Latest Windows Update causing slowdown?

by Disneyfan / October 14, 2009 10:15 PM PDT

This week Microsoft released quite a few updates. Since then, my friend's Windows XP laptop has become very erratic. It runs extremely slow, then suddenly speeds up for a very short while, then slows down again. This just started happening yesterday (Wed 10/14). No other changes have been made for a long while but the problem just started yesterday.

Does anyone know of any new updates that may be causing this?

Think about the Indexer.
by R. Proffitt Forum moderator / October 14, 2009 10:37 PM PDT

After changes the Indexed (AKA indexing service) would, could run for weeks. Do you remember that?

Also your antivirus might notice and want to scan the entire machine.

Between these two I'm taking bets that many forget how our machines work and this can cause many to think MSFT has failed them.

The owner had just installed Norton 360 but the problems had started prior to that. So we removed Norton 360 temporarily to see if that was related to the problem but then even with no security installed, the system was extremely slow. By the way, I had scanned the system with several scanners, including Malwarebytes, just to be sure and got no hits.

As far as the Indexer, that is true but it should not be bringing the system to it's knees. We are going to try a System Restore and see what happens.

So you don't own this?

In reply to: Hmmm...

Since you don't own it, get off their machine so they don't blame you for the troubles?

Not an option...

I have my own computer service company that I run out of my house but primarily do house calls to residential accounts. The business has grown and is working out well.

So this happens to be a customer of mine that I am trying to help through this.

Seeing similar thing here- on several systems
by rjfloryal / October 30, 2009 2:08 AM PDT

I first noticed the slowdown on Oct 14.

We use our systems to compile large embedded software projects, launching concurrent compiles to take advantage of multiple-core cpus (quad in my case).

Suddenly my build times jumped from 9 minutes to nearly 30 - overnight.

The builds used to keep my system at 100% load for the entire build, now I'm lucky to peak out at 35%, mostly hovering below 5..15%.

I see no improvement at all between single-thread and multiple-thread builds- which is contrary to how this recently built systems worked before the 14th.

Symantec virus scans come up negative.

I install very little 'junk' on this systems- no games, no fluff, however there was a micro$oft automatic update on 10/10- just before the launch of windoze-7.

You don't think they pushed a 'cripple' patch for XP just to drive users to upgrade to upgrade to windoze-7 out of frustration? nah...

So What Happens When...
by Grif Thomas Forum moderator / November 2, 2009 6:01 AM PST

...What happens when you..

1. .... disable the Indexing Service?

2. .... uninstall Symantec?

Or to narrow down the culprit, start disabling unnecessary services ... You don't mention your operating system, but if it's XP as the original poster, try using the "Tweaked" column in the chart at Black Viper's link below:

We've had no such slow down on any of our machine here..

Hope this helps.


Hope this helps.

Resolution of this problem
by rjfloryal / November 2, 2009 9:31 PM PST

Deleting all entries from "Network Neighborhood" and "Network Drives" (mapped drives) corrected the unexpected delays encountered when launching programs or child processes. I had previously cleared the "Network Neighborhood" many times, so it was empty, but there was one mapped "Network Drive" that silently hosed the entire system.

You can always re-add mapped drives if/when you need them again. Apparently windoze has problems with old (stale) entries.
