Can you open a Command Prompt (Admin) or Powershell (Admin) and enter these cmds -

dism /online /cleanup-image /startcomponentcleanup

dism /online /cleanup-image /restorehealth

sfc /scannow

exit

If the sfc /scannow reports no integrity violations, try Windows Repair again to see if it completes.

Glad to see you have found and resolved the problem.

Can you run a cmd prompt as an admin and enter chkdsk /f to see what it reports.

Follow the prompts for a reboot for it to start.

If you can download it, there is a disk that will get you into Windows and it's the Hiren's Boot Disk -

Boot up with it and it will load Windows.

You could also see if the cmd chkdsk /f does anything for you.

At the cmd prompt can you enter chkdsk and let me know what it reports.

This is a read only disk check so should produce its report on screen.

For a repair install, open Windows/File Explorer - double click on Computer - insert the disk and double click on its drive then click on Repair your computer which you will see lower left.

From memory the computer will do the rest to reinstall Win 7 without affecting your installed programs.

Hope this helps.

I think it used to take almost 4hrs on my Win 7.

Please email [email protected] and address your request there.

Let me know how you get on.

It's quite possible that your Win 7 install disk doesn't include SP1.

Download sites for Win 7 seem to be very few these days but I've found this one -

When you have created the disk, boot up with it, select Repair your computer and navigate to the Command Prompt and enter these cmds -

bcdedit |find "osdevice"

For clarity, that is a Pipe symbol before find and is the upper case of \

Then using your partition letter instead of the X I have exampled, enter this cmd -

sfc /scannow /offbootdir=X:\ /offwindir=X:\Windows

When that has completed, enter exit to close the cmd window, remove the disk and reboot.

After the reboot, run another sfc /scannow in normal mode to see what it now reports.

If it still shows corruption then try your 2021 back up.

Sometimes power shutting the machine down by pressing and holding down the power button for about 30secs and then a restart can resolve anomalous problems.

If that doesn't work then open a Command Prompt (Admin) and enter these cmds -

dism /online /cleanup-image /restorehealth

sfc /scannow

Enter exit to close the cmd window and see if it now works.

When you get the there isn't enough free space, it usually refers to the Temp folder being over populated.

Go Start - type %temp% and press enter.

Press CTRL and a together to highlight then CTRL and d together to delete then follow the prompts and try to do what you were trying to do.

Don't forget to empty your recycle bin.

I'm sorry to hear that and don't know why it should have happened.

I suggest you use the program's Registry Backup to restore the registry, but if that doesn't resolve, then go into System Protection and use your restore points.

I've always created a system image prior to test running new versions of the repair program and Shane advises manually creating a restore point before using the program.

Ignore the program's option to create a restore point because while it says it has done so, it doesn't physically create one.

To restore your Windows to how it should be, I would suggest performing a repair install for which you will need install media.

You can create install media after reading - https://support.microsoft.com/en-us/windows/create-an-iso-file-for-windows-10-38547366-1dcb-7afd-1726-9eb222d72705

Once you've created the media (DVD or USB) open Windows/File Explorer - This PC - insert the media and double click on its drive.

This will start the process when using a DVD but will open to its files when using an USB where you would then double click on set up Application.

A repair install doesn't affect installed programs.

I'm not sure about that as you didn't actually run the program.

However, reboot and and try the repair program again.
