Cannot uninstall Windows SteadyState 2.5 from Windows Vista SP2 RRS feed

  • Question

  • Hello, I am using Vista Home premium OEM, and installed Windows SteadyState v 2.5 sometime back, and now want to uninstall it. Whenever I try to use the Control panel Add/Remove programs panel to SteadyState, the uninstallation process halts with the message "Windows SteadyState cannot be successfully uninstalled when Windows Disk Protection is enabled. Please disable Windows Disk Protection and then try again." I have already disabled Disk Protection from the SteadyState GUI ("Protect the hard disk" is OFF), and tried to initialize the uninstaller in safe mode, but Windows does not load the Installer service in safe mode, nor can I start it from the services.msc panel. Is there any way I can proceed with the said uninstallation ? Please help !!

  • Hi Akash_3110, since the issue is related to WDP, we can remove the WDP cache file manually from registry and drive C.


    1. Restart your computer and start pressing the F8 key on your keyboard. On a computer that is configured for booting to multiple Operating Systems, you can press the F8 key when you see the boot menu.

    2. When the Windows Advanced Options menu appears, select Safe Mode, and then press Enter.

    3. Log onto Windows by using the Administrator account or any user account with the Administrator privileges.

    4. Delete the Cache.wdp file under drive C.


    If the cache file cannot be found, let’s show hidden files with the following steps.


    1. Open drive C: Click Organize menu-> Folders and search option.

    2. Click the View tab. Under Hidden files and folders, click "Show hidden files and folders."

    3. To display other hidden files, clear the "Hide protected operating system files (Recommended)" check box.

    4. Click the "Hide extensions for known file types".

    5. Click OK.


    After that, delete related registry keys and files


    1. Click Start and then Run.

    2. Type in regedit and then click OK.

    3.  Navigate and delete the following two branches:


    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Computer Toolkit

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Windows SteadyState


    4. Search and delete all Windows SteadyState related entries.

    5. Delete files under C:\Program Files\Windows SteadyState


    Hope this helps!
