    Hello and welcome,

    Do you have Avast still installed and if so which version ?
    Please follow the instructions below.

    Retrieve Software Hive
    1. Navigate to C:\Windows\System32\Config and locate the SOFTWARE file.
    2. Please copy this file to your desktop.
    Note: If you receive an error that this file is in-use, try Option#2 below.
    3. Right-click on this file on your desktop and select Send To...Compressed (zipped) folder. This will create a file named SOFTWARE.ZIP on your desktop.
    4. Upload the zip file (SOFTWARE.zip) to your favourite file sharing website (it will be too big to upload here). Examples of services to upload to are FileDropper or One Drive or SendSpace.
    5. Note:Send the downloadlink in a private message as the SOFTWARE hive contains sensitive information!


    Option#2 (only if you are unable to follow the previous instructions)


    • Please download the Freeware RegBak from here: Acelogix Software - Download products
      You will find it at the bottom of the page that the link brings you to.
    • Go ahead and install this program and accept all the defaults. After the last install screen the program should open.
    • Click the New Backup button. Accept the defaults and simply click Start.
    • When it says Finished successfully, click the Close button.
    • This will bring you back to the main screen of the program. You will see one entry in this list with the date that you did it. Right-click on this line-item and select Explore Backup...
    • This will bring you into the folder where the backup was made. You should see a Users folder and a Windows folder along with a couple other files. Double-click on the Windows folder to open it. Then open the System32 folder and then config folder. You should see around 6 files in here, one of which is named SOFTWARE.
    • Copy the SOFTWARE file to your Desktop. If the SOFTWARE file does not exist, please fetch it instead from C:\Windows\System32\config\SOFTWARE.
    • Now right-click on the SOFTWARE file that is on your desktop and select Send to > Compressed (zipped) folder.
    • Then please upload the zip file (SOFTWARE.zip) to your favourite file sharing website (it will be too big to upload here). Examples of services to upload to are FileDropper or One Drive or SendSpace.
    • Note:Send the downloadlink in a private message as the SOFTWARE hive contains sensitive information!
    • You can close any open windows you have as well as the RegBak program now.

    Please follow the instructions below.

    SOFTWARE Hive Replacement with RegBak
    [B]Warning:[/B ]This fix is specific to the user in this thread. No one else should follow these instructions as it may cause more harm than good.


    1. Close all open programs and save all your work. You will need to reboot the machine during this process.
    2. Download the SOFTWARE.ZIP from the private message I sent you.
    3. Right-click on SOFTWARE.ZIP and select Extract All.... Ensure the "Show extracted files when complete" checkbox is checked and click the Extract button.
    4. The software hive will be extracted. You will see the file named SOFTWARE (no extension)
    5. Copy the SOFTWARE hive to where you previously saved a backup. It should be (C:\Windows\RegBak\PC-NAME\DATE\Windows\System32\Config)
    6. Overwrite the one that is currently there when prompted.
    7. Open RegBak by click Start and selecting Registry Backup and Restore. Highlight the backup in the list (it should be the one date today), and press Restore. Click Start. RegBak will reboot your computer to complete the restore process.


    Let me know if the hive was replaced or if there were any errors.

    Restart the machine and try again.
    If it fails again, take a screenshot. Read this on how to take a screenshot.
    Upload the image file to a file-sharing site such as Filedropper or SendSpace and post the download link.

    Are you having the WU issues on the physical computer or on the VM on that machine ?
