A Windows 11 user experienced an unusual software glitch that caused their account to disappear from the login screen, although the local account remained intact. The original profile and files were still accessible. Two registry modifications were suggested to restore the account's visibility:
1. Navigate to HKEYLOCALMACHINESOFTWAREMicrosoftWindows NTCurrentVersionWinlogonSpecialAccountsUserList, locate the DWORD for the affected account, and change its value from “0” to “1”.
2. Go to HKEYLOCALMACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystem and change the HideFastUserSwitching key from “1” to “0”.
These changes should allow the account to reappear under the login screen's "Other user" section without needing a system restart. Users may need administrative privileges to access the Registry Editor, and a workaround is available for those whose accounts are missing.
