An issue that may have arisen is when we have at our disposal an iso with a language different from the one already installed in the system that we want to upgrade.

Even with the installation of a language change package it is not possible to upgrade in this way.

For a home user this may seem redundant and ends up downloading the iso in the requested language, but for a technician it is a challenge to solve, especially in a business information environment where he wants to save resources when he has to work on hundreds of computers. .

The following solution is given on the internet:

In the Windows registry in the path:
HKEY_LOCAL_MACHINE \ SYSTEM \CurrentControlSet \ Control \ Nls \Language
with the help of the link
[MS-LCID]: Appendix A: Product Behavior | Microsoft Docs
find the code corresponding to the language of the installation and change the value of the string InstallLanguage to that of iso.

So far, this solution allows us to overcome the upgrade prevention due to a different language, but it shows us the following option:

As we can see, it allows only the files to be stored in the user folder and not the installed applications.

If you do search στο διαδίκτυο θα δείτε ότι δεν υπάρχει λύση στο να διατηρηθούν και οι εφαρμογές για την περίπτωση που εξετάζουμε.
The solution is presented for the first time in iGuRu.gr and is as follows:

In the register along the way:

HKEY_CURRENT_USER \ Control Panel \ Desktop \ MuiCached \

We change the value of the string MachinePreferredUILanguages ​​in that of iso. In our example from el-GR to en-US which is the iso we have.

When we perform the upgrade again we find that we are now given the option to maintain the applications as well

The above process can bring about changes in the language of applications and other features of the operating system and can also be used to "compile" the Windows environment.

Because this is the first time that this solution is published on the internet, we are at your disposal for any observation or assistance in its implementation.
