Really slow USB 2.0 transfer rate since installing SP1

[guileman]

HI, i just notice that my usb transfer is really slow around 11mb/sec for my usb stick and around 20mb/sec for my external hard drive.

I noticed this change right after installing SP1. (I'm on windows 7 ultimate 64bit.)

The thing is that it happenned in a particular moment, i was transfering files to my external hard drive the same day i installed Sp1 and in the beginning of the transfer the transfer speed was normal, around 60mb/sec.

Then my Internet security software (Eset Smart Security) tells me that a process has changed in i think it was taskhost.exe (i am not 100% sure but i know it was a windows process), it ask me do i accept it, i press ok accept the change and then i saw my transfer speed slowed down right away to something like 20mb/sec.

Does anyone knows the problem with that?

What should i do?

Thanks in advance

Hello

No don't have this problem in fact my backups run faster - not that they are that large but definitely quicker.

My prob is the IE function seems to be getting slower loading pages having to click again to get pages to load, and even my boot is getting stedaily slower.

Have run scans to see if I've picked up any little nasties but nothing so like you blokes am at a loss as to what is going on.

So does anyone have an idea what's the problem with the USB transfer rate being so slow?

I removed REmote Differential Compression and my spends have increased much.

 

[guileman]

Thanks, where do i remove this option?

 

[riotkayak284]

Control Panel/Programs/Add-Remove Windows Components

I can't imagine how remote differential compression can affect USB speeds. It is a dll that an application must explicitly use to synchronize files and as such USB copy doesn't use it and hence it isn't loaded.

Thanks!! Will try and give feedback right away

 

[guileman]

It works! Thanks alot.
So i wasn't crazy!
I guess this was a known problem if they made a fix...


Who made this patch?
Why does microsoft doesn't release an update themselves?

Be careful..... I smell virus or spyware.

Looks clean

The issue was detected by some guys at mdl forums, and eventually someone wrote a tool to fix that.

 

[guileman]

Eset says it's clean.

Plus they give you the source code and md5.

And i installed it and it works like a charm.
My usb transfer rate is back at around 70mb /sec
