How to Merge All User Accounts on Windows Into One Account

AvatarByEric Dawson Computers & Software

Windows does not let you merge all user accounts into one profile; no version of Windows, from Windows 10 through Windows 11, includes a built-in merge function. The workaround that actually works is a manual migrate-then-delete process: sign in as an administrator, copy the files you want from each old account’s Documents, Pictures, Music, Desktop, and Downloads folders into the account you plan to keep, reinstall any programs that were tied to the accounts you are removing, then delete the accounts you no longer need. This keeps your files and folders intact, but it does not merge installed apps, saved passwords, or most personalized settings automatically. The rest of this guide walks through each step, what Windows deletes along the way, and how to avoid wasting gigabytes of storage on an old account’s leftovers.

Why Windows Has No Built-In Way to Merge Accounts

Each account in Windows lives in its own isolated profile, and Microsoft has never shipped a tool, menu option, or command that merges two of them into one. Every account gets a separate folder under C:\Users\[Username], a separate registry hive, and its own entry in the registry path HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList. Nothing crosses that boundary automatically.

A Microsoft Q&A thread titled “I have 2 Windows 11 accounts on my desktop is there a way to combine the accounts into one?” confirms this directly, and Microsoft’s own responders describe the same manual process covered here because no automated merge exists. Another Microsoft Q&A thread, “How do I merge two Users into one?”, gives the same answer and walks through copying files by hand. Independent guides from Make Tech Easier and NinjaOne agree, and none of the sources describe a shortcut that avoids manual copying.

How to Prepare Before Migrating Files Between Accounts

Prepare by signing in with an administrator account, signing out of the account you are consolidating, and backing up its files before you touch anything. Windows requires administrator rights to open and copy files between two user profiles, so a standard account will not get you into the second profile’s folders. The account you are moving files out of also needs to be fully signed out, since an active profile can lock files mid-copy.

What You Need Before You Start

You need three things: administrator access, a signed-out source account, and a backup of that account’s data. Back up first, because the migration steps that follow involve deleting the source account once its files are safely copied, and a mistake at that stage is not easy to reverse. An external drive or a cloud folder both work for the backup; the goal is simply a copy that exists outside the account you are about to delete.

How to Copy Files from One Account to Another

Copy files by opening two File Explorer windows side by side, one showing C:\Users\[Old Account] and the other showing C:\Users\[New Account], then dragging each folder you want across. Focus on Documents, Pictures, Music, Desktop, and Downloads, since those hold the files people actually miss. AppData does not need to be copied; it mostly holds temporary application cache and settings rather than anything you would notice losing.

Which Folders to Copy

The folders worth copying are the ones a person fills in directly: Documents, Pictures, Music, Desktop, and Downloads. Skip AppData unless a specific program you rely on stores its data there and you already know which subfolder to grab. Skipping AppData also keeps the copy fast, since that folder is often the largest one in a profile.

What to Do if You Get a Permission Prompt

Confirm the prompt if you trust the copy, since Windows shows a “Continue” permission dialog when an administrator account reaches into another account’s folders. This is normal behavior, not a sign that something is wrong, and it appears because each profile folder is protected from other accounts by default. Administrator privileges are what let you click past it; a standard account would be blocked outright.

What Happens to Store Apps and Programs After Migration

Programs downloaded from the Microsoft Store stay licensed to the account that installed them, so they do not carry over when you copy files to a different account. Anything installed system-wide in Program Files, on the other hand, stays available to every account on the PC without needing a reinstall. The difference comes down to where an app registers itself, not how you move files.

Reinstall Store apps directly on the destination account if you want to keep using them there. Some programs also offer a system-wide install option during setup, which avoids this problem for future software even if it does not fix apps already tied to the old account. Games and subscription apps tied to a Microsoft Store license are the ones that most often need this extra step.

How to Transfer Settings Between Windows Accounts

Windows settings do not move between accounts on their own, and the built-in options only cover part of the job. The System Properties User Profiles tool can copy from the Default Profile to another profile, but Microsoft designed it for setting up a new account’s starting point, not for merging two accounts that already have their own customizations. A Microsoft Account can sync some preferences, such as theme, across devices, but that sync does not touch files or installed programs.

Using the Built-In User Profiles Tool

Open the built-in tool through Control Panel, System, Advanced System Settings, then the Settings button under User Profiles. From there you can copy the Default Profile to a different account, which is useful when setting up a fresh account with your preferred baseline. It is not built to combine two already-active profiles, so treat it as a starting point rather than a migration tool.

Using Third-Party Tools Like Transwiz

Transwiz backs up an entire source profile as a password-protected ZIP file and merges it into a destination account, which covers more ground than the built-in tool. Make Tech Easier lists it among the practical options for a fuller settings transfer, alongside the manual file copy and the public folder method. It still will not move Microsoft Store app licenses, since those stay tied to the account that purchased them regardless of which tool copies the rest.

How to Delete the Old Account After Migration

Delete the old account only after its files are safely copied and confirmed, since removing an account removes its entire profile folder along with everything still inside it. Windows offers three menu paths to the same result: Settings, the netplwiz command, and Advanced System Settings. Administrator rights are required for all three.

Removing an Account from Settings

Go to Settings, then Accounts, then Other users, select the account, and click Remove. Windows will ask whether to keep the account’s files; choosing “Keep Files” places everything from that profile into a folder on the desktop named after the deleted user. Choosing to delete everything removes the profile folder outright, with no separate copy left behind.

Removing an Account with a Command

Press Windows key plus R, type netplwiz, and press Enter to open the User Accounts dialog, where the same account can be selected and removed. This route reaches the identical account list as the Settings app, just through an older control panel style window. Either path works equally well, so pick whichever one you find faster to reach.

Removing an Account from Advanced System Settings

Open Settings, System, Advanced System Settings, then User Profiles, then Settings to reach a list of every profile stored on the PC, including ones not visible elsewhere. Select the account and delete it from that list to remove the profile completely. NinjaOne’s guide recommends this path when a profile shows up as orphaned or corrupted and does not appear normally in the Accounts list.

What Windows Deletes and What It Keeps

Deleting an account removes its entire profile folder, every AppData folder tied to it, and its registry entries under ProfileList, but everything outside that account is left alone. The user profile folder at C:\Users\[Username] disappears along with all subfolders and files stored there, and the Local, LocalLow, and Roaming AppData folders go with it. Registry entries specific to that account are removed as well, taking account-specific application settings and preferences with them.

Files in C:\Users\Public, anything stored on other drives or network locations, and programs installed system-wide in Program Files are not touched by the deletion. Data belonging to other accounts on the same PC stays exactly as it was. A Microsoft Account tied to the deleted profile also survives; Microsoft Support’s account removal page notes that only the sign-in information on that specific device is removed, and the account itself remains usable elsewhere, including on other PCs and for services like Outlook or Xbox.

How to Clean up Leftover Files After Deleting an Account

Clean up leftover storage by checking whether “Keep Files” was selected during removal, since that option leaves a full copy of the old profile sitting in a folder on the desktop, and by separately checking the profile folder itself for anything Windows did not fully clear. AppData in particular is not guaranteed to disappear the moment an account is removed.

Why AppData Often Lingers After Deletion

AppData often survives because the profile folder is not always cleared immediately, even after the account itself is gone from Settings. A Microsoft Q&A thread on this exact question, “Is it okay to remove AppData folder from Users folder (after removing the user account)”, confirms that the folder is safe to delete once the account is gone, but that Windows does not delete it automatically. Left behind, that single folder can waste 10 to 25 gigabytes (GB) of drive space per abandoned account.

How to Safely Remove Leftover AppData Files

Rename the leftover AppData folder first instead of deleting it outright, then wait about a week to confirm nothing on the PC misbehaves. If everything still works normally after that period, delete the renamed folder for good. This two-step approach catches the rare case where a still-installed program was quietly reading from that folder, something a straight deletion would not give you a chance to notice.

A Worked Example: Adding up the Leftover Space

Add the typical ranges together and a single abandoned profile can hold onto a surprising amount of disk space. AppData alone commonly runs 5 to 25 GB, temporary files add another 1 to 5 GB, and cached Microsoft Store downloads tied to that account can run 2 to 10 GB more. On a PC with two or three old accounts that were never cleaned up, that adds up to 16 to 80 GB of drive space doing nothing, which on a smaller solid state drive (SSD) is often the difference between a PC that feels sluggish and one that runs normally.

Comparing Ways to Move Data Between Windows Accounts

The table below lines up every method by what it actually transfers, since files, settings, and programs each move differently depending on which route you choose.

Method Files Settings Programs Effort Cost
Manual file copy Yes, selected folders No No High Free
Public folder share Yes, via shared location No No Low Free
Transwiz (third-party) Yes Yes No Low Paid
Microsoft Account sync No Yes, partial No None Free
Complete profile copy plus delete Yes, manual selection Some, partial No High Free

A second comparison, this time of what an incomplete deletion leaves behind, shows why the cleanup step in the previous section matters.

Item Typical Size Retained after Deletion Safe to Delete
AppData folder 5-25 GB Yes, unless “Keep Files” chosen Yes, after a week of confirmation
User profile folder Varies Yes, unless “Keep Files” chosen Yes, after backup
Temporary files 1-5 GB Yes Yes
Downloaded program cache 2-10 GB No, if app reinstalled system-wide Yes, if app reinstalled system-wide

I would choose manual file copying for most people because it makes the tradeoff clear. It preserves the folders that usually matter while avoiding a full profile transfer that can bring along temporary files and old application clutter. The extra effort is worthwhile when the alternative is assuming that settings or apps will follow the files. For someone who mainly wants one clean account, keeping the destination profile fresh and reinstalling only the programs still needed is the safer call.

Frequently Asked Questions

Can I Merge Two Microsoft Accounts into One Windows Account?

No, not through Windows account tools; the underlying Microsoft Accounts stay separate no matter what you do locally. You can still consolidate the local presence of both by copying files from the account you are removing into the one you keep, then removing the extra sign-in from that PC afterward. The Microsoft Account itself keeps working normally for email, Xbox, or other services tied to it.

Will Deleting an Account Remove Files Saved in OneDrive?

OneDrive files stay safe, because they live in Microsoft’s cloud storage tied to that Microsoft Account rather than in the local profile folder that gets deleted. As long as OneDrive finished syncing before the account is removed, those files remain accessible by signing into the same Microsoft Account elsewhere. Local files that were never synced, on the other hand, do disappear with the profile unless “Keep Files” was selected.

Can I Undo an Account Deletion if I Forgot to Keep Files?

Not reliably. None of the sources for this guide describe a built-in Windows recovery option for a deleted profile, so the safest approach is backing up before deletion rather than hoping to recover afterward. A file recovery tool might pull back some data from the deleted folder if the drive has not been written to much since, but that is not guaranteed to work.

Does This Process Work the Same on Windows 10 and Windows 11?

Largely yes, though menu names differ slightly between the two. The sources behind this guide focus on Windows 10 and Windows 11, and the Settings, netplwiz, and Advanced System Settings paths all exist on both, even if a few screens are laid out differently. Older versions such as Windows 7 or 8 were not covered by any of the sources checked for this guide.

What Happens to Browser Bookmarks and Saved Passwords During Migration?

They do not transfer through the file copy process described here, since browsers store that data in their own profile folders and sync systems rather than in Documents or Desktop. Signing into the same browser account, such as a Google or Microsoft account, on the destination account’s copy of the browser is the practical way to bring bookmarks and saved passwords along. None of the sources for this guide covered browser-specific transfer steps in detail, so treat that as a separate task from the account merge itself.

Merging Windows accounts always comes down to the same manual routine: copy what you need, reinstall what does not carry over, then delete the account you no longer use and clear out whatever it leaves behind. Skipping the cleanup step is the most common mistake, since an abandoned AppData folder can sit there for months eating tens of gigabytes without anyone noticing. Treat the backup as mandatory, not optional, and the whole process stays low risk from start to finish.

What This Page Does Not Publish

  • I do not cover browser profiles, saved passwords, bookmarks, or email client migration here.
  • I keep this guide to Windows 10 and Windows 11, not older Windows versions.
  • I do not cover linked work accounts or account recovery after an accidental deletion.
