Vista - Vista SP1 Memory Leak?

Hello,
I've been running Vista on a few PC's since release and haven't had any real
problems until SP1.

The issue I'm running into now is all of the PC's I've updated have a slow
memory leak since upgrading to SP1. After about 2-3 days of use,
explorer.exe is up to 400-500MB Commit & Working Set. This is up from
29M/49M a few hours into use after a fresh boot. Also, there is a svchost
network service that balloons up to >400MB.

The system becomes extremely sluggish and slow, with Physical Memory listing
as 70%+ versus 17-23% up to 2+ hours after a fresh restart.

Performing a fresh restart fixes the problem. explorer.exe shrinks to
normal 30-40MB usage and the one svchost is also small ~30MB working set. It
will be about 2-3 days before the system needs to be restarted once more as
it'll start becoming extremely slow/sluggish to use.

This only started after applying SP1. Prior, uptimes of >30+ days and the
system performed great. These systems are Home Premium, 32-bit and with 2
or 3 gigs of system ram each.

Any tips on trying to isolate what is causing explorer.exe to balloon so
much post SP1?

Hello.

For specific SP1 support, you can go directly to Microsoft for free. Here's the link: https://support.microsoft.com/oas/de...4&gprid=500921

There's a utility that will "defrag" your ram and make it usable again. Here's the link for the program: Crucial Memory Mechanic

I hope this helps.

Hi,

You might try using Process Explorer to get a better handle on precisely
what is causing the issue:

I have the SAME exact problem.

Find a fix?

Yeah, I noticed that this issue was dead...just a shot in the dark. Im disabling services one by one to see if I find the culprit.

I sincerely doubt that it's Vista.

What even makes you think you have a memory leak?
