• My windows 10 upgrade consumes all of it's drive c: space (50 GB)
• I am unable to install the update,
• I suspect the windows 10 need this much space and it is some kind of glitch,
• Please suggest a way to free up some space as I don't prefer to format partition C:

 

ADDING 50 GB Unallocated Space to (C Drive as It Runs without DISK Space

Dear Sir. Thanks for Your Answer of My Problem. But It Is A Matter of Great Regret That These Steps don't Solve My Problem.. After I Right Click on (C Driive "Extend Volume" don't Function and As A Result " Extend Volume WIZARD" Don't Appear.

I Use Latest Version of Windows 10. My (C at now is Out of Any Disk Space. As A Result My PC RUNS TOO SLOW TO WORK.

I Always Work As Freelancer. But My Work is Hampering Much for Want of Adequate Disk Space on My (C Drive.

Please take an IMMEDIATE ACTION to ADD 50 GB Unallocated Spacce to (C DRIVE of My PC.
