Hidden Program Files(x86) on Windows 10 Pro 64bit. Why?

Hi all!

I installed a windows 10 pro x64 (1703) "clean install", and the next day i saw the Program Files(x86) is gone, hidden. Why? UAC is disabled, no microsoft account, i am offline account, i am logged in administrator.
I installed few app,( Advanced System Care 10, Avast, Auslogics registry cleaner, etc.) hope it help. Why does Windows 10 X64 hiding in the Program Files (x86) folder?
Thanks. Sorry for bad english.

"C:\Program Files (x86)" is not hidden by default - something after must have changed it.
The only reason you'd not see "C:\Program Files (x86)" is if you installed 32 bit version which you did not. 32 bit Windows only has the "C:\Program Files" directory.

If you have only just done your clean install I'd recommend doing another clean install and not installing Advanced system care 10 or any registry cleaner as it will be easier (and safer) than trying to fix permissions manually.

I understand, so any software installed can cause trouble? After installing Windows, there was the program Files (x86) folder, after installing the other software, and the next day I noticed that the program files (x86) folder was hidden.
Do not install the Iobit software and other registry and pc optimizer software after the next windows installation and then the program files (x86) folder will not be hidden?
Thank you!

I know this is gonna sound ridiculous, but are you sure it's x64?

Program Files(x86) only shows up in x64, not x86 (32 bit). In 32 bit it's Program Files - no Program Files(x86).

Yes, it's x64.

That is what I'd do, yes.

You do not need this kind of software - it makes problems for no benefit.
