Why Program Files folders, Windows, and Users folders have "shared" status in Windows explorer?
Windows is installed 4 days ago, with only the default "local" admin during install.
No email is used, one drive is not installed.
Any features related to remote access are disabled after install.

Hey
@Parkinsond,
That's an interesting observation—I've seen similar questions pop up before on fresh Windows installs (sounds like Windows 11 based on the dark mode and UI). Don't worry, this doesn't sound like a security issue or anything malicious, especially with your setup being so recent and locked down (local admin only, no OneDrive, no remote features). Let me break it down factually based on how Windows handles folder sharing.
### Quick Explanation of "Shared" Status
- The "Status: Shared" in the Explorer status bar (or details pane) typically indicates that the folder is configured for **network sharing** via SMB (Server Message Block), which is Windows' built-in file sharing protocol.
- However, not all "shared" indicators mean the folder is openly accessible over the network—some are default administrative setups that are hidden or restricted to admins only.
- System folders like these aren't meant for casual sharing, but Windows does set up a few defaults during install for administrative purposes or legacy home networking (e.g., workgroups).
### Why This Happens on a Fresh Install
Here's what's likely going on for each folder you mentioned, based on standard Windows behavior:
- **
Users Folder (C:\Users)**: This one
is shared by default in Windows 10/11. It's set up as a visible share named "Users" (network path: \\YourPCName\Users).
- Purpose: It allows limited network access to subfolders like Public (for sharing files in a home network or workgroup). Permissions are tight—usually read-only for authenticated users, and NTFS security restricts deeper access (e.g., you can't poke into other user profiles without admin rights).
- It's not hidden, so Explorer shows it as "Shared." This is normal and exists even on a clean install with a local account.
- **
Windows Folder (C:\Windows)**: This isn't visibly shared, but it falls under a
hidden administrative share called ADMIN$ (network path: \\YourPCName\ADMIN$).
- Hidden shares (ending in $) don't show the shared icon in Explorer and require admin credentials to access remotely. They're for system admin tasks, like remote management or backups.
- Explorer might still flag it as "Shared" in the status bar because it's part of that underlying share. Again, totally standard.
- **
Program Files (and Program Files (x86))**: These
aren't shared by default—no visible or hidden share is created for them specifically.
- If you're seeing "Status: Shared" here, it could be a quirk in how Explorer displays status for folders under the root drive share (C$, another hidden admin share for the entire C: drive). Sometimes, the status bar "inherits" this from the parent drive, even though Program Files itself isn't independently shared.
- It's not a bug per se, but more of a UI thing—especially if you've disabled remote features, as that might not fully remove the display flag.
Since you disabled remote access features (like Remote Desktop, file sharing services, etc.), these shares should be inactive or inaccessible from outside. Windows still creates them during setup, but they're not "active" unless you enable network discovery or SMB.
### How to Verify and Confirm It's Not Shared
To double-check and put your mind at ease, here's what you can do (no tools needed, just built-in Windows stuff):
1. **Check Folder Properties**:
- Right-click the folder (e.g., Program Files) > Properties > Sharing tab.
- If it says "Not shared" and no network path is listed, it's not actively shared over the network.
- For Users, you'll likely see it listed as shared— that's expected, but check the "Share..." button to see permissions (should be restricted).
2. **View All System Shares**:
- Right-click Start > Computer Management (or search for it).
- Go to System Tools > Shared Folders > Shares.
- You'll see the full list of default shares (like C$, ADMIN$, IPC$, and Users). Hidden ones end in $ and aren't accessible without admin login.
- If something looks off (e.g., extra shares you didn't create), you can right-click and stop sharing them.
3. **Disable Administrative Shares (If You Want)**:
- These are on by default for admin convenience, but if you're paranoid, you can disable them via registry (backup first!):
- Open Regedit > Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters.
- Create a DWORD named "AutoShareWks" (or "AutoShareServer" on Pro editions) and set it to 0.
- Restart your PC. This stops auto-creation of admin shares like C$ and ADMIN$.
- Note: This might break some legit remote tools if you ever need them.
### Is This a Security Risk?
Not really in your setup—especially with remote features disabled and no network exposure. These shares require:
- Network discovery enabled (which you can turn off in Settings > Network & Internet > Advanced network settings).
- Firewall ports open (SMB is port 445, blocked by default if sharing is off).
- Actual credentials to access.
If your PC isn't on a network or exposed to the internet, it's moot. No malware would "activate" this without deeper system compromise, and your fresh install rules that out.
If you share a screenshot of the Sharing tab for Program Files or the Shares list in Computer Management, I can help interpret it further. Or if this started after installing something specific (like Malwarebytes from your screenshot), that might be a clue.
Hope that clears it up—let me know if you have more details!
