How to add language input method to offline Windows 11 22H2 computer

For this topic, Internet information seems a bit unreliable because language feature installation process is completely changed on Windows 11. 

Follow these steps.

Step 1

Download Windows 11 Languages and Optional Features, version 22H2 iso file from your Visual Studio Subscription page.

 

 

Step 2

Mount downloaded iso using Windows Explorer, double-click download iso to mount it.

In my case, iso image is mounted as H:\

 

Step 3

Run cmd as administrator  and type those commands to install language packs. "ja-JP" means Japanese. Change it to your language code. H:\ should be replaced your mounted iso image drive letter.

dism /online /add-capability /capabilityname:Language.Basic~~~ja-JP~0.0.1.0 /source:H:\LanguagesAndOptionalFeatures /LimitAccess

dism /online /add-capability /capabilityname:Language.Handwriting~~~ja-JP~0.0.1.0 /source:H:\LanguagesAndOptionalFeatures /LimitAccess
dism /online /add-capability /capabilityname:Language.OCR~~~ja-JP~0.0.1.0 /source:H:\LanguagesAndOptionalFeatures /LimitAccess
dism /online /add-capability /capabilityname:Language.Speech~~~ja-JP~0.0.1.0 /source:H:\LanguagesAndOptionalFeatures /LimitAccess
dism /online /add-capability /capabilityname:Language.TextToSpeech~~~ja-JP~0.0.1.0 /source:H:\LanguagesAndOptionalFeatures /LimitAccess
dism /online /add-capability /capabilityname:Language.Fonts.Jpan~~~und-JPAN~0.0.1.0 /source:H:\LanguagesAndOptionalFeatures /LimitAccess

 

Step 4

 

Open settings (right click start icon and choose Settings) → Time ＆ Language → Lauguage ＆ region, push "Add a language" button to add language. Some caution message such as your computer is offline may be shown but adding language should work.

Some thoughts

The dism command argument /online does not mean internet connection, it means language pack will be installed onto currently running OS.

Without /LimitAccess option, dism try to connect internet.

It seems /add-package option is deprecated and replaced to /add-capability
