Turning Off Low Disk Space Warnings in Windows Vista / 7

Windows Vista LogoI’ve already run into one major annoyance in Windows 7, and that is the constant nagging about having low disk space on my WINDOWSSWAP partition. No freakin’ duh, Microsoft. This has been a problem since XP, but Microsoft changed things a bit in Windows Vista, and presumably things remain the same in Windows 7.

No, there is no GUI to tweak the low disk space warnings. You have to use the registry. No, you can’t manipulate the amount of space. I’ve tried setting it to 5MB and Windows 7 is still bugging me about the paltry 5.18MB left on my WINDOWSSWAP. No, there is no way to tweak individual drives. It’s all-or-nothing.

  • Open up an Administrator Command Prompt by holding [Shift] + [Ctrl] while you either double-click a shortcut to cmd.exe, or run cmd.exe from the search/run box.
  • Type regedit and press [Enter]. Yes, we could have regedit from a shortcut or from the search/run box, but we need Administrator privileges to do what the next step.
  • Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Search\Gathering Manager. Right-click on the key and select Permissions. Press the Advanced button, and then click the Owner tab. Select your Administrator account and then click OK.
  • Create a reg file with the following contents, and save it anywhere:Windows Registry Editor Version 5.00


    [HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows Search\\Gathering Manager]

    [HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows Search\\Gather]

  • Import the reg file. You can do this by:
    • Using the command prompt, typing in the full path to the file name (ex: C:\Users\you\Desktop\disable-lowdisk.reg)
    • Using the Registry Editor’s File > Import and using the horrible Vista/7 open file dialog box.
  • Download Sushi’s DriveInfo Gadget Fixed By Switch. Now you can keep tabs on free disk space yourself.
