Windows popups a balloon tip with a “Low Disk Space – You are running out of Disk Space” warning everytime a hard drive goes below 200 megabytes of disk space. This can get pretty annoying if you have a lot of data on the drive and your disk spaces goes regulary below 200 megabytes on it. There is however a very easy way to turn this message off, it involves a registry setting.
Go to the key HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer \
Right click an empty space in the right area and select to create a new dword value. Name the value NoLowDiskSpaceChecks and double click it. Enter 1 as its value. Close the registry and restart windows so that this new setting will become active. This will turn of the message on all drives.
There is a second way to disable the balloon tip part of this message. It involves disabling all balloon tips which can be done in HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Advanced
Create a new Dword value named NoTrayItemsDisplay and give it the value 1.
The low disk space icon will still appear in your system tray but the balloon tip will not show up anymore.
