Unable to Delete imageres.dll.mun File
I recently deleted some content and inadvertently reverted my Windows 11 icons back to the Windows 10 ones. I had been using the Windows 11 icons for quite some time, so the change surprised me. After a Windows update, I found myself unable to delete a specific file because it required permission from TrustedInstaller.exe. While I believe I am the owner of TrustedInstaller, I am unsure why this permission issue has arisen. Previously, I could easily delete this file, but now I'm facing obstacles.

Be cautious when modifying permissions on system files or files owned by TrustedInstaller, as improper changes can affect system stability.
Open a Command Prompt as an administrator, run the commands `takeown /f C:\Windows\System32\imageres.dll.mun` and `icacls C:\Windows\System32\imageres.dll.mun /grant your_username:F` to take ownership of the file, then delete it.
