Even the intermediate results of a program must be stored somewhere in order to be used. The most necessary ones are in RAM, from where they quickly enter the program cycle wheel and are used for further calculations. RAM is limited, there is little of it, and it is needed constantly, so it is constantly cleared. And some of the information that is still needed in the future is saved in files and stored on the computer’s hard drive. Such files are called temporary. They accumulate, take up space, and need to be removed so they don't interfere with your computer's operation. So what are the best ways to clear the cache in Windows 7?

What is cache memory on a computer?

The cache memory stores the most important temporary files that may be needed in the near future. For example, when you watch a video on the Internet, it is gradually downloaded and stored in the browser's cache until you finish. Then the video is deleted as unnecessary. So, in essence, even if you include a movie on the Internet, you still download it to your computer and delete it after watching it.

Cache memory is also used in Windows. Usually the results of program calculations are stored there. Usually the cache is deleted in a timely manner, but there are types that accumulate and clutter the system because the computer cannot determine whether this information is still needed or no longer needed. There are four types of cache that need to be cleared regularly.

  1. DNS cache, which stores the computer's requests to other servers on the network. Necessary in order not to waste time on repeated calls, all necessary information is stored in cache memory. When you need to completely update the data from the server, then the DNS cache also changes. Accordingly, the data is not deleted by itself, so even unnecessary data is stored there.
  2. Thumbnail cache. Thumbnail literally translates as “thumbnail”, and figuratively means English language thumbnail pictures, previews or sketches. The computer stores icons of pictures, video files or program icons in cache memory, so it loads the thumbnails the second time much faster. But if the pictures themselves have already been deleted, their thumbnails do not disappear from the cache.
  3. RAM cache. The RAM itself also stores temporary files using cache technology. And some files are not cleaned due to errors or bugs.
  4. Browser cache. We've already mentioned caching videos for online viewing, but that's not all. Every picture, design element, and animation on websites is saved in cache memory. Some web pages are stored entirely in temporary memory to reduce loading time. All this accumulates, and even sites that are no longer used continue to take up space.

DNS

DNS (Domain Name System, literally - domain name system) is a kind of Internet address book. The fact is that the computer will not be able to find using symbolic addresses (such as yandex.ru) required server, to which he must contact. The computer only understands the language of IP addresses. DNS servers, of which, by the way, there are a lot, store the correspondence between IP and letter address. A user entering a query into a search engine or address bar, sends a signal first to the DNS server, which finds the corresponding IP address and sends it to the computer so that it can load the desired web page.

The DNS cache is cleared using the command line. To open it, press Win + R (Run program) and enter cmd in the field. Or open Start, go to Accessories and launch Command Prompt.

At the command prompt, enter: ipconfig /flushdns

The line “Successfully reset the DNS resolver cache” will appear. DNS cache cleared.


Enter the command ipconfig /flushdns

Nuances for RAM

Since the RAM cache should be cleared regularly, it makes sense to make the process easier. Let's create a shortcut that will send us to a program that cleans temporary files. So click right click mouse on an empty space on the desktop and select “Create” from the menu, then “Shortcut”. Now find out the bitness of your system version (open “Computer”, right-click on free space, select “System Properties”, and it will indicate: 32- or 64-bit system).


Enter a line depending on the bit depth of your OS

Depending on your version, enter one of the following lines in the field:

  • For a 32-bit system: %windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks
  • For 64-bit: %windir%\SysWOW64\rundll32.exe advapi32.dll,ProcessIdleTasks

Click Next, name the shortcut as you wish, and save it. Now, every time you run this shortcut, the system will analyze the software processes and delete the unused part of the RAM. In the long run, regular cleaning will help improve the performance of your computer.

Surely you have often heard the phrase - clear the cache. Allegedly, this will increase the speed of the computer. This is true to some extent, but what is the Windows Cache and where can I find it? The word itself comes from the English verb cacher, that is, “to hide.”

Therefore, we are talking about files that are securely hidden from the user’s eyes. That’s right, you need to go through a lot of folders to clear the entire cache of a computer running under Windows control 7, XP or other version. But there are simpler ways.

General concepts

There are at least 4 types of cache:

  • browser-based;
  • file thumbnails;
  • RAM (random access memory).

In addition, some programs may create their own temporary files during their operation. To remove them, just clear the RAM CACHE.

Before we begin to consider cleaning methods, it is worth answering the question - what does removing these invisible files? In most cases, the browser cache, for example, is a huge number of small files that accumulate during computer operation.

We looked at the online video and it is already in the cache and will be there until a reboot or manual clearing. We launched the game and it took up most of the RAM. But when you leave the game, part of it may remain occupied. It's the same with some programs. In this case, the RAM may not be enough for other tasks. And on the hard drive, temporary files without cleaning begin to take up gigabytes of memory for a long time.

Why endure this when you can clear the cache quickly and easily?

Copy the command into a new window:

%windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks

and execute. Memory cleared! For 64-bit Windows, use this command:

%windir%\SysWOW64\rundll32.exe advapi32.dll,ProcessIdleTasks

Methods for DNS cache

We are talking about stored data regarding computer requests to Internet servers. If you want to completely clear this history, follow these simple steps:

  • Open Start.

On the “Advanced” tab, enable the “Optimize the operation of services in background" and "Optimize the system cache." After applying the settings, the capabilities of the system cache will be increased, this will help reduce memory load and speed up the launch and operation of some applications.

Change the paging file value on the same “Advanced” tab in “Performance Options”. This is the current size of the system cache, which stores information about the operation of applications. By default, the system automatically specifies the appropriate paging file value, but if your computer has weak RAM, you can increase this parameter doubled. At large quantities RAM, the paging file can be completely disabled. This will speed up the work system applications.

Increase the cache in your Internet browser, which stores information about previously loaded pages and other elements, which leads to faster opening of them later. For example, in Internet Explorer you need to go to Internet Options, then to Browsing History and click Options. Set the appropriate cache size in the Temporary Files and Logs Options window. In the Firefox browser, select the “Advanced” tab, then “Network”. Select "Disable automatic cache management" and set the options as desired. In Opera, cache settings are edited in the History window on the Advanced tab in the browser settings.

note

Sometimes the browser cache becomes full of unnecessary information, causing the application to slow down. Clear the data before closing the program by clicking the appropriate button in the cache settings.

Buffering (from English buffer) is the organization of data exchange, in particular input/output of information in computers and other computing devices. This implies the use of temporary storage of clipboard data. When entering data, some processes/devices write data to the buffer, while others read it. When outputting, everything is the other way around, respectively. The issue of increasing buffering directly comes down to increasing the buffer size.

Instructions

The clipboard is a place in the RAM (random access memory) of the computer where data is copied for temporary storage, for example, when working in the Explorer application or text editor. The buffer can be increased by expanding the paging file or by installing programs that expand the buffer's capabilities.

Increase the swap file. To do this, right-click on the “My Computer” shortcut on the desktop or in the “Start” menu. Select "Properties" from the drop-down menu. Next, go to the tab called “Advanced”, left-click on the “Performance Options” tab and click on “Change” in the “Virtual Memory” tab.
