Microsoft confirms XP right click memory hog problem

Yep, thats right. 3 weeks after we posted the original reposted finding on BugTraq and a day before The Inquirer stumbled across it. It's only fair to say that The Inquirer has beaten us to Microsoft's whisper of acknowledgment and a workaround for this bug, which is -yes, no different to the workaround we posted on 26th of April.

While Microsoft have issued no indication of a patch to correct this problem they have put up an article entitled: Temporary Decrease in Performance Occurs When You Right-Click a File or Folder in Windows Explorer. It appears to have been posted 3 days after our article.

Microsoft says in the note that when you right click a folder using Windows Explorer, the CPU usage flies up to 100% when the shortcut menu is displayed.

That means any file copy operation "may appear to stop responding", "network connection speed may significantly decrease", and streaming operations, like listening to music, can become distorted. I suppose its disappointing to see that a fix is in fact disabling (native) features but we can only hope this is solved in SP2 or a patch. Read more for the workaround.

View: Explorer 100% utilization in Windows XP (26 April 2003)
News source: The Inquirer

I've seen this before Rikytik,

On all my systems it does the same (all Intel).
But it does not on my P4 3.06 GHz HT enabled.
CPU utilization is 50 percent on one CPU.
The other about 25%

HT disabled and 100% CPU utilization.

:starwars:

What's HT?

The information in this article applies to:
Microsoft Windows XP Home Edition
Microsoft Windows XP Professional
Microsoft Windows XP Home Edition SP1
Microsoft Windows XP Professional SP1
Microsoft Windows XP Home Edition SP1a
Microsoft Windows XP Professional SP1a


WORKAROUND
To work around this behavior, use either of the following methods:

Turn off the transition effects for menus and ToolTips. To do this, follow these steps:

1. Click Start, and then click Control Panel.
2. In Control Panel, double-click Display.
3. In the Display Properties dialog box, click the Appearance tab.
4. On the Appearance tab, click Effects.
5. In the Effects dialog box, click to clear the Use the following transition effect for menus and tooltips check box, and then click OK two times.

HT = HyperThreading.

Makes the comp think its 2 cpus, even though its 1, and its runs faster

He asked what is HyperThreading, now what does HT stand for. :P j/k

Hyper-Threading Technology is a groundbreaking innovation from Intel® Corporation that enables multi-threaded software applications to execute threads in parallel. This level of threading technology has never been seen before in a general-purpose microprocessor. Internet, e-Business, and enterprise software applications continue to put higher demands on processors. To improve performance in the past, threading was enabled in the software by splitting instructions into multiple streams so that multiple processors could act upon them. Today with Hyper-Threading Technology, processor-level threading can be utilized which offers more efficient use of processor resources for greater parallelism and improved performance on today's multi-threaded software.
Hyper-Threading Technology provides thread-level-parallelism (TLP) on each processor resulting in increased utilization of processor execution resources. As a result, resource utilization yields higher processing throughput. Hyper-Threading Technology is a form of simultaneous multi-threading technology (SMT) where multiple threads of software applications can be run simultaneously on one processor. This is achieved by duplicating the architectural state on each processor, while sharing one set of processor execution resources. Hyper-Threading Technology also delivers faster response times for multi-tasking workload environments. By allowing the processor to use on-die resources that would otherwise have been idle, Hyper-Threading Technology provides a performance boost on multi-threading and multi-tasking operations for the Intel® NetBurst? microarchitecture.

This technology is largely invisible to the platform. In fact, many applications are already multi-threaded and will automatically benefit from this technology. However, multi-threaded applications take full advantage of the increased performance that Hyper-Threading Technology has to offer, allowing users will see immediate performance gains when multitasking. Today's multi-processing aware software is also compatible with Hyper-Threading Technology enabled platforms, but further performance gains can be realized by specifically tuning software for Hyper-Threading Technology. This technology complements traditional multi-processing by providing additional headroom for future software optimizations and business growth.

Hyper-Threading Technology offers many benefits to e-Business and the enterprise such as:

Enables more user support improving business productivity
Provides faster response times for Internet and e-Business applications enhancing customer experience
Increases number of transactions that can be processed
Allows compatibility with existing IA-32 applications and operating systems
Handles larger workloads
Offers headroom for future business growth and new solution capabilities

Awesum tip, Fisher..You just solved a problem that has been driving me nuts lately!

And I am using a 3.06 HT machine, with a gig of memory!!

What a great place BetaOne is!

Good tip people...fixed a nagging problem I have been having.

Thanks Fisher for this tips ;) I will save it since the SP2 final will be out :lol:

thx guys !
