How to uninstall Windows 7 from a computer. How to uninstall Windows 7 updates from your computer

As you know, the operating system "Windows" should be updated at least every 12 months. And no matter how powerful your computer is, still in a year it will buggy, hang or "make off". Perhaps it's all about the viruses that live in the system, and their antivirus does not recognize them. But most often the "operating system" itself is getting old along with the drivers and all the other programs. One solution is to uninstall and install the new OS on the computer. How to remove Windows 7 from your computer and install a new one, you will learn in the course of this article.

About reinstallation

So, let's say you have a computer that suddenly started to bugger. If the limitation period for OS installation is more than 6 months, it is best to install a new one in its place. To do this, you will need an image of Windows 7. Here you have two ways - to purchase the original or to download the "pirate". Both methods are almost identical - the first is more reliable, but expensive, the second is absolutely free, but not the fact that exactly what you want is established. Also, you should carefully see if there is a license key for this image. If it does not exist, or you simply forget to rewrite it to a notebook, you will not be able to fully install the Windows on your computer. But all other files remaining on the drive "C" (where the OS is installed), will disappear when uninstalling.

And what about a laptop?

If it's a laptop, you can look at the back of the operating system. In the case of the "pirate" such cunning will not work. Here you need to pre-record the key and enter it separately during installation. If the label on the back of the laptop is erased, you can find the password on the web.

How do I uninstall Windows 7 from a computer if you do not have the original installation disc?

The absence of an original installation disc is not a problem for an advanced user, because you can download a pirated version of the "original" iso of the "Windows" image on virtually any relevant website. If you want to remove Windows 7 from a computer, remember that the "pirate" key can go different, so be very careful - write down the password that is indicated along with the link to the archive from the OS.

Now download the program to burn the image to disk. To do this, you can use the utility ImgBurn. After it is downloaded, install it on the PC, take a blank DVD + R (or RW - it does not matter) and insert it into the rum. After that, open the recording program, click Browse and select the "Windows image" item. Press "open", set to the minimum speed and wait for the utility to write the file.

Next, you will see a window with information that the disc was successfully recorded. Press "OK" and remove DVD + R from rum. Do not be scared if the disc will leave automatically automatically after recording - the program is arranged like this. The first step is completed. Now on how to uninstall Windows 7 from your computer.

Now we use the arrows on the keyboard to get to the "Install" and press the input.

In this case, when the window with the "License Terms" appears (this is approximately 5-6 minutes after pressing "enter"), check the box there. Then, press the enter key again.

Select the item "Full installation", select the installation disc with the recorded image. Click "Disk Setup" - "Format". This is where the main thing begins - all files that were previously on the local drive "C" are uninstalled. How do I uninstall the second Windows 7?

Helpful advice

For 12 months of working with a computer, each of us accumulates a lot of files and information that we store on drive "C". Therefore, to see them again after the "resuscitation" of the OS, copy them all into a safe place. This place can be either a USB flash drive or a local drive "D", files in which are not deleted when reinstalling "Windows". As practice shows, the latter option is more convenient and simple, since a flash drive often does not have enough free space for your data. Therefore, move all important documents to disk "D". And for the future, install all the programs there and store all the files, and output shortcuts to the desktop. So there will be much less trouble when installing new drivers, programs and everything else.

Uninstalling "Windows"

How do I uninstall Windows 7 from a computer? After clicking the "Format" button the system will automatically clean the "C" disk from all files - necessary and unnecessary, old and new.

In any case, no action is required before the disk is formatted.

When the disk formatting is finished, you will see a window with fields for entering the user name on the screen. Here we need to enter a name, a password (optional) and a product key. If you accidentally clicked "Next" and did not enter the key, the computer will ask you to enter it again, but a little later. Now you need to choose one of the three items for the update. You can choose any, but, as practice shows, the first one will be the most suitable.

We define the time zone and wait for a few minutes until the window with "Windows 7" appears on the screen.

The main thing is to copy all the important files and folders to the local disk D in advance, otherwise all of them together with the operating system will be irretrievably deleted.
