SHRINK C VOLUME TO SMALLER CAPACITY

I have the same issue. I have a brand new HP Envy 17t laptop and have put no files or apps on it. I tried to use Disk Management to shrink the C: system volume but it would only allow 50% shrink. I moved the pagefile.sys and swapfile.sys to another physical
drive, E:, but this made no difference. I can still only shrink the C: volume to 50%.

Perhaps the only solution is to use a third-party partition editor like easeus or mini Partition Editor.

If you have any other suggestions, let me know.

Thanks!

Shrinking a volume

Thanks, Stefano. At your suggestion I did a Defragmentation on the drive I want to shrink. That took almost a day on a 1 TB drive. The drive is now 0% fragmented. But still I'm getting "wrong perameter" when I try to shrink the volume. Here's a screenshot
of the dialog window for shrinking the drive:

The amount of space I last put in to shrink was 50012. Any idea why that didn't work?
