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 blogI 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_MACHINESoftwareMicrosoftWindows SearchGather 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.Login as "Administrator" LowDiskMinimumMBytes DWORD 0 --> HKEY_LOCAL_MACHINESoftwareMicrosoftWindows SearchGather
Then
HKEY_LOCAL_MACHINESoftwareMicrosoftWindows SearchGathering Manager
take ownership of "Gathering Manager" and assign the ACL rights for the local administrator account (NOT a user account). Modify "BackOffLowDiskThresholdMB" set to 0x00 (0)
(Recommended)
Restore ownership and ACL to the way they were. Not required,.
Ensure that your NoLowDiskSpaceChecks value is DWORD and not string or another type: HKCUSoftwareMicrosoftWindowsCurrentVersionPoliciesExplorerNoLowDiskSpaceChecks = DWORD 0x01
How can I edit this key? Thanks.
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.I cannot follow the instructions due to a permissions issue.

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 ServiceTrustedInstaller 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:Your are prevented from editing such keys for good reason - to protect you from yourself.

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.
