Windows 10: how can when i save 50 GB to a 80 GB hard drive, it will change to 17 GB free? Need advice.

I transferred around that amount of files from a failing hard drive to an external drive, to a new hard drive. i am also finding that windows updates are probably doing part of this.Not sure what to do about the space. some updates are security updates. this system's main hard drive is only 236 GB hard drive. i believe the last system only had one hard drive and it probably was a terabyte. it never was completely used. nevertheless, it wasn't full. This system has about all the same files, yet some stuff to substitute old things. I also think some things are not installed, and some may not be

My windows 10 upgrade consumes all of it's drive c: space (50 GB)

• 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:

 

The CBS file going over 50 Gb

Hello, i have a liitle problem with running out of space in my C: partition.

So a few days ago, i got a notify that i do not have enough space in my C partiton, and it was right i only had 5 GB free out of a total 100 GB. I started searching file by file and in C:\Windows\logs\CBS i found a rather intersting text file with over 50
GB worth of data that i couldn`t open becouse the text is to large.

I tried deleting the file by stoping TIWorker and Windows Modules Installer. And so i got rid of those 50 gb of data, after a restart i saw that the CBS text is at 30 Gb and still raises so i tried some other method while i searched for this problem but with
no definitive results, the file keeps coming back with a size of 300 MB and then raises to 40-50 gb

Unable to shrink the C drive beyond 455 GB

I was trying to partition my 1 TB hard drive in new windows 10 laptop from HP by using disk management tool . I would like to keep the following partition sizes:

C Drive : 200 GB

D Drive : 400 GB

E Drive : 300 GB

However I am unable to proceed as the shrink cannot be beyond 50% and it doesn't allow Volume C to be less than 455 GB.

Will I be able to successfully shrink it to 200 GB in c drive and does it have any disadvantages doing so?
