Windows 10: Disk Cleanup not freeing disk space

I'm running Windows 10 on a Bootcamp'd MacBook Pro with 256G of SSD of which about 135G is allocated to the Windows partition (according to Properties in Explorer). It is running low on available space (4.06GB available) and Windows updates cannot be installed. Tried Disk Cleanup as Administrator and it shows 6.93GB in Windows Update Cleanup but it doesn't free up that space.
WinDirStat shows C: drive size as 153.8GB of which 99.6GB is used by Windows. Is that normal?
The disk is already compressed. What can I do to clean up the disk space used by Windows Update?
Thank you.

Disk space.

Could be the Windows Update Stores files, .old files, shadow copies, etc.

Try running Windows disk clean up with the "Clean up System Files" option.

Hi joysoder, to properly and safely delete any files not required by your system, run Disk Cleanup twice as explained below. Each time select everything in the list and delete them. Disk Cleanup will not suggest deleting anything that is not safe to delete
. . .

Open File Explorer

Click on your hard drive

On the Manage Tab, click Cleanup

Let Disk Cleanup do its initial scan

Select Everything in the list and choose Delete

Start Disk Cleanup again

Let Disk Cleanup do its initial scan

This time in the resulting dialog, click 'Cleanup System Files'

Let Disk Cleanup run another scan

Select Everything in the list and choose Delete
