hiberfile.sys is a huge file normally found in your Windows root directory. Normally it’s a file 75% size of your total amount of RAM. So if you have 32GB installed, you’ll have a 24GB hiberfile.sys file sitting there taking up space for no reason.

If you can live without the hibernation feature (this is more the case for desktops – hibernation is actually quite useful for laptops) then you can disable the feature and remove the file with this simple DOS command:

powercfg.exe -h off

Just remember to launch the  command prompt and “Run As Administrator”.

To remote shutdown a workstation in 5mins from now:

shutdown /s /t 300 /m \\EWEAW00020

To cancel the command:

shutdown /a /m \\EWEAW00020

When you install Microsoft Office, by default it will leave a folder of installation files on the C: drive. You cannot delete this folder because every time MS Office needs to update itself, it uses those files.

With the MS Office 2013 edition, I have a folder with 830MB of files! On a small SSD, this is precious space that needs recovering. So what to do?

One trick I came across today is to move those files to another disk and create a symbolic link to them:

mklink /D "C:\MSOCache" "D:\MSOCache"

And that’s it!
