ProfSvc
MMCSS
LanmanServer
iphlpsvc
IKEEXT
Browser

First of all, i have 13 svchosts running. I seem to recall around 3 in windows xp 32. Is this normal? Second, one of the svchost.exe's is ALWAYS using 120+ mb of ram. This can hardly be right, can it?

One of the most common questions about system processes is what is svchost.exe and why are there so many processes running? First appearing in Windows XP, svchost.exe hosts multiple services within one process. This allows the operating system to save memory by reducing process overhead by cutting down on the number of processes that need to be running.
Every system service such as Windows Update, Event Log, Terminal Services, Audio Service, etc. runs within svchost.exe. Depending on the access the services need, they are grouped together and are run in a number of processes which explains why you see so many in Task Manager running under different accounts such as System, Local Service and Network Service.
Identifying what services are running is different depending on the version of Windows you have....

I have Windows Vista Home Premium, and one of these days I saw that the processes svchost.exe should be running. I open my Windows Task Manager, and there is no svchost.exe anywhere. Not a single one!

The svchost seems to be spiking my physical memory at startup to around 80%.. and it only drops to around 75% And i also know that my computer cannot run to about 93-98% on memory because i suspect Faulty ram from previous problems of mine.( I will be replacing it with 4gb in 1to 2 weeks) Also after disabling Pc tools threatfire & Pc tools firewall i seem to be getting alot of processes which are also playing with my phiscal memory %. b4 i uninstalled The pc tools programs there was only 2-3 svchosts.exe now there are about 13 of them..
Name Memory(underneath each svchost are the services)
svchost.exe 1628

svchost.exe 1984
RpcSs
svchost.exe 3708

Vista Basic Machine started running very slowly and when I looked in Task Manager svchost.exe was using a 100% CPU. Using system internals process explorer it???s the network service containing crytsvc, dnscach, KtmRm, NlaSvc, Tapisrv and Termservice. Looking inside the thread that is using the CPU is ntdll.dll
I???ve ran all virus and spyware checkers I can and all show no problems. I've booted in safe mode and cleared all the softwaredistribution folder. The slow running does not affect safe mode but as the service is not started no great surprise. Windows Update doesn't work in safe mode either, thanks Microsoft. I tried to update AVG virus checker but it wanted KB929547 applied so I downloaded it and tried to run but after several hours all I got was install failed with 0x800706bb

I started noticing about just 2 days ago. whenever i am playing a movie or any audio file, its not clear because the cpu is being used completely 100% most of the time. I checked the task manager and found out that svchost.exe is taking up most of the memory and cpu! any solutions so that i can fix this, i dont think i can end process svchost since it runs some important applications on windows.

Two days ago i downloaded a program(Single file abt 100 kb) and executed it. After execution the program's icon simply disappeared from my desktop!
After that I have been getting resident shield pop-ups which tell me about a new file being created in TEMP directory.
eg: FILE NAME: C:windows empcvnp.tmpsvchost.exe
THREAT NAME: Trojan Horse Clicker.AEIO
Detect on open.
PROCESS NAME: C:windowssystem32svchost.exe .

I've been a reader of the forums for a little while and found the need to make my first post. Let me preface, that I've done some searching on this issue, tried lots of things, and found nothing to help resolving mine. I'm running Vista Ultimate X64 SP1. It seems that SVCHOST.exe is causing the problem and I've attached a screenshot of the associated services. The problem seems to be random in terms of when it acts up, but quite often. The only temporary resolution is a restart.

This file called SVCHOST.exe is consuming my RAM, hard drive, CPU and everything on my Vista machine to capacity use. I know the real one is a necessary program, but there are many copies of this file working simultaneously here and my performance is down to a crawl or a crash. I've looked everywhere for a solution and have tried a couple to no avail. I get no working answers from anyone. Many, many other Windows users are getting this in massive amounts, too, so it's not isolated to me. Everything slows to a crawl often several times a day. I often have to restart. I am told it might be one or more viruses that does this, and I've been told it might be an unfixed bug in Vista, but no square answers. My scans and virus updates from Norton and MS haven't fixed this problem. I am now seriously thinking of copying my whole disk to an outboard memory and reintalling Linux on my machine instead of Windows Vista, as no one seems to want to address this issue in the Vista world, even though it is obviously a very prevalent problem.

I have installed Windows Vista in system. After logging into my system,when the desktop appears, i am seeing a command prompt running the below files each time i am logging in C:Windowssystem32tvdm.exeC:UsersusernameApp DataRoamingsupportsvchost.exe
I would like to know what these .exe files are basically and how to make this prompt window prevent from appearing each time when i am logging in. Whether this affects the OS & any of the system files/drivers or whether this is a virus,trojan or any kind of that.

In my network, sometimes my user's laptops freeze during the logon script. Well the computers don't actually freeze, they just don't move beyond the logon script. When I go into task mamager, cpu is running at 100% (2 gb ram and very new processors) and the process taking up the most memory (48,748k)is svchost.exe I think it's associated with the windows search indexing but I'm not completely sure. On the Microsoft support site I saw that I could use the command tasklist /svc to see what is running in svchost. But I haven't figured out yet how to determine exactly what this svchost process is assoicated with so I can prevent it from running all the time.
