This section will explain what you would need to do to modify in the files for use in 21H2to7.

basebrd.dll.mui.res

For any locales

1. From Windows 7 you would only need String 14 in the Table 1 from Windows 7 which is the copyright text. (PosReady uses a different year for the copyright string.)

2. If the locale you want to translate doesn't translate the SKU name then you can add the string tables from 4 to 25 by going to Action > Add from a Resource file (*.res,*.mui,*.dll,*.exe) ... and import those string stables from 21H2to7 En-US locale (Which is found in C:\Windows\Branding\Basebrd\En-US\Basebrd.dll.mui) or from the It-IT locale

For locales that have special branding

Certain locales (As an example the Fr-FR one) have a special localized branding instead of the default En-US one. So it will require more work to add those.

1. From Windows 7 you would need to extract all the images from basebrd.dll.mui and save them as bitmaps.

2. In your .RES basebrd mui file go to Action > Add from a Resource file (*.res,*.mui,*.dll,*.exe) ... and import all the branding images from basebrd.dll

3. After importing the images, replace the original 7 branding images with the localized ones (you can figure out which image goes with which ID with the resolution of the image. As an example Windows 7's ID 120 is equivalent to Windows 10's ID 122 and Windows 7's ID 121 is equivalent to Windows 10's ID 123)

4. After you're done adding the specific branding images. Go back to step 1 for any locales.

themecpl.dll.mui.res

For themecpl.dll.mui you need to import the string tables from ID 1 to 3, string tables ID 7 to 8 and string table ID 70 from Windows 7

With the following changes:

String Table ID 1

For ID 1 you need to add the String 8 which is a copy of ID 6

String Table ID 2

For ID 2 you need to add the String 26 which is the string for "Automatic"

String Table ID 3

For ID 3 you need to add the String 34 which is a copy of ID 32

String Table ID 8

For ID 8 you need to change the number of ID 116 (Which is frost) to ID 117 and add ID 116 and name it "Automatic" (You have to translate this as what your language calls automatic in Windows 8+)

themecpl7.dll.res

For themecpl7.dll.res it requires more work. You need to take the string tables 7 to 8 from Windows 7's themecpl and keep the "LANGUAGE LANG_LANGUAGE, AxA" as the locale you want to modify. As an example: the italian locale should have the string tables with x:1040 and have at the start: " STRINGTABLE LANGUAGE LANG_ITALIAN, SUBLANG_ITALIAN " as the example here:

For String table ID 8 you need to copy the exact same modifications as you did for themecpl.dll.mui.res

themeui7.dll.res

This dll requires the same initial step as themecpl7.dll.res so make sure you have that setup for IDs 51 126 127 132 that you took from themeui.dll.mui from a Windows 7 installation.

String Table 51

For String Table ID 51 you have to remove every string except for String ID 800 801 802 803 804 as shown here:

String Table 126

For String Table ID 126 it's almost the same thing as ID 51 but with IDs 2000 2001 2002 2003 2004 2013 2014 and the inclusion of ID 2015 as shown here:

Note: ID 2015 should have "Windows 7 (Dark)" as how Windows 11 has its dark mode theme named. As an example the italian locale names its dark mode "Windows (scuro)"

String Table 127

For String Table ID 127 you only keep ID 2016 as shown here:

String Table 126

For String Table ID 126 it's almost the same thing as the previous first two IDs but with IDs 2101 2105 2106 2109 2110 as shown here:

UserCPL.dll.mui.res

For UserCPL's MUI you have to copy String table IDs 3 4 7 69 to 72 74 to 77 from Windows 7 like here:

String Table 3

In String Table ID 3 you need to add String ID 47 from Windows 10's MUI

Shell32.dll.mui.res

For UserCPL's MUI you have to copy String table IDs 577 1948 1958 1967 2002 2327 from Windows 7, IDs 4 and 1914 from Windows 10 and Dialog ID 14352 from Windows 7 like here:

String Table 4

For String Table ID 4 you have to remove from String 60 the "SO" "OS" or the variation of "OS" that is near "build" like this (Take a reference how Windows 7 displays the build number and copy that closely like the examples under here):

The original Windows 10 version would've looked like this:

String Table 1914

String Table ID 1914 only needs an edit in String 30621 which replaces the 8.1+ Computer name back to what Windows 7 (Windows 8.0 as well) called it previously like shown here (String Table 577 ID 9216 we modified previously should be the way Windows 7 called the folder previously):

String Table 1967

From String Table ID 1967 we need to add back Strings IDs 31462 to 31465 from Windows 10's MUI:

String Table 2002

String Table ID 2002 is almost similar as Windows 7's but with the inclusion of Strings ID 32024 to 32027 which IDs 32024 to 32025 are taken from Windows 10, IDs 32026 to 32027 are clones of IDs 32016 and 32017.

windows.storage.dll.mui.res

For windows.storage.dll.mui.res we need to take String table IDs 567 577 1948 3212 which we are going to replace the resources inside of them with some we modified previously in shell32:

String Table 564

In String Table ID 564 we only need to replace string 9012 with String ID 9216 from 577 from our modified Shell32:

String Table 577

String Table ID 577 can be directly copied from our modified Shell32 MUI like here:

String Table 1948

String Table ID 1948 can be directly copied from our modified Shell32 MUI but we only need to keep IDs 31154 to 31156:

String Table 3212

String Table ID 3212 requires a modification to String ID 51378 which we are going to replace "Quick Access" with "Favourites" (Localized like Windows 7):

Explorer.exe.mui.res

For Explorer we only need to import Menu ID 205 and String Table IDs 438 and 439 from Windows 7 like here:

tipresx.dll.mui.res

For tipresx.dll.mui we only need to import String Table IDs 938 and 439 from Windows 7 like here:
