Does doing this sound like a good idea?

It is possible to make sound work on Safe Mode.
Press Windows + R, type devmgmt.msc, press Enter and look for your sound device. (e.g. Reatlek High Definition Audio) Double-click it.
Go to the tab 'Details' and click the drop-down list. Select 'Driver key' and copy the text from 'Value'
Copy the text into a word processor (e.g. Notepad)
Replace all lower-case letters with capital letters and remove the \0000.
Open Registry Editor (Windows + R > regedit) and locate HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Network.
Create a new key (Rightclick > New > Key)
Copy the text from your word processor and paste it into the key name.
Edit the '(Default)' key and type 'Sound, video and game controllers'.
Create a new key called 'AudioEndpointBuilder', 'MMCSS' and 'Audiosrv'
Edit all their '(Default)' keys and type 'Service'.
Restart your computer
Go to Services (Windows + R > services.msc) and start Multimedia Class Scheduler and Windows Audio Endpoint Builder.
Then start Windows Audio Service

Mainly I want sound to work in Safemode and well I'm wondering if this sounds safe
