Windows 10: Backup of HKEY_CLASSES_ROOT\*\ registry folder required!

Hello everyone,I am fighting to bring my Windows back to life.Everything was completely fine with my Windows, I just tried to fix "Open with" after right click feature as it was not working properly, I found that the only one entry which I need to add is:Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers\Open With] @="{09799AFB-AD67-11d1-ABCD-00C04FC30936}"when I opened regedit.exe I realized that I don't have access to this folder HKEY_CLASSES_ROOT\*\ and also it looks like folder is empty or I can not see because I don't have permissions, please look

:)

 

Is it safe to remove HKEY_CLASSES_ROOT registry?

I wanna know if it is safe to remove the HKEY_CLASSES_ROOT registry. Can It ruin windows or any software?

I saw a tutorial where they mentioned about deleting the HKEY_CLASSES_ROOT, but I don't know if I should trust them.

 

Registry Backup - Question

Registry Backup

I am reading a book, Windows 10 Anniversary Update. It makes these two statements.

• File History also keeps a copy of your Registry.
• Every time you start your computer, it makes a backup copy of that Registry.

Where and how do I find these copies?

Thanks,

Jerry

How to backup and restore registry using only win10 iso command prompt

The only access post windows upgrade is Windows RE using a windows 10 iso.

Registry steps may be needed that require deletion of the registry entries.

Aren't there two methods for backup: a single change and the whole registry?
I've never done either and need specific steps using Windows RE command prompt.
Also I've never restored a registry backup.
How do you restore a single backup using Windows RE command prompt?
And how do you restore the whole backup?

Again I've never done any significant changes in the registry and need specific steps using only the Windows 10 iso.
