Hi all,I have a new problem. I tend to download weather using FSMeteo using the download and stay offline option, then get offline and do my flying. However, lately when I do this, I get regular stutters at about 15 second intervals where my framerate drops down to something like 2-4fps. Because of the precise regularity of the stutters I minimized the sim and opened Task Manager to check what was going on. Turns out that one copy of svchost.exe (there tend to be two or three running in the background) at regular intervals takes up to 50% of the CPU usage. This is even though I am offline by that point. I tried terminating the process but I get an 'access denied' error message and the svchost.exe just keeps on stealing processor power for whatever in the world it thinks it's doing. If I reboot the machine and restart the sim and FSMeteo using a wx file I downloaded earlier, the problem goes away. Does anyone know what's going on here and why my own computer won't let me shut down svchost.exe? Thanks in advance. Misha

svchost.exe is a service (it is an application that works as a host process for services that run from dynamic link libraries.)...You are not allowed to shut down services through task manager. You need to use the Services MMC in Administrative tools.svchost.exe acutally can be one of several services. You won't see it listed in Services.You could try my FSAutoStart program and shutdown unnecessary services before running MSFS and see if the stutters go away.Regareds,

I will try the Administrative Tools route this weekend. I thought about trying to do it through FSAutoStart, but I think it has to do with the FSMeteo connection. I usually first start up FS and load a flight, minimize it and load weather through FSMeteo before returning to the sim, which means that FSMeteo will connect to the web after starting FS, so I am not usre FSAutoStart will help.

One of the things that may help you is to reduce the Weather Coverage Distance. The stuttering problem that affects me is when it sets the global weather. By reducing the distance, it reduced the stations it sets, thereby reducing the stuttering time.

There's one relatively easy way to discover what's bugging you...But before I explain it, I can tell you that some versions of Norton Antivirus tend to do this.OK so... Open services page, and you'll see bunch started and not started services. Sort them so that you have started ones on top of the list. Use this page http://www.blackviper.com/WinXP/servicecfg.htm to determine which services are safe to switch off. If you only wish to find the svchost.exe service, you will have to open each service, and read it's "Path to the executable". Example: COM+ Event System - C:WINDOWSSystem32svchost.exe -k netsvcsNow, deactivate the ones that you can, and see which service is bugging you. I think you can switch off all services except RPC. See about in on the Viper's page.Hope this helps...

Thanks Word Not Allowed. That sounds good. I will try that.Steven, it has nothing to do with weather coverage distance. It happens if I am sitting on the ground, not moving and even if I exit from FSMeteo and reset the weather to default or cancel all weather. I know the stutters you mean, those occur in flight and reduce my framerate by a 25% or so for a moment when I reach new METAR reporting stations. This is worse and has nothing to do with that. It's an svchost issue.Misha

I would also check you don't have a virus Misha, IIRC one of the recent viruses installs an svchost (or similar) file.

it is a keylogger,i suggest you at least disable it.type in svchost.exe in Google,you'll see what i mean ;-)EDIT: i'm dumb...if you ever come across svcini.exe,that is a keylogger.please ignore anything i said(like you didn't do that already ;-) )
