Many legacy applications write data (such as configuration information) to areas that are ordinarily inaccessible to standard accounts. This behavior presented few problems in Windows XP, because most users ran with administrative privileges. In Windows Vista, that is no longer the case. To avoid errors that would otherwise arise because users, even those with administrative accounts, are now expected to carry out most operations in a nonadministrative security context, Windows Vista redirects writes (and subsequent reads) to per-user virtualized locations. So, for example, if an application, running in your security context, attempts to write to a location within %ProgramFiles%, the write will be redirected to a comparable location within %LocalAppData%\VirtualStore. When the application subsequently reads what it has written, the read request is redirected to the same virtualized location. As far as the application is concerned, everything is perfectly normal, and the operating system has prevented standard-user access to the %ProgramFiles% folder. If you open a %ProgramFiles% folder in which a virtualized write has occurred, a Compatibility Files button will appear on the Command bar:

But when the program itself needs to read or update its configuration settings, Windows Vista will transparently redirect it to the VirtualStore location. A similar form of virtualization protects sensitive areas of the registry. Programmatic access to HKLM\Software is redirected to HKLM\Software\Classes\VirtualStore. Note the following about virtualization:

Virtualization does not affect administrative access to files or registry keys. Virtualization does not affect 64-bit processes. Virtualized data does not move with roaming profiles. Virtualization is provided for the sake of compatibility with current legacy programs; Microsoft does not promise to include it with future versions of Windows.
Relocating Personal Data Folders
Although the organizational scheme that Windows Vista has adopted for your personal data folders the eleven visible subfolders of %UserProfile% (see Figure 7-13 earlier in this chapter) is much more rational than its predecessor in Windows XP, some users will want to relocate some or all of these folders. If your system volume doesn t have enough space for your video collection, for example, you might want to move the Videos folder to a disk or partition that has more room. But even if space is plentiful on the system disk, a good argument can be made for putting all personal data folders on a volume other than %SystemDrive%. The gist of the argument is:
Separating the operating system and program files from personal data makes it far easier to restore health in the event that your system files become corrupted or damaged by malware. Separating system and program files from personal data encourages the use of disk-imaging backup programs, such as the Complete PC Backup program included with Windows Vista. With personal files located on a separate volume, image backups of system drives are smaller and take less time to create.

Separating system and program files from personal data makes it easier to upgrade to a new version of the operating system (or a different operating system).

For a cogent elaboration of these by ZDNet blogger George Ou, see http://www.vistaio.com/0701. You can easily relocate any or all of your personal data folders as follows: 1. Click your account name at the top of the Start menu s right column to open the root folder of your profile (%UserProfile%), right-click a folder that you want to relocate, and choose Properties from the shortcut menu. 2. On the Location tab of the properties dialog box, enter the address that you want to relocate to. For example, to move this Documents folder from F:\Users\Jean\ Documents to J:\Users\Jean\Documents, you could simply replace the F with a J at the beginning of the path:
3. Click OK. Windows will ask permission to create the target folder if it doesn t already exist. Click Yes. A Move Folder dialog box similar to this one will appear:
