Multiple language setting issues

Windows 11 language / display-language problem on Lenovo ThinkPad E14 Gen 7

I have a new Lenovo ThinkPad E14 Gen 7 running Windows 11 Pro. I am having two related but distinct problems with the Windows language configuration.

1. Windows language / display-language problem

I want Ukrainian to be the Windows display language, while also having English installed as an additional language. However, Windows does not consistently retain the language configuration.

In particular, after reopening the laptop, the Windows interface can unexpectedly switch to Ukrainian instead of retaining the language that was being used previously. The behaviour is strange because my old ASUS laptop has essentially the same language configuration and correctly retains the previously used language.

Troubleshooting already attempted:

• Checked and adjusted the Windows language settings several times.
• Checked the installed languages, language packs and preferred-language order.
• Tried changing the configuration through PowerShell.
• Tried removing Ukrainian through PowerShell, but this did not work.
• Ukrainian could be removed successfully through Windows Settings.
• Tried various PowerShell commands to correct the Windows language/display-language configuration.
• Restarted the laptop several times after making changes.
• The Windows interface has at times appeared partly in English and partly in Ukrainian, even when the language settings appeared correct.
• Ran/tried Windows system-repair procedures such as DISM and SFC. DISM had previously appeared to stall at around 64.01%.
• I also checked the language selector itself; it can show the expected languages even when the actual Windows display language behaves incorrectly.

Today I tried a more complete reset of the language configuration:

• First I deleted Ukrainian.
• Reinstalled it, nothing changed.
• Then I deleted English as well and reinstalled it
• Nothing helped again

1. Lock-screen / reopening problem

There is a separate problem concerning what happens after locking the computer or closing and reopening the laptop.

After reopening the laptop, Windows does not reliably return to the language state that was last being used. Instead, it can switch back to Ukrainian.

I investigated whether this could be related to the language used by the lock screen/sign-in environment rather than the normal user profile.

I have already:

• Checked the normal Windows language settings.
• Checked the preferred-language order.
• Investigated the distinction between the user's language configuration and the lock-screen/sign-in language.
• Tried changing the relevant settings through Windows Settings.
• Tried PowerShell commands intended to align the user, system and sign-in language configurations.
• Restarted Windows after making changes.
• Tried to sign out of my Windows profile, but the attempted sign-out did not produce a normal sign-out; Windows essentially returned to the locked state.

The important comparison is that my old ASUS laptop behaves correctly with the same general language setup: it returns to the previously used language after reopening. The new ThinkPad does not.

At this point, I am trying to determine whether the problem is caused by a corrupted/inconsistent Windows language configuration, by the separation between the user language and the lock-screen/sign-in language, or by a Windows 11/ThinkPad-specific issue.

Thank you!
