Windows 10: Trying to stop low disk space warning via regedit: need permission

My system drive has a lot of free space on it. I have a scratch disk which is full of cache for a video editing program. It's always going to be full for as long as I have any videos that I'm editing. I would like Windows to stop telling me that the disk is full; Windows has no business on that drive; there is nothing there but video cache.

My search has led me to this thread with the following instructions: Windows 10 - disable the low disk space warning? - Microsoft Insider Previews - Neowin Forums

I cannot follow the instructions due to a permissions issue. I ran regedit.exe as administrator to gain elevated permissions but the write access for the key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows Search\Gather is granted only to TrustedInstaller and WSearch while SYSTEM has "special permissions". Administrators and Users have Read only permission. The ownership is given as TrustedInstaller.

How can I edit this key? Thanks.

Low Disk Space Warning

Please see:

Low Disk Space Warning

HKLM = HKEY_LOCAL_MACHINE

HKCU = HKEY_CURRENT_USER

To disable - Low Disk Space Warning

NoLowDiskSpaceChecks (DWORD 1)

Before Win10 the registry key is behind HKEY_CURRENT_USER

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

After Win10 the registry key is behind HKEY_LOCAL_MACHINE

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

The procedure is the same as in the 2013 KB article you mentioned (although, Windows 10 changes the active registry entry/key location)--

Glad it helped..

A Wiki has been created to help others..

 

Low Disk Space Warning

For Win10:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

NoLowDiskSpaceChecks DWORD 1

Note for Win10 the key is under HKLM.

After adding/changing the key, reboot..

 

Your are prevented from editing such keys for good reason - to protect you from yourself. Be VERY careful how you use the following guidance. Best to make a restore point before you start, or even a system image.

You need to take ownership, add your user account with full access then edit the key. Then undo the permissions changes, removing yourself and making TrustedInstaller the owner again. Start by clicking the 'Advanced' button in 'Permissions'.

NB: to make TrustedInstaller the owner again you have to be able to find it first. Type its full name:
NT Service\TrustedInstaller and click the 'check names' button.

 

Thanks for the advice. I don't think I have an account on the computer - previously I had an account with my name but this is a new installation on a more or less new computer and I think my account is a Microsoft account which doesn't appear to be stored locally. I tried setting the ownership to administrators, having started Regedit.exe as administrator and while the ownership did transfer I get an error message when trying to change the permission to full:

When I tried to give ownership back, Windows denied the existence of TrustedInstaller! I used system restore to return ownership.





Edit: There's information in the thread I linked which might cover this. I'll try it later. Windows has already stopped giving the low disk space warning for some reason.
