You might have noticed that whenever you run short of disk space on some particular drive on your system then Windows shows you a notification message. This is no doubt a very useful feature but on the other hand it also becomes annoying as it keeps disturbing you again and again. Below we have covered a simple way to disable such alerts via the Windows Registry.
Open the Registry Editor by clicking Start, then type regedit and hit Enter. Once it is launched simply navigate to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer from the left sidebar.
Now right click the Explorer and choose New > DWORD (32bit) Value and name this as NoLowDiskSpaceChecks.
Now Double click it and set its value to 1.
Click OK and that’s it, now log off your computer and login back, you will no longer see the low disk space alerts. This registry tweak works on Windows XP, Vista and Windows 7. Enjoy!
