Hello dear readers.
Today I would like to talk about a tool that almost no computer can do without – a mouse. This equipment itself is simple. In almost 99% of cases it works without any problems. But sometimes some users still encounter problems. Due to the fact that the device is usually installed by the system itself, many do not know how to update the driver for the mouse - most often this is what helps to restore functionality. I’ll say right away that this procedure is simple and does not require any serious knowledge.
A mouse driver for Windows 7 or any other version of the operating system is a small program that allows the Mouse manipulator to interact with the system. Timely updating increases performance, reduces response time and prevents possible failures. Using old or somehow damaged drivers leads to OS errors and even complete hardware failure. And installing the wrong ones can aggravate the whole situation.
Main problems and solutions( )
If you encounter 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 fix it:
Sometimes there are situations when the corresponding component is not in " Device Manager" Don't panic - let's look for it elsewhere:
Self-installation( )
Sometimes there are situations when it was not possible to connect the equipment automatically. 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 just two buttons and a wheel. In most cases, they are intended for games and performing some complex tasks.
Today, the most popular mouse manufacturer is A4tech, and therefore I will tell you using its example. In addition, it offers users keyboards, headphones and other related equipment. They even have full series, for example, fornication. X7 mice are especially popular.
Regardless of the model, go to official website of the manufacturer and find a link leading us to the accompanying software. After that, we select the driver based on the device model, operating system and its bitness. Download the package and run it. Using the prompts, we install the component. Sometimes you need to reboot. It is worth noting that the same can be done with equipment from HP, Samsung and others.
Well, despite the fact that the manipulator " Mouse" is simple device, certain problems may still arise with it. Their solution does not require any serious skills or knowledge.
Subscribe and I will share many more interesting things with you.
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 may contain basic drivers for the most necessary devices- mouse, keyboard, but for everything else you will need fresh drivers.
How to install the driver?
1.The easiest way, if available installation file, then you just need to run it and follow the installer's instructions.2.If there is no installer available, and there are only files with the extensions *.inf, *.dll, *.vxt, *.sys, *.drv., then the algorithm of actions should be approximately as follows:
a) First you need to select the icon ( My computer) and click on it right click mouse, select ( Properties).
b) Now go to the tab ( Equipment) and presses the button ( device Manager).
c) Now you need to select the device for which the driver will be installed/updated. On the line with the device, you need to right-click and select ( Properties), or you can simply double-click on it to go to the desired settings. 
d) Go to the tab ( Driver), select the button ( Update).
e) In the dialog box that appears, select the item ( No, not this time) and go to ( Further).
f) At this stage there are two options. You can try to install the drivers in automatic mode, then the OS itself will try to find drivers suitable for the device and install them, for this we select ( Automatic installation(recommended)) , if the attempt fails, then you need to move on to the second point ( Installation from a specified location) and select ( Further).
g) This menu item implies a choice between searching for a driver on removable media and the option to specify the folder with the driver yourself. Therefore, if you have a disk with drivers, you need to insert the disk into the CD-rom and select the option ( Search on removable media (floppy disks, CDs...)) and go ( Further).
If the driver is found and downloaded on the Internet yourself, then you need to manually specify the path to the folder in which the installation data for the driver is located as follows. Select the item ( Include the following search location:) and go to ( Review), now select the folder with the driver from the list and click on the button ( OK). Now we boldly move on ( Further), if everything is done correctly, the installation of the necessary driver will begin. 
Experts estimate that during an 8-hour work shift, a person wastes up to 64 hours a year if he performs most tasks only with a mouse. To perform monotonous actions, you can use short key combinations, rather than crawling with the mouse across the entire screen.
Quick 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 you can quickly lock a PC if you use the combination Win + L. On Apple MacBooks, they use the combination Cmd + Alt + Eject for this. When you return to work, the PC will ask you for a password to log into the system.
Instantly restore a browser tab
When searching for any information on the Internet, sometimes it 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 need to go to the browser menu and delve into the history of sites for a long time: just press Ctrl + Shift + T. On MacBooks you should enter: Cmd + Z (if you work in standard browser Safari), and in Google Chrome already familiar is used combination Ctrl+ Shift + T.
Computer freezes
Perhaps all computer users are familiar with the situation when some program freezes or the entire system slows down at once. In this case, you can try to force close the problematic application, for which you use the Task Manager.
Do not try to find the Manager in programs or PC settings; there is a way to call it. special team: Ctrl + Shift + Esc. On a Mac, you need to press the complex combination Cmd + Option + Shift + Esc.
After the Manager appears, find the slowing 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. A short command Alt + Tab (Cmd + Tab on MacBooks) will allow you to instantly switch between active windows. If more than 2 programs are open at the same time, they will be scrolled through in sequential order.
Quickly save an address
When we need to save some important link, we manually highlight it in search bar, moving the mouse cursor for a long time. In fact, you just need to press Alt + D (in some browsers Ctrl + L) to immediately highlight the address. On Apple devices, the combination Cmd + L is assigned to this operation. Now this link can be copied using the more well-known command Ctrl + C.
Quickly minimize windows
Sometimes the user needs to find something on the desktop, and to do this, he closes or minimizes all active windows for a long time. It happens that you simply don’t want to show someone open applications, and try to go straight to the desktop. A short command, Win + D (on a Mac, use Fn + F11) instantly minimizes all windows and programs, leaving only the desktop.
Screenshot only the required area on the screen
Another important procedure is to create screenshots, since this is often the only way to show someone necessary information. A screenshot is taken using Print buttons Screen (PrtSc), then paste it somewhere (for example, in Paint) and cut out the required area.
The operation can be significantly speeded up by pressing the Alt + PrtSc keys. After this, the system will only save the image active window. On MacBooks, use the command Ctrl + Shift + 4, then press the space bar and select the required window.

Unlike groups in social network“VKontakte”, they broadcast unilaterally and represent something 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
Modern communication on the Internet can no longer be imagined without stickers. Stickers are pictures that have no background and convey emotions and feelings. They can replace words, phrases and entire sentences. In Telegram they are free, unlike many other applications.

Secret chats

You can even set a period of time after which everything you write will be deleted. If the interlocutor turns out to be smart and takes a screenshot of your messages, you will receive a corresponding notification.

It often happens that in the general chat there are more than one hundred people constantly writing something. To find messages from a specific person, just enter the username that begins with @ into the search.
Telegram bots to simplify work in other services
Bots are now available in many instant messengers. However, in Telegram, due to its popularity, their number is increasing with amazing rapidity.
A bot is an algorithm that executes pre-written commands.
For example, there are Telegram bots that create memes (@memingbot), check spelling (@fixmebot), choose the winner based on 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 all users’ devices. It is possible to delete the entire dialogue, which will not allow third parties to even logically guess what topic the correspondence was about. 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 to confirm your actions, check the box next to “Also delete for<Имя собеседника>».
