    Registry is corrupt after uninstalling Avast


    Windows 8.1 pc with a 120gb SSD primary and 1tb HHD secondary.

    i decided to uninstall Avast as we have a spare licence on a paid anti virus package. The pc was checked to make sure all updates were done and drivers were current with a restart after each. But after uninstalling Avast and restarting I noticed the message Preparing Automatic Repair, which was not successful. After which it attempted to diagnose. I have tried to Refresh but it says There was a problem with refresh. No changes were made. it says there are no System Restore points. Start up repair couldn't repair PC and gave the log file location which I opened via the command prompt. That states Number of root causes = 1. All tests show results completed successfully and error code = 0x0, apart from one, which is

    Name: Registry Hives test
    Result: Completed successfully. Error code = 0x0
    Time taken = 859ms
    Root cause found:
    ---------
    Registry is corrupt
    Repair action: Registry roll back
    Result: Failed. Error code = 0x2
    time taken = 0ms

    Now I don't know what to do! BUT before I do anything I want to consider and would ask for advice on this, the 120 SSD that Windows is on is almost full. I would consider getting a larger capacity especially if that may be a better workaround. So can anyone advise..... Should I try and somehow get the problem resolved with the existing SSD, or shall I get a new SSD and install Windows 8 on that and then try and extract what I may need off the old SSD? I should add I have a Windows 8 installation disk and then updated to Win 8.1 via a download.

    i should additionally add..... I'm not an expert with these things so will need easy to understand help!

    thank you in advance

    Try this, open "System Restore", tick "show more restore points".
    Look for highlighted "SYSTEM" as in attachment shown.
    Click on this to restore registry.

    Right click on bottom left hand corner and open "Command Prompt (Admin) and copy paste the following.
    sfc /scannow

    You might have to do this 2 or 3 times

    Thanks again Dencal..... The options appear limited and right click doesn't work. However, there is an Advanced Troubleshooting option to run the Command Prompt so I selected that. I typed in your command, but it can't perform the task because there is a repair pending which requires a restart - and the restart doesn't work. I've repeated it a few times but I'm stuck in a loop!

    Try this, you can copy and paste the following in the ADMIN Command Prompt.
    dism /online /cleanup-image /restorehealth

    Thanks Dencal
    photo of results below..... I should say that I can't copy and paste as I can't open Windows to use the computer! So I can't be sure I have typed the command correctly - are there any spaces?

    Hi Jane.
    Windows PE is a very limited O/S which has limitations in recovering existing installations or data.
    See link below, unfortunately I cannot help you anymore, perhaps some other member can.
