Hello dear readers.
Today I would like to talk about a tool that practically no computer can do without - a mouse. This equipment is simple in itself. In almost 99% of cases, it works without any problems. But sometimes some users still run into problems. Due to the fact that the device is usually installed by the system on its own, many do not know how to update the driver for the mouse - most often this is what helps to restore functionality. I must say right away that this procedure is simple and does not require any serious knowledge.
The mouse driver for Windows 7 or any other version of the operating system is a small program that allows the Mouse to interact with the system. Timely updates improve performance, reduce responsiveness, and prevent potential disruptions. Using old or somehow damaged drivers leads to OS errors and even complete hardware failure. And installing the wrong ones can make the whole situation worse.
Main problems and solutions( )
If you are faced with a situation where the mouse does not work, regardless of its manufacturer, you need to try a few simple movements to find out the reason, and then try to eliminate it:
Sometimes there are situations when the corresponding component is not in " Device manager". Don't panic - let's look elsewhere:
Self-installation( )
Sometimes there are situations when it was not automatically possible to connect the equipment. Then we try to download the driver to our computer and install it manually. Typically, this approach is needed for devices that are equipped with more than two buttons and a wheel. In most cases, they are designed for playing games and performing some complex tasks.
Today the most popular manufacturer of mice is A4tech, and therefore I will tell you on its example. In addition, it offers users keyboards, headphones and other related equipment. They even have full-fledged episodes, for example, fornication. The X7 mice are especially popular.
Regardless of the model, go to manufacturer's official website and find a link leading us to the related software. After that, we select a driver based on the device model, operating system and its bitness. Download the package and run it. Using the prompts, install the component. Sometimes you need to reboot. It is worth noting that you can do the same with equipment from HP, Samsung and others.
Well, despite the fact that the manipulator “ Mouse"Is a simple device, but certain problems may arise with it. Their solution does not require any serious skills or knowledge.
Subscribe, and I will share with you many more interesting things.
Experts estimate that with an 8-hour work shift, a person wasted up to 64 hours a year if he performs most of the tasks with only the mouse. To perform monotonous actions, you can use short key combinations, and not climb the entire screen with the mouse.
Fast system lock
It often happens that you move away from the computer, and at the same time want to hide the screen from prying eyes. It turns out that the PC can be quickly locked by using the Win + L combination. On Apple MacBooks, the Cmd + Alt + Eject combination is used for this. When you return to work, the PC will ask you for a password to enter the system.
Instant browser tab restore
When searching for any information on the Internet, it sometimes happens that we close the tab, and then we realize that there was something important on this page. In addition, the desired tab sometimes closes accidentally instead of another page. To restore it, you don't have to go into the browser menu and dig into the site history for a long time: just press the Ctrl + Shift + T keys. On MacBooks, enter: Cmd + Z (if you are working in the standard Safari browser), and in Google Chrome it is already used the familiar Ctrl + Shift + T shortcut.
Computer freezes
Perhaps all computer users are familiar with the situation when a program freezes or the entire system slows down. In this case, you can try to forcibly close the problematic application using the Task Manager.
Do not try to find the Dispatcher in the programs or PC settings; there is a special command to call it: Ctrl + Shift + Esc. On Mac, you need to press the complex combination Cmd + Option + Shift + Esc.
After the Dispatcher appears, find the braking program in the list and disable it using the "End task" button.
Juggling windows
When the user switches between windows, he has to constantly go down to the taskbar, find the required window and select it. The short command Alt + Tab (Cmd + Tab on MacBooks) will instantly switch between active windows. If more than 2 programs are open at the same time, they will be scrolled in sequential order.
Fast address saving
When we need to save some important link, we manually select it in the search bar by moving the mouse cursor for a long time. In fact, it is enough to press Alt + D (in some browsers Ctrl + L), so that the address is immediately highlighted. On Apple devices, the Cmd + L combination is assigned to this operation. Now this link can be copied using the more well-known Ctrl + C command.
Minimizing windows quickly
Sometimes the user needs to find something on the desktop, and for this he closes or minimizes all active windows for a long time. It so happens that you simply do not want to show someone open applications, and try to go straight to the desktop. The short command Win + D (on Mac use Fn + F11) instantly minimizes all windows and programs, leaving only the desktop.
Screenshot of only the required screen space
Another important procedure is the creation of screenshots, because often this is the only way to show someone the information you need. A screenshot is taken using the Print Screen (PrtSc) button, after which it is inserted somewhere (for example, in Paint) and the required area is cut out.
The operation can be significantly accelerated by pressing the Alt + PrtSc keys. After that, the system will only save the image of the active window. On MacBooks, use the command Ctrl + Shift + 4, then press the spacebar and select the required window.
Telegram is one of the most popular instant messengers in the world. Everyone has their own reasons for using it. It is worth highlighting the advantages that distinguish it from other communication applications.
Telegram channels as an alternative to VKontakte publics
Originally Telegram was a chat and correspondence application. After a while, channels appeared in it. Unlike groups on the Vkontakte social network, they broadcast unilaterally and are somewhat reminiscent of the media. Each channel has administrators who send messages to subscribers, and a link through which you can get to this channel.
Large set of stickers
It is no longer possible to imagine modern communication on the Internet without stickers. Stickers are pictures that do not have a background and convey emotions and feelings. They can replace words, phrases and whole sentences. They are free on Telegram, unlike many other apps. In addition, using the special @Stickers bot, you can create them yourself and even share them with your friends.
Possibility to pin chats
Telegram has the ability to pin important contacts, channels and chats at the very top of the feed. This is done by long pressing on the element that you want to pin. This action will bring up the menu at the top and in it you have to click on the image of the safety pin. After that, the pin will be displayed to the right of the channel or chat name.
Saved Messages
The Saved Messages feature allows you to save messages, files, links and documents up to 1.5 GB in the cloud storage. It looks like a chat with itself. You can open it in the side menu by clicking "Favorites".
Secret chats
Secret chats are one of the reasons why people in Russia are trying to block the work of Telegram. In them, it is impossible to track and intercept the information being sent. You can even customize the period of time after which everything you write will be deleted. If the interlocutor turns out to be smart and makes a screen with your messages, then you will receive a corresponding notification.
To start a private chat, open the side menu and select "Create Secret Chat". After that, a list of contacts will open, where you will need to select a recipient.
Convenient message editing
To edit your Telegram message, tap it and select "Edit" in the menu that appears. After all the changes, confirm your actions by clicking on the blue checkmark on the right. Now the interlocutor will see only the corrected version of the message.
Find messages from a specific person
Search is well implemented in the Telegram app. With it, you can find not only the right person, chat or channel, but also messages. It often happens that in a general chat there are more than one hundred people constantly writing something. To find messages from a specific person, you just need to type in a username that starts with @.
Telegram bots to simplify work in other services
Bots are now in many messengers. However, in Telegram, thanks to its relevance, their number is increasing with amazing speed.
A bot is an algorithm that executes pre-written commands in it.
For example, there are telegram bots that create memes (@memingbot), spell checkers (@fixmebot), choose a winner by likes on Instagram (@getlikersbot) or download music from Vkontakte (@audiobot).
Delete messages for everyone
Telegram allows you to delete your message from a group chat so that it disappears from devices for all users. It is possible to delete the entire dialogue entirely, which will not allow third parties to even logically guess what topic the correspondence was on. To do this, open the desired chat and go to its menu: three dots in the upper right corner. Select "Delete chat", and when the application asks you for confirmation of actions, check the box next to "Also delete for<Имя собеседника>».

A driver is essentially a link between the operating system, that is, software and hardware, that is, physical devices such as video cards, printers, processors, etc. The operating system can contain basic drivers for the most necessary devices - a mouse, a keyboard, but for everything else, fresh drivers are required.
