I've had it up to my eyeballs with the nagging Windows low disk space warning and offers from my helpful operating system to clean up the junk I have lying around. If you have a drive or two that remains constantly on the edge of full for good reason, you probably share my sentiment.

I went looking for a solution, and I found a few. Most of them involved lengthy descriptions of how to navigate the registry just to add the "NoLowDiskSpaceChecks" key. Here's a much easier solution; one command line you can cut and paste into any open command prompt window.

REM copy here 
regini HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer "NoLowDiskSpaceChecks" = REG_DWORD 1 
REM end copy here

(REM lines added to make this easier to copy correctly)
