Long Start-up time

May 27, 2007 1:44AM PDT

Off late, my computer was taking extreme long startup time (upto 35-40 mins). I went into start-up services through msconfig and disabled all services. Then I enabled each service one by one and finally found the culprit. I have three instances of WMI in the list of services. I have enabled WMI (appearing only as Windows management instrumentation) and disabled WMI driver extension and WMI performance adapter. The start up time is now back to normal.

Can anyone tell me what the disabled services (WMI driver extension and WMI performance adapter) are for and why they take so long time if enabled? Possible infection? IF I run without these services being loaded on startup would I have any problems?

Problems? Yep. . .

Open Administrative Tools in Control Panel. Click on Services. Scroll down to WMI, double click it and look at the Dependencies tab.

Why it's slowing your system down, I don't know.

and... The following system components depend on this service
- Security centre
- Windows Firewall / Internet connection sharing (ICS).

WMI driver extension has no dependencies.
and WMI performance adapter is dependent on Remote procedure call (RPC)

The machine's long startup time is not because of those services and such. Something changed such as spyware, malware or other issues. Find that and fix that.

Tell what spyware and other scans you have performed.

I had NIS 2007 installed till yesterday...
May 27, 2007 5:49AM PDT

and I was having all sorts of problem. I then changed to KAspersky and it immediately found 2 trojans and deleted them. I uninstalled NIS before installing KIS. NIS however didnt find any threats. In addition I am using Spybot S&D and Adaware SE. Once I also run Windows defender and it came out with nothing. Since this morning I am running the comp with the two services (WMI driver ext and WMI performance adapter disabled) and the computer is running normal. (WMI is enabled though).

I have a Sony Vaio notebook with 1 GB RAM. Please let me know if you need further details. Any help would be much appreciated.

This is AVG antispyware online scan. I have done that a couple of weeks back including Bit defender and a few others I dont remember the names now). They all came out clean.

Now a drive fitness test.

Let's make sure your drive isn't failing. The drive fitness test should be from your drive's maker.

How to know ..
May 28, 2007 7:11AM PDT

the manufacturer of hard drive? Do I have to open up the computer to know manufacturer or is there another way of knowing? and how do I do a drive fitness test? (I think the drive maufacturer is Toshiba but I am not sure). Do I have to download any software from Toshiba website?

I use these tools to figure it out.

1. BELARC ADVISOR (see google.com) BIG HINT!!! Print that out and save with your documentation.

2. EVEREST FREE EDITION at google.com. Lots of information that I use at times.

I installed Belarc advisor and

ran a scan. It didnt report the hard drive manufacturer. It just reported the disk size and a long alphanumeric character. I have now set WMI performance adapter and WMI driver extension to "Manual" and everything seems to be running fine.

"have now set WMI performance adapter and WMI driver extension to "Manual""

How did this change from it's stock settings? There was another member complaining of slow PC syndrome but they didn't share what changes they had made.

I dont know....
May 30, 2007 10:21PM PDT

how the settings changed but when I was doing this exercise of disabling and enabling each service one by one I found that enabling these programs leads to a very long start up time. At the time of changing, these 2 services were set to "Automatic" which I later changed to "Manual".

Links that note the default was Manual.
