Where’s my Hibernate option in Windows Vista?

I was really greedy when I opted “Hibernate File Cleaner” to save 2 GB of space in my C drive. I rarely use hybernate option. 

I thought Windows would cleanup 2GB space and takes it whenever necessary (if I opt hibernate). But I was wrong. Soon after “Hybernate” option went out from system start menu on opting “Hybernate File Cleaner”. I searched over the whole control panel to get an option to re-enable hybernate in my machine. But I wasn’t lucky enough

Finally a google search blessed me with a KB article.

So how you can re-enable Hybernate option if it’s not there?

1. Click Start, and then type cmd in the Start Search box.
2. In the search results list, right-click Command Prompt, and then click Run as Administrator.
3. When you are prompted by User Account Control, click Continue.
4. At the command prompt, type powercfg.exe /hibernate on , and then press ENTER.
5. Type exit, and then press ENTER.
6. If you give powercfg.exe /hibernate off will make Hybernate option unavailable.
