Windows 10: Deleting hiberfil.sys during startup

Background: I'm having issues with the latest Windows update (not sure what the update code was since I didn't pay attention to that, but I think it was the March 2021 Cumulative Update). For reference, my PC has attempted installing this update every time I shut it down for the past week, and has failed every time for reasons it won't tell me. I'm currently going through different options to recover but none have worked. I am now considering using Robocopy to copy my main C: drive onto an external D: drive and then resetting my PC.

Problem: When I try using Robocopy to copy my C: drive to my D: drive, I get an error, "Error 5: (hex for 5) Copying File C:\hiberfil.sys Access is Denied". I cannot use the usual command "powercfg -h off" to disable hibernation mode and get rid of the file during startup, so now I'm stuck trying to figure out how to safely get rid of it. Would anyone happen to know how to fix this issue?

Also, if there's any better options, please do let me know. I've already tried DISM but that gave me an error saying I cannot use "/Online" during upgrade or something like that.

Thanks in advance!

Deleting Hiberfil & Pagefile

Howdy,

So I have a 60gb SSD with Windows 7 and Office on it (all specs are listed <--- under my username). I have a 12gb pagefile and a 9gb hiberfil, is it possible to delete those or make it so that hiberfil at the very least is no longer created? I just want a little free space on there for future use.

Thoughts?

 

Deleting Hiberfil & Pagefile

Pagefile size depends on RAM, just find optimal value and stick to that.

If you use SSD and want more free space then disable System Restore. It is far more efficient than disabling hiberfil

After disabling hibernation hiberfil.sys gets deleted automatically.

 

Deleting Hiberfil & Pagefile

You would have to move your Page File to a different drive to get rid of that file, however you can make is smaller by adjusting the size in Windows.

To get rid of Hyberfile.sys you need to disable hibernation by doing the following:

• Click Start, and then type cmd in the Start Search box.
• In the search results list, right-click Command Prompt, and then click Run as Administrator.
• When you are prompted by User Account Control, click Continue.
• At the command prompt, type powercfg.exe /hibernate off, and then press ENTER.
• Type exit and then press ENTER to close the Command Prompt window

Then you can delete the hyberfile.sys file.
