was well -- for a time. I could never figure out a sequence of events that was causing the problem.
UNTIL... I came across this thread and your tutorial Network Idle Session Time to Automatically Disconnect ... OMG!!! THE SOLUTION. Life has been SO good since I set the autodisconnect to 'never'. Disconnect. Geez. I had no idea there was such a thing as Network Idle Session Time.

I have an HP laptop using Vista SP-2. Until recently, the power settings worked the way I set them (especially shutting off the display after 15 minutes of idle time). Now, this particular setting doesn't work (the display stays on all the time). I haven't checked the other settings yet. Tried Google but couldn't find anything that applied.

I recently went into Change Date & Time Internet time tab and chose a time standard to connect with. After doing that I went onto the internet and connected with time.nist.gov and checked the time. After that I was no longer able to go into the internet time tab. It tells me that time.nist.gov is the time connection and I can't change it. It tells me I need to have permission to do this as administrator. I am the administrator! What goes here?

A long load time when a user starts Internet Explorer is one of the most common performance issues seen with Internet Explorer 8. The primary cause of this problem is third-party add-ons that were either preloaded on a new computer or bundled with other software and installed over time. These extra mini programs must be loaded along with the core Internet Explorer code every time Internet Explorer is launched
Internet Explorer 8 includes a very handy feature that will help you identify how much time each add-on in Internet Explorer is ....

and I don't get it. 'windows internet explorer has stopped working.' and then sometimes when I start it---the links are all missing. All I have is the basic IE7 with the Yahoo toolbar, latest version. The next time it happens, I will take a SS. I may have to go to FF which is not my preference. How do you get FF be the default browser for yahoo mail, for example?

When you are in explorer and are manually typing in a long folder path or at a command prompt navigating through many directories, below are two cool tips that will help you save time.
The first is one that I have been using for years. When working at a command prompt, instead to typing in the full text of an item, just hit the tab key to bring up full items. For example, say I want to change the directory to the Windows folder. At a command prompt I would type in CD wind and then hit the tab key and "Windows" will automatically show up. Think of the tab key as a kind of auto complete for DOS. This same technique also works in Windows Explorer.....

measure the ReBoot-Time (restart time) for our systems. You can see how to here: How to See What Your Boot Up Time is in Vista
Here's my ReBoot-Time:
Running Processes: 41
Started Services: 36
Automatic logon

We are using Dell laptops while travelling or at field offices.
We have to reset the clock and time zone, every time when we get to new
locations. That is quite a hassle. Is there better ways to do this?

At idle, I have 50% cpu usage at times. It seems to be msiexec.exe. I have absolutely no idea why. Is this a normal Vista behaviour? Second, at startup I have 67 processes running, then it jumps to 72, then back down to 67. I had this amount on my XP pro machine, but had probably over 60 different programs installed, as it was a shared machine with CAD programs, graphic design software, etc. Now I only have vista, adobe cs3, blackberry, and office... And for my final question, Why does eSata not able to "hot-swap"? Is this normal as well (sorry, I've always used firewire for my external drives, but now I'm trying to use eSata)

why my harddisc drive is very active and has allways been that.? It is mainly when I don't use the PC and it should be idle - I guess that the search indexer doesn't use so much capacity.

I installed Vista recently and now, when I've got all updates and I've installed few programs into Windows like Visual Studio, Mobile Device Center, some SDKs etc, every time the system is idle the CPU load is 50%, not exactly, but about 50%.
So I've tried to determine which process makes this CPU load. After Alt Ctrl Delete and Task Manager I haven't got to know anything. I've installed Process Explorer from Sysinternals. He told me process "System" makes this high load. I've tried to "kill" process "System". Yes, load felt down. But this isn't solution because after reboot it's the same.

I have Vista Home premium for 2 years. About a week ago it slowed to apoint where it may take 5 minutes to respond. Task manager Performance shows about 50% CPU usaage but Processes says 98% idle. If I start in safe mode Task Manager is the same but I seem to get a little better response. I use a free version of AVG.This problem seems to show up a lot in Google but each one seems to get resolved a different way. I tried some things others did but it has had no affect. The last time I started there were about 10 SVCHOST
processes. I ended a few but nothing changed.It takes a long time for one to end because the response is so slow.And it gets slower the longer I am up.
Where do I start to get to the bottom of ths?

I am using Vista x64 on my Laptop. The Problem - Vista Automatically logs me off, if i am inactive for 2 minutes (it brings me on logon page - and asks me to enter password) I have checked -
- Control Panel
- Screensaver settings
- Power Settings
- Searched on google
But could not find anything there. Can someone tell me, how can we set auto log off idle time in Vista :o ? Enable or disable this function?

My Acer laptop runs at 125 degrees F Idle, and it runs at about 160 F - 180 F when I play a game or do intense work. I was wondering how I can decrease the heat and keep my laptop cool. I've tried Speed Fan with no luck, and I haven't found any Acer Software to help me out. The computer it hot to the touch, and the temperature monitor is Speed Fan. I've even tried blowing out the dust in the case, and it doesn't fix it. I once opened up the bottom of my laptop, and saw lots of dust and blew it out. Most came out but some was left behind.

From time to time my system (Vista64) shuts down - when IDLE - for no reason. WIndows restarts and says: Windows recovered for an unexpected shutdown... error report send. How to debug? Note that the system is idle; only background processes are running.
What I've done sofar:
- Ran extended memory test: no problem
- Disabled power saving settings (as I suspected a problem going into hibernate/sleep). No effect.
- Disabled all "user based processes" as Picasa, Google indexing, CPU-temp watcher etc..
- Removed all USB sticks (no readyboost anymore)
I leave the system idle and 10minutes to 2hours later; bang; shutdown Note also that the system never chrashed when I'm actually working. So, not a severe issue but I feel intellectually challenged to get the thing under control.

I've got an Sony VGN-BX197XP laptop that I've upgraded to Windows Vista Ultimate. Since then I've encountered some strange display-related issues:
1) I could only boot into Aero about 50% of the time. The rest of the time I forced onto the Standard theme with no Aero option. Since installing Vista SP1 I can't get Aero at all.
2) When not running in Aero mode I can't get the Windows Media Player to play video files, nor get a Perfomance Index.
3) If I plug in an external monitor I can't get a picture on the laptop monitor but I *do* get a picture on the external monitor and it runs Aero 100% of the time. It will also play video files and give me a performance index.

Recently I have bought Vista Home Premium x64 and to be honest I am having quite annoying issue with this OS . I had installed Vista on RAID0 partition. Additionally I have three other sata drives for my data . I noticed that from time to time when I am working on vista , system freeze for 2-3 sec then everything is fine and I can continue work. Particulary when for example I am opening some application or even windows explorer , my computer etc. (when it hangs I can't move my mouse). Moreover when it freeze I "hear" something inside my computer case as if my computer weak up from hibernation.

Im in vista 64 bit. I was trying to install a licence for Cubase and was getting a time, calendar error. I look and everything is on time to the second hand on my wall. But for the hell of it, I tryed syncing it to all the availible servers but got: "An error occured while Windows was synchronizing with whatever.server" However I can ping the servers in comand prompt. And also, like the topic says, It still keeps perfect time. It set it's own time. So Im clueless. A bios thing perhaps?

This laptop is fairly new and both when I'm using it, and when it's idle at night, it will just restart for no reason. It's happening more and more, and no error code comes up.

I have noticed that my hard drive is busy doing something even while the computer is idle. I can't figure out what it is. I have turned off indexing, Windows Defender, and my system doesn't come with shadowing. (Windows Home Premium). I don't have any visible background programs running, (no antivirus programs, etc). The system restore is scheduled to happen daily, not all day long every day. Screen savers are turned off. Powering down is turned off. The computer is not connected to the internet. So what the heck is the computer doing when it's left idle? Why is it still grinding away computing something?

My new system was running at idle temps of 46c and under load (2 games and ventrillo running) it was sitting at around 61c @3.1Ghz. Now tempted to go a bit further to see how it will perform. I wanted to get the Thermalright Ultra 120 Extreeme but found it difficult to locate from local supplies but with more reading i found that a lot of people also had good reviews with the Zalman 9700 LED HSF setup so i was able to get that and man what a difference it made. I now run my system @3.5Ghz easy with idle temps at 38c and under load at 50c thats a damn vantastic difference it has made. extra rep points from me but i am not sure how to do that

I want to know how I can prevent my computer from going back to the log on page after it has been idle for a time. I would simply rather touch the laptop pad and just be able to pick up from where I left off instead of having to sign in all over again. I use Vista Ultimate. I have tried going to Personalization and the Screensaver page and checked to see if the On resume, display logon screen has been unchecked and it has been all along apparently.

I use my laptop to play an MMoRPG Game and I noticed it runs extremely slower than a few months back. I also noticed the System Idle Process is running and using 90% of the cpu. Is there anything I can do to speed up my computer or to stop the System Idle Process from using up all the CPU?
