Windows 10: How big is 2021-08 Cumulative Update Windows 10 Version 20H2 for 64x KB5005033?

I'm asking this because it's taking forever to download. The number hasn't gone up after 5 minutes.

Cumulative Update for Win10 Version 21H1 (KB5005033) fails in BSOD

Typical Microsoft
2 things that are always guaranteed: adding new bugs and failures.

Cumulative Update for Windows 10 Version 21H1 (KB5005033) Failed to Install resulting on reboot in a BSoD.
The next reboot attempts to system repair which fortunately succeeds (!!!)

Updates in Settings thereafter shows:
Installation Failure: Windows failed to install the following update with error 0x800F0845: 2021-08 Cumulative Update for Windows 10 Version 21H1 for x64-based Systems (KB5005033).

Hello Ghost,
On one computer I ran aground in the first step (see annexed picture). The other one was still awaiting the 20H2 update. I unleashed two of your proposed actions including running the dat. file as administrator. This one crashed after 40% of the update. This is really a pain the neck. I did not want to do the in-place upgrade, fearing this would eventually lead to a full fresh install. Any idea what is wrong with windows 10?
