Choose the right removal method first
Registry editing is not the general-purpose profile deletion method. Microsoft’s supported procedure removes a normal profile through the User Profiles dialog, while the registry is useful for investigating a leftover ProfileList entry after an incomplete deletion, a temporary profile, or a failed sign-in. The correct choice depends on what you are trying to accomplish.

| Goal | Best approach | Profile may be loaded? | What happens to files? |
|---|---|---|---|
| Remove a user normally | User Profiles dialog | No; sign out first | Windows removes the profile through the supported workflow; preserve anything needed before deletion |
| Investigate an orphaned or duplicate registry entry | Inspect ProfileList and use Microsoft’s cleanup script in report mode |
No; cleanup is for unloaded profiles | Registry findings and folders must be assessed separately |
| Remove a confirmed orphaned registry reference | Export the key, then delete only the verified SID subkey or use the cleanup script’s deletion switch | No | Removing the mapping does not substitute for preserving or separately removing the user folder |
| Free space from old profiles | Microsoft’s aged-profile PowerShell script | No; the script skips loaded profiles | Profiles meeting the age rule can be deleted after you review the report |
| Recover from a corrupt profile | Create a new administrator account and migrate files | Use the old profile only while signed out of it | Personal files can be copied; email, applications, and Store sign-ins may need separate work |
Microsoft states that these operations require membership in the local Administrators group or delegated authority. Use an administrator account other than the profile you intend to remove.

- Sign out of the target account. Sign in with another administrator account. Do not attempt to delete the profile that is currently running your desktop, and check that no service or scheduled task is keeping it loaded.
- Confirm that the data is no longer needed. Check the user’s Desktop, Documents, Downloads, Pictures, application data, and any organization-specific folders. If the account is needed but only its profile is damaged, use the migration procedure below instead of deleting it.
- Export the registry key. Press
Win+R, enterregedit.exe, and approve the elevation prompt. Browse toHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList. Select the key, choose File → Export, and save the.regfile somewhere you can reach even if Windows later fails to sign in. - Know how to undo the change. Registry Editor can restore the saved file with File → Import. Importing a backup does not replace a restart; reboot after restoring and check the affected sign-in.
A registry export is a safety net, not a substitute for identifying the correct profile. Never choose a SID because its number “looks like” the user’s. Match the path stored in that SID’s values to the actual profile folder.

Use the supported User Profiles dialog for a normal deletion
- Sign out of the profile being removed and sign in with a different administrator account.
- Open Control Panel. Set View by to Large icons, then select System.
- Choose Advanced system settings. In the System Properties window, open the Advanced tab.
- Under User Profiles, select Settings.
- Select the profile by its user-folder path and choose Delete, then confirm.
- Restart Windows and test the remaining accounts. Confirm that the intended profile folder and sign-in behavior are correct before removing any leftover data.
On Windows 10 and Windows 11, Microsoft notes that this documented Control Panel route may open the Settings experience for the profile operation. If the profile is in use, the Delete button can be unavailable or the operation can fail; sign out, close applications and services associated with the account, and try again from the separate administrator account.
Find the correct ProfileList entry
Open the exported-and-backed-up key at HKLMSOFTWAREMicrosoftWindows NTCurrentVersionProfileList. Each subkey normally has a security identifier (SID) such as S-1-5-21-…-1001. Select a SID and read its ProfileImagePath value. The value should identify the exact folder, for example C:UsersAlex. Use that path, not the final digits of the SID, to identify the account.
| Finding | What it can indicate | Safe next step |
|---|---|---|
ProfileImagePath points to the active, intact user folder |
A normal profile mapping | Do not delete it while the profile is loaded. Use the supported User Profiles dialog for normal removal. |
A SID key ends in .bak |
A failed or interrupted profile sign-in, often leaving an alternate registry entry | Treat it as a diagnostic signal. Compare paths and loading state; do not delete solely because the suffix is present. |
| Two SID entries reference the same folder | Duplicate or stale ProfileList information | Verify which entry belongs to the account and whether either profile is loaded before changing anything. |
The folder in ProfileImagePath is missing |
An orphaned registry reference, an intentionally moved folder, or a path problem | Check backups and account ownership. A missing folder alone is not permission to erase the registry entry. |
The folder lacks NTUSER.DAT or NTUSER.MAN |
A profile hive may be incomplete or the entry may be orphaned | Use Microsoft’s cleanup script in report mode and investigate before enabling deletion. |
A temporary (TEMP) profile or an unreferenced user folder is reported |
Windows may have created a temporary sign-in or left a folder without a valid registry mapping | Save any needed files, sign out, and diagnose the corresponding ProfileList entries rather than deleting by folder name alone. |
Microsoft’s ProfileList cleanup script checks for these conditions, including .bak entries, duplicate paths, missing profile folders, missing profile hives, orphaned ProfileGUID values, and unreferenced user folders. Those findings tell you what to investigate; they are not automatic approval to delete.

Remove a confirmed orphaned registry entry manually
Use this procedure only after you have exported the key, confirmed the exact path, and established that the profile is not loaded and is no longer needed.
- In Registry Editor, remain at
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList. - Open each candidate SID subkey and compare
ProfileImagePathwith the folder you investigated. Check whether a paired normal SID and.bakSID exist. - Select only the SID subkey that you have positively identified as stale or orphaned. Right-click it, choose Delete, and confirm. Do not delete the entire
ProfileListkey. - Close Registry Editor and restart Windows. Test sign-in with the affected and unaffected accounts.
Deleting a ProfileList subkey removes the registry mapping; it is not a secure erase of the folder. Keep the folder until you have recovered required files and confirmed that no application or account still depends on it. If the profile is still valid, the supported User Profiles dialog is safer than manually deleting its mapping.
Clean orphaned entries with Microsoft’s diagnostic script
For a machine with several stale entries, Microsoft provides a separate cleanup script for ProfileList information and temporary profiles. It examines the registry path, warns about .bak and duplicate references, detects missing folders and profile hives, and can inspect orphaned ProfileGUID entries and unreferenced user folders.

- Run it first without
-clean. The default behavior reports findings without deleting them. - Review every reported SID, path, folder, and hive. Confirm that the account is not loaded and that required files are backed up.
- Use
-cleanonly for entries you have verified as orphaned. A cleanup switch is an instruction to delete, not a repair for a currently used or corrupted profile. - Restart and verify sign-in behavior and the remaining profile folders.
If the script reports a legitimate profile as missing a file, stop and investigate. A damaged profile may need migration, while an absent folder may reflect a deliberate move or a backup restore rather than an orphan.

Use the aged-profile script for old, unused accounts
Microsoft also documents a Windows 10 and Windows 11 PowerShell script that finds profiles unused for a specified period. It uses registry timestamps, which Microsoft describes as more reliable for this purpose than relying only on the NTFS timestamp of NTUSER.DAT. The script cleans only profiles that are not loaded when it runs.
The documented example targets profiles unused for at least 60 days:

When deletion is the wrong fix: migrate a corrupted profile
A profile that signs in temporarily, rejects a password that works elsewhere, or repeatedly fails to load may be corrupted rather than orphaned. Microsoft’s recovery guidance for Windows 10 and Windows 11 is to create a new administrator account, copy the needed files from C:Users<Old_Username> to the new profile, restart, and sign in as the new user.
- Create a new local administrator account while you can still sign in with an administrator.
- Sign out of the damaged profile and sign in to the new account.
- Copy the old profile’s personal files from
C:Users<Old_Username>into the corresponding folders of the new profile. Do not blindly copy the old registry hive as a way to “repair” it. - Restart and sign in again with the new account.
- Reconfigure applications and verify documents before retiring the old account or cleaning its registry entry.
Email data may require a separate import. Some applications may need reconfiguration or reinstallation, and Microsoft Store apps may require a new sign-in. Deleting the old ProfileList entry before this migration can make recovery harder.
Verify the result and recover from a mistake
- The Delete button is unavailable: confirm that you are using another administrator account and that the target user is signed out. A service or scheduled task can also keep a profile loaded.
- A
.bakentry returns: stop deleting keys by suffix. Compare everyProfileImagePath, check the profile folder and hive, and run the cleanup script in report mode. - Windows signs in with a TEMP profile: save any files created during that session, sign out, and investigate the original profile’s mapping and hive. Do not treat the temporary folder as the user’s permanent data.
- The folder remains after registry cleanup: this is expected when only the registry mapping was removed. Preserve or remove the folder separately after confirming that no data is needed.
- The change caused a sign-in problem: from an administrator account, open
regedit.exe, choose File → Import, select the saved.regbackup, restart, and test again.
The practical rule is simple: use the User Profiles dialog for a normal removal, use ProfileList inspection and scripts for confirmed orphan cleanup, and create a new profile when corruption is the underlying problem. Registry deletion should be the last, evidence-based step—not the first response to a failed sign-in.
