Recently one of our readers faced a problem with Windows 7 Backup and Restore after installing and then uninstalling Acronis True Image. When the user double-clicked the Backup and Restore item in the Control Panel, nothing happened except for a brief hour glass.

Supposedly, the user had enabled the Windows integration feature in Acronis True Image software, which in turn replaced the Windows 7 Backup utility by modifying the Backup and Restore shell folder registry keys. And uninstalling Acronis True Image did not revert back the original shell folder values for Backup and Restore, causing it inoperable. Running the file "C:\Windows\System32\sdclt.exe" manually did not launch the Backup utility either.

Fixing the Backup and Restore Registry Keys

1. Click Start, type Regedit.exe and press ENTER:

2. Go to the following branch:

HKEY_CLASSES_ROOT \ CLSID \ {B98A2BEA-7D42-4558-8BD1-832F41BAC6FD}

3. Right-click on the key and choose Permissions…

(The above registry key and sub keys are owned by TrustedInstaller by default, and you may have to take ownership of the keys in order to restore the default values. ResourceDLL and ResourceID seems to be the two values that Acronis True Image modifies in order to integrate with the shell.)

4. Click Advanced, and select the Owner tab.

5. Look at the Current owner information. If TrustedInstaller is currently the owner of the key, select Administrators from the list below, select Replace owner on subcontainers and objects, and then click OK.

6. Select Administrators, allow Full Control permission and click OK.

7. Run the Windows 7 Backup Restore – Shell Folder Registry Fix. Download Fix-W7BackupKeys.zip, unzip and run the REG file.

You’ve fixed the Windows 7 Backup shell folder key. Next, restore TrustedInstaller back as the owner of the above registry key, and revoke Full Control permission for the Administrators group.

Reinstate TrustedInstaller as the Owner

8. Right-click on the {B98A2BEA-7D42-4558-8BD1-832F41BAC6FD} key and choose Permissions…Click Advanced, and select the Owner tab.

9. Click Advanced, and select the Owner tab.

10. Click Other users or groups… button

11. Type NT Service\TrustedInstaller in the text box, and click OK. This adds TrustedInstaller group to the listing.

12. With TrustedInstaller selected, select Replace owner on subcontainers and objects, and then click OK.

13. Select Administrators, uncheck Full Control and click OK.

Editor’s note: The Windows 7 Backup issue discussed in this article is not to be confused with another similar sounding Windows 7 Backup problem ("Set up backup" or click "Change settings" links within the Backup and Restore applet non-functional, which is a third-party shell extension saga.)

    I am attempting to restore Windows 7 Backup and Restore after having uninstalled Acronis True Image Home 2012. I am able to complete the first 6 steps without a problem, but I do not understand step 7. Where do I get the Windows 7 Backup – Restore Shell Folder Registry Fix? And from where do I download Fix-W7BackupKeys.zip? Does Windows 7 automatically unzip a .zip file?

    Any help would be appreciated.
