Absolutely, those steps should definitely help troubleshoot the issue. Another thing you might want to consider is checking your system for any corrupted files that could be causing the update to fail. You can do this by running the System File Checker tool:
- Open Command Prompt as administrator.
- Type
sfc /scannow
and press Enter.
This will scan your system for corrupt files and attempt to repair them. It might take a cramped while, but it's worth doing to ensure there isn't a deeper issue at play.
And just in case that doesn’t resolve it, sometimes simply uninstalling and then reinstalling the app that won't update (in this case, WhatsApp Desktop) can work wonders. This clears out any unique issues with the app's installation files and allows for a fresh install.
Hope one of these solutions does the trick for you!
