Windows 10 Folder Keeps Reverting to Read Only: Understanding the Tick Box That Never Clears

You right-click a folder, choose Properties, untick Read-only, and select Apply. Reopen the window and the box is filled in again. When a Windows 10 folder keeps reverting to read only, it looks as though Windows YYPAUS Login is ignoring you.

In many cases nothing is actually wrong. For folders, the Read-only box is a three-state control. A filled square simply means the attribute applies to the files inside, and Windows shows it that way on almost every folder.

The real question is whether you can change files in the folder. If you can, the box can be ignored. If you cannot, the cause is usually permissions, ransomware protection, or another program locking the folder.

A simple test tells you which situation you are in.

Likely Reasons Behind the Problem

The folder appears or behaves as read-only for these reasons:

• The Read-only box is showing its normal folder state and needs no action.
• Folder permissions do not give your account write access.
• Controlled folder access in Windows Security is blocking a program.
• OneDrive, backup software, or antivirus is locking files in the folder.

Folders copied from an old PC or external drive often carry permissions from a different user account.

Simple Troubleshooting to Begin With

Test whether the folder really is read-only.

1. Open the folder, right-click an empty area, and choose New > Text Document.
2. Rename the new file, type something into it, and save it.
3. If both work, the folder is writable, and the tick box is just showing its normal state.
4. If you cannot save, note the exact error message.
5. Restart the PC and try again, in case a program was holding files open.

A message mentioning “protected” or “unauthorized changes blocked” points straight to Controlled folder access.

Next-Level Steps

Fix the real blocker.

1. Open Windows Security > Virus & threat protection > Ransomware protection and either allow the program through Controlled folder access or check Protection history.
2. Right-click the folder, choose Properties > Security, and make sure your account has Modify or Full control.
3. If you are not the owner, select Advanced, change the owner to your account, and tick “Replace owner on subcontainers and objects.”
4. To clear the attribute from files, open Command Prompt and run attrib -r “C:\path\to\folder\*.*” /s, using your folder’s path.
5. Pause OneDrive or backup software temporarily and test again.

If changes keep reverting even after these steps, run a full malware scan, since some malware locks files deliberately.

A Word of Caution

Change ownership and permissions only for your own data folders, never for Windows or Program Files. Check the folder path carefully before running attrib with /s, because it applies to every file below that folder.

Wrapping Up

A Read-only box that refills itself is usually normal Windows behaviour. Test by creating a file. If you truly cannot save, check Controlled folder access, permissions, and sync software, and the folder will be writable again.
