Many users who have installed the tenth version of Windows on top of the seventh, after some time using the system, often wonder how to switch from 10 to 7 "Windows". The reasons for this decision can be quite a lot. Perhaps the user simply did not like the system or was too complicated to master. Maybe the minimum hardware configuration does not allow you to use all the features of Windows 10 in full. But you never know what could be. Here, there is an urgent need to solve the problem of how to switch from 10 to Windows 7. For this, there are several ways that allow such a return, but not all of them are equivalent.
Basic methods of returning to the previous system
In principle, in comparison with previous modifications of the operating systems of the Windows family, the developers made sure that the user could return to the previous version of the OS if the new system does not suit him for some reason. True, there are not so many options.

In the simplest case, the question of how to switch from 10 to 7 "Windu" within a 30-day period is solved quite simply. In the system itself there is, so to speak, a “wired” tool for returning. On the other hand, after a month, this tool is deactivated, and you have to use other methods (restoration from a previously created image, if any, or a “clean” installation). For some laptop models, the problem of how to switch from 10 to 7 "Windu" on a laptop (if the "seven" was installed initially, and the "ten" the user installed on their own), is solved by using special sections of the boot menu in which you can reset to factory condition. But then we will consider general methods that can be used for all types of computer devices.
How to switch from 10 "Windows" to 7 using the standard rollback method?
First of all, before a month has passed since the installation or upgrade of the system to the tenth modification, the simplest method of switching to the previous version will be rollback using the system itself.
In order to solve the problem of how to switch from 7 to 10 in this case, go to the settings, select the update and security section there, and then go to the restore item in the menu located on the left panel. On the right side of the screen there will be a line to return to the previous system, under which you need to press the start button of the rollback process. After some time, the user will receive a “seven” with all the settings that were set in it before switching to the tenth version.
How to switch from 10 to 7 "Windu", if more than a month has passed: recovery from the image
If rollback by the standard method is not possible due to the expiration of a 30-day period, you can do otherwise.
But there is one main condition: in order to get a workable OS with all previously set parameters, it is necessary that an image of the system be stored in a logical partition or on removable media in advance. Here the question of how to switch from 10 to 7 “Windu” after a month of using “tens” is solved quite simply.
If you save the image on the hard drive, rollback can be done using the system. If you use a removable drive, you must boot from it.
Clean system installation
If none of the above options gives a result, you will have to perform a “clean” installation of Windows 7 from scratch. To do this, you need a distribution recorded on an optical or USB-drive.
But here it is important to pay attention to one caveat. Install a 32-bit "seven", if you installed "ten" with the architecture of 64 bits, without formatting the system partition will fail. If Windows 10 had a 32-bit architecture (x86), installing a similar seventh modification should not cause any difficulties.
Create bootable media
In order to install Windows 7 without problems, you can use not only official distributions.
For example, the official utility from Microsoft called Windows 7 Software Recovery has proven quite well. Among other things, the main difficulty in installing the system is that for the "seven" in this case you will need a license key. But getting around this point is quite simple. To activate, you will need to use the small KMSAuto Net program, although, by and large, this is against the law. However, for many users, this utility is the panacea that "cures" any Windows-system.
Conclusion
In conclusion, it remains to add that the problem of how to switch from 10 to Windows 7 is solved quite simply. But in order to use the official rollback tool available in Windows 10, you just need not miss the deadline for its active state. Otherwise, you will have to use the other methods described above. At the same time, there can be no question of saving parameters and previously installed programs or user files (unless, of course, system recovery is performed from a previously created image).
In all other cases (a “clean” installation and reset to factory settings), the user will receive a bare-footed system, so to speak, and user programs and applications will have to be reinstalled. If we are talking about files and documents, it is advisable to first copy them to either a logical partition other than the system partition or to removable media. No other way. No, even an ultramodern program for recovering deleted files, in most cases can not help.
