Evaluates Windows 7 performance index. What is the performance index

In windows 7 there are very interesting functionthat evaluates the capabilities of your computer based on the hardware and software configuration. It is a pity that it can be used after purchasing a computer, and not before. And seriously, this feature is called the "Windows 7 performance index". Let's deal with what it is.

What and how is it?

First of all, the main components of the computer are tested for performance - cPU, Winchester, RAM (RAM) and graphics. To obtain an estimate, click "Start", "Control Panel". In the large list we are looking for "counters and productivity means". Press.

If you have not yet used this feature, you will see the "Rate Computer" button in the lower right corner. If the operation has already been carried out, then the previous WINDOVS 7 performance index will be reflected in the zkrane. To update, click "Repeat the rating".

During the performance estimate of the computer performance, you should not run any programs. Upon completion, a window will appear with the results.

What do these numbers give?

Estimates are exhibited on a scale of 1.0 to 7.9. Approaching the base index to the top mark indicates the power of the computer. Do not think that the base index is averaged value of the data. This is the smallest of them. In our case, the processor was estimated to be 5.1, the memory is 5.5, the graphics 4.3, the hard drive 5.4. From this, the base index 4.3 was obtained.

Obviously, to increase computer performance, it is necessary to either update morally outdated components, or competently configure those components that have received a low estimate. In our case, it is graphics.

What can be changed?

The question arises: "How to increase Windows 7 performance index"? First you need to independently optimize the operation of your computer. To this, we will take at least the following list of actions:

• disconnect visual effects
• disable unused services
• spend check hard disk for errors and broken clusters
• make disk defragmentation
• clean your computer from unused files.

Update the Windows 7 performance index - in 99% of cases, the above-mentioned actions will be praised on its indicator. If nothing changes, update the versions of the drivers of your equipment. You can use ready-made programs to optimize the system, such as Tuneup Utilities or Windows 7 Optimizer. All in your hands!

We recently spoke in detail about. Value Windows Experience Index All degrees to some extent to evaluate the configuration of the hardware of a particular computer. The higher the performance index, those in theory, should be higher than the performance of the computer. When buying a new (or used) computer, many inexperienced users (weakly disassembled in modern computer hardware) Can be focused on the value of the performance index. In their opinion, it allows you to compare different configurations with each other. In this article we will show that it is impossible to do so, because the values \u200b\u200bof the performance index can be simply enough to increase, and, naturally, it will not affect the actual performance of the computer.

The current performance index value (Windows Experience Index) can be viewed in the System Properties window (Computer-\u003e Properties)

The data in this window is displayed based on the testing of various components with computer tests. The resulting values \u200b\u200bof the Windows performance index (WEI) are stored in the system as XML file., the contents of which can be simply modified.

That's how we turned our old computer in a supercomuter!

It is worth noting that such an increase in the rating of your computer can be a goal not to simply increase the CHVE with large cliquers. Some applications (first of all Aero, in various "decorated" systems and games), just do not run on a low rating computer. The fact is that such programs using the Windows Experience Index API when starting can check the current WEI value

To return the "true" value of performance index indicators, in the rating window " RE-RUN THE ASSESSMENT»

If the computer slows down, there are problems using programs or video viewing - it makes sense to check the performance of the computer. The performance index is used by the Windows 7 operating system for visual and understandable assessment of your own work. Than he is higher - the faster and more powerful computer, the more difficult programs and games it will pull.

What is the performance index

Windows Performance Index (Windows Experience Index, WEI) - Operating Service windows systemsallowing a computer performance test.

How to learn productivity index

To find out the performance index, there are several ways. Consider the two most simple.

Through "My Computer"

Through the "Start" menu

As you can see, both ways are simple enough and do not take much time.

Which categories are presented in the table

The "Productivity Index" table includes five components:

What are the numbers mean

WEI computer is determined by the smallest rating. The maximum value of points in Windows 7-7.9, minimum - 1.0. Consider the indicators of the "performance index" on the example of graphics evaluation.

Table: Publicity Index scores and computer functions that match them

Methods for improving computer performance

For modern desktop computer The normal performance index starts from 5.0. Note that on graphic devices you need to install fresh driversOtherwise, indicators can be understated.

Most often, WEI will be equal to 5.9 when using HDD ( hard disk), even if the estimates of other categories are much higher. This is explained by the low rate of appeal to the main hard disk. When replacing hDD disk on the solid State SSD Evaluation of the hard disk is rising to 7.9 and becomes the highest in the category table. The use of solid-state disks improves significantly windows work generally.

Low graphics indicators may be the result of absence graphic drivers or insufficient video card performance. To correct the software, you should download drivers from the manufacturer's official website, which has released graphic equipment to your computer. If the drivers are installed correctly, improve the performance index will help replacing the video card to more powerful.

Additionally, computer performance can be increased by the following actions:

What to do if the performance estimate does not work

It happens that the procedure for calculating the performance index ends with an error. This error can be caused by both software and hardware problems.

Software problems:

• availability in the system of viruses, trojans, malicious programs;
• disk errors;
• errors of paths or registry.

Refusal or hardware problems incorrect work One of the elements.

Software errors are solved as follows:

• verification of a computer with antivirus (MalwareBytes), as well as other antivirus utilities;
• check hard disk for errors;
• scanning system for damaged components. To do this, open the command line on behalf of the administrator and enter the SFC / SCANNOW command, press ENTER. The system will automatically check and whenever possible will be corrected damaged system files;
• install K-Lite Kodeck Pack;
• restoring the system, if anything helped (refund of the computer to an earlier state - when everything worked, - with the help point).

In suspected problems with iron it is necessary aIDA program Check the temperature of the sensors - eliminate overheating. Checking contacts, checking RAM memory for errors (for example, MemTest86 program), the video card stress test will help identify or eliminate the problems in the work of any component. If you are not sure that you should cope, it is advisable to contact a specialist, since the wrong tests can lead to a breakdown of the computer.

Often an error calls a computer power supply. Since when calculating the performance index, all items work under the maximum load, it may not be enough power. If this is a laptop - check the power settings, there must be "maximum performance", and it itself should be connected to the network at this time. If problems are eliminated in the components, it may be time to replace the power supply to more powerful. Even the working unit of the power supply after a year of continuous use loses the power, which is why equipment failures arise and " blue screen of death".

The "Windows performance index" (WEI) folds from several factors: processor power, speed random access memory, performance 2D and 3D graphics and data exchange rates with hard disk. The overall assessment is determined by the smallest indicator. To enhance Wei, there are several ways, among which is to replacing the video card or hard disk, and cleaning, check for errors, etc. If the performance estimate does not work, then you should check the computer to viruses or find errors in the registry. Also, the cause of problems can be problems with the video card or computer power supply.

Bought a new laptop, installed Windows 7., everything works, but making an assessment performance Appears error And the assessment stops. On the Internet, there are many information and methods for solving this issue, but unfortunately having done them all the problem and remained.

I will give, in my opinion, examples of solving this problem that you will be able to help, but a little lower I will describe that all the same helped me.

So, let's begin:

Delete from the folder Windows \\ Performance \\ Winsat \\ Datastore \\ All files with extension .xml, Launch command line on behalf of the administrator(Start-to-enter in the Find CMD field, cmd.exe will be displayed in the search results, click on it right-click Mouse-start on behalf of the administrator), enter and execute the following commands sequentially:

-sfc / scannow
-Secedit / Configure / CFG% WINDIR% \\ inf \\ defltbase.inf / db defltbase.sdb / verbose
-Winsat Formal

(True, after the command Secedit writes: an extended type error. The job is executed with an error. Details are recorded in the log of% windir% \\ Security \\ Logs \\ scesrv.log.)

Restart your computer, try to assess again.

-Winsat Formal Performing a formal productivity assessment of problems did not occur. Ie B. command line The performance assessment was successful, and when it tried to evaluate through the properties of the computer, an error appeared anyway.

I found another solution option:

Good afternoon! Just decided this problem - snove all codecs, rearranged Windows Media Player. (Go Start - Control Panel - Programs and Components - Enable or Disable windows components, remove the mark with Windows Media. Player, restart the computer. Open the components again, set the WMP mark and restart the computer)
The problem appeared after installations KMPlayer and Codetes of the USSR.

Also did not help the option. Codecs were not at all, but removing KMPlayer. I still did not solve the problem. Reinstalling Windows Also did not help. Moreover, as 32x, 64 bit tried.

Then I found information that such a mistake could cause Kaspersky Anti-Virus, but the error was on a clean system without software at all.

And one of possible solutions Problems:

The problem is that K-Lite or then deleted or something else that the standard decompressor on VC-1 and everything you need to do is not installed K-Lite Codecs - install, if already installed - go to the setting Ffdshow., or rather - Start - K-Lite Codec Pack - Configuration - FFDShow Video Decoder - and in the first section Codecs We are looking for VC-1, in his field will stand disabled., change on libavcodec. And OK, in general, everything \u003d)

But unfortunately it did not help it either!

A specific solution that helped me:

Laptop model on which this error was ASPIRE E1-572G.Downloaded driver for video card with http://support.amd.com/en-us/downloadeverything works, but when evaluating an error to do not do.

Always download drivers not a separate device manufacturer, namely the driver from the laptop collector.

We go to the site http://www.acer.ru/ac/ru/en/content/drivers.

Choose search by laptop model. In the search results, we choose the necessary OS and the bit. As a result, we get a list of all necessary drivers It is optimized for the work of a particular laptop.

And as soon as I installed the drivers VGA FOR. AMD Radeon. R7 M265 / R5 M240,restarted the laptop although the system did not ask for it. And the performance estimate immediately passed without problems!

I hope the material will be useful!

Let's immediately we will evaluate the performance of Windows 7, and then we will analyze what it is and how to use it. For a more correct assessment, it stands in terms of food to put a tick - ( start - Control Panel - Power Supply - High Performance) And for a while turn off the antivirus and firewall. You should also close all working applications.

Start - Control Panel - System

And press the inscription in blue System estimate is not available

if you have previously done performance assessment, you will see the inscription under the table repeat estimates. If not checked, then press the button rate computer.

After a couple of minutes, it depends on your iron, you will see the processor performance estimates, RAM, video cards and a hard disk.

Now let's arrange a small palace analysis.

The maximum assessment that can be obtained in Windows 7 - 7.9 points.

The I7-2600 processor with a frequency of 3.4 GHz is slightly outdated and not exposed to no acceleration, score 7.7 points, which is not bad in principle.

RAM 16 GB Corsair Dominator with a frequency of 1866MHz and timings 9-10-9-27 works out with a bang!

Video card NVIDIA GeForce. GTX-670 also taxes with a bang (verified by tests and games)

As we see in the screenshot, the most narrow place in the system is hDD. An indicator of 7.6 points is in principle a fairly good result and all because the system is installed solid-state hard Disc - SSD. With good high-speed indicators, where the recording speed and read speed are the same. For conventional screws, performance rating does not exceed 5.9 points.

So we know our bottleneck in the gland, now, if you wish and financial opportunities, we know what we should upgrade. If you have not imprited your iron for a long time, then the best option Will sell the old computer and buy a new one. And in no case do not buy computers in "vegetable" stores. I mean, for such things there are specialized salons and shops, but not hypermarkets household appliances. Do not listen to the Council - attend.

Unfortunately, the price of SSD is quite high, and their capacity is still not reaching the size of the screws familiar to us, but something you can do something. About how to speed up the work of the computer in the next article soon.

By the way, if you are confident in your hardware, and the tests showed bad results, then watch: updates controller drivers, replacement motherboard, voltage checking in control points, monitoring device temperature.
