When installing or removing applications from our computer, we must always bear in mind that as the number of installations increases, team performance is decreasing, since with each installation the Windows registry is modified so that the application is "coupled" to the system.
When it comes to removing applications, three-quarters of the same happens, since the process again includes editing the Windows registry and if the process is not done well, we can have problems in the long run with running our copy of Windows. If we want to prevent users who use our computer from dedicating themselves to installing and deleting applications, then we will show you a little trick.
And I say trick, why no need to install any third-party app on our computer to be able to block the installation or removal of applications. To avoid and these types of problems that always affect the performance of our computer, the best we can do is create user accounts for everyone.
Windows allows us to create accounts for adult users (administrators), without any limitation, or accounts for minors, accounts that allow us to modify the aesthetics of Windows, at least of its specific user without altering the operation of the administrator account.
Guest user accounts, which are not administrators, by default they do not have the option to delete or install applications of the hard disk, so if at any time you want to install an application that you really need, you will have to count on us, due to the limitations of your account.
For that, no need to log out in your user account, since before starting the installation, we will be asked for the password of the system administrator, without which it will be impossible to install in that user account.
