1. Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
2. When you are prompted for an administrator password or for a confirmation, type the password or click Continue.
3. Type the following command, and then press ENTER:
icacls %SystemDrive%\Windows\Temp /grant Users:(CI)(S,WD,AD,X)
Note This command enables every user to create files and directories in the temporary directory.
4. Type the following command, and then press ENTER:
icacls %SystemDrive%\Windows\Temp /grant "CREATOR OWNER":(OI)(CI)(IO)(F)
Note The user who creates a file or a directory in the temporary directory is the CREATOR OWNER. The CREATOR OWNER access control entry grants a user complete control over the file or over the directory. Other users cannot access these files and directories because they are not the CREATOR OWNER.
