Hi Chong,
Thank you for bringing this up. I'm Adrian, an independent advisor, here to help.
To answer your question. Yes, it's normal to have both x64 and x86 versions installed. Do not uninstall them unless you are 100% sure no app depends on them. Many 64-bit systems still run older 32-bit apps, which require the x86 version.
Here are a few safe and effective steps to uncover hidden disk usage.
Step 1) Go to Settings > System > Storage
Click Show more categories
Select Temporary Files
Safely remove
Delivery Optimization Files
Temporary Internet Files
Recycle Bin
Previous Windows installation (if present)
Then go back and click "Cleanup recommendations" if available.
Step 2) Check System Restore and Hibernation
These can silently consume tens of GB.
Disable or shrink System Restore:
Press Win + R, type sysdm.cpl, go to System Protection tab
Click Configure
Reduce Max Usage to around 5%, or turn it off temporarily
Disable Hibernation (if not needed):
Run this command as Admin in PowerShell
powercfg -h off
This deletes the hiberfil.sys file, which can be several GBs.
Step 3) Apps and games from the Store can leave behind cache
Run this command
wsreset.exe

If none of these free up space or if you find a folder consuming way too much, let me know what it is and I’ll guide you from there.
Best regards,
Adrian
