subject: Windows 7 RC first Bug [print this page] Windows 7 RC version released, Microsoft discovered a major flaw which, through Windows Update, Microsoft Thursday issued a repair patch, the patch has been described as "important" level. According to Microsoft's technical documentation, the impact of the Bug in English 32-bit Windows 7 RC where other languages and all 64-bit version will not be affected. To put it simply, the problem is due to Windows Installer error to set up the system drive root directory of the Access Control List (ACLs).
In the English version of Windows 7 Release Candidate (build 7100) 32-bit Ultimate, the folder that is created as the root folder of the system drive (%SystemDrive%) is missing entries in its security descriptor. One effect of this problem is that standard users such as non-administrators cannot perform all operations to subfolders that are created directly under the root. Therefore, applications that reference folders under the root may not install successfully or may not uninstall successfully. Additionally, operations or applications that reference these folders may fail.
For example, if a folder is created under the root of the system drive from an elevated command prompt, this folder will not correctly inherit permissions from the root of the drive. Therefore, some specific operations, such as deleting the folder, will fail when they are performed from a non-elevated command prompt. Additionally, the following error message appears when the operation fails: Access is denied.
Access is denied.
Furthermore, the missing security descriptor entries protect non-admin file operations directly under the root.
