Reserved Storage in Windows 10

He meant, instead of doing it manually as shown in my little tutorial

 

How can you edit a registry hive offline without loading a registry hive first?

 

That part is in my tutorial, he referred too

 

That's why I made my initial comment that just "reg add" won't work. I'm confused now.

I'm aware. I am listing this step to skip the use of using the regedit GUI, not anything else.

This reserve thing seems virtually visible to current 1903 OS only

i installed it to VM with vhd, then opened it with 7-zip, no trace of it
mounted the vhd in Windows 8.1, it give the normal actual size

 

I have great news!
- installed 1903 cleanly - resulted in 7GB of Reserve Storage
- edited the registry to get rid of the RS, and it obviously did not work, resulting the previous complaints
- installed kb4497093 a bit earlier normally through WU, OS went to .86
- noticed the free space on the OS SSD partition up to about 45GB from 39-ish, took a look in the Storage settigns... aaaand it's gone. RS is gone.
All it takes is one update with the registry setting applied, and the RS is removed. I wondered why it took a bit longer when it applied the CU.

 

Did you post this before on MDL, i have read this before, i thought, yesterday or the day before yesterday.

 

Deja vu, welcome to telepathy and parapsychology class

 

Must be, it was someone saying, the RS was gone after installing an update too, but can't find it anywhere, so must be deja vu

 

Doing an inplace upgrade will also remove it.

 

@toyo, I've linked to your online solution at the tutorial

 

It's not yet known precisely how it works, one big concern is it might prevent SSDs from making use of that space for lifespan-extending operations.

 

I already had 18362.86 installed so I uninstalled and reinstalled the cumulative update to get rid of reserved storage.

 

Damn, I should've thought of that instead of doing an in-place upgrade because I forgot to edit the key in my install.wim when I clean installed the other day!

So there we have it, an easy way to remove reserved storage on running systems.

 

Good to hear it worked, at least now we know that the registry tweak is a valid choice even for those with the OS already installed. I feel Microsoft should be able to provide a toggle for it, since it's clearly quite easy to get rid of.

 

I don't think the registry tweak completely removes the reserve storage. Try running fsutil command and you'll still see the reserve storage (much smaller than a 7gb space but still there).
