How can I free up some space in my C: drive?

I am running Windows 8 on a seperate partition right now, and want to delete everything on my old partition that contains Windows 7, except for the Windows 7 OS (just in case). How can I do this?

Your question is rather ambiguous. Are you trying to uninstall programs on the Win7 partition, or delete files, or what? What is the purpose of deleting "everything"? – Force Flow Apr 1 '12 at 3:18
I want to free up disk space, so that I can allocate the free space from the Window 7 partition and merge it with my Windows 8 one. I just want to keep the Windows 7 install, just in case anything goes wrong. – Help Apr 1 '12 at 3:19
Use disk imaging software and make a image of the W7 partition and mbr. Now you can delete everything, if things go bad you can restore the image you made to that partition. – Moab Apr 1 '12 at 4:16

  1. Uninstall all the items using Revo Uninstaller.
  2. After doing that, create a new user account and delete the rest in the

    C:\Users folder

  3. Run CCleaner
  4. Finalize a service pack of Win 7.

Why can't he just uninstall using Windows' Programs and Features? – Lèse majesté Apr 1 '12 at 4:18
@Lèsemajesté Revo Uninstaller does the job better – HackToHell Apr 1 '12 at 6:43
In what ways does it do it better? – Lèse majesté Apr 1 '12 at 7:07
@Lèsemajesté Removes stuff from registry that the uninstaller fails to remove, clears the Appdata .. – HackToHell Apr 1 '12 at 7:08

I would just delete everything and reinstall the Windows 7 partition (don't install anything yet), defrag, then select the partition size. On my box, I have like 200g of free space in my Windows partition because I installed programs before I partitioned the drive, and there were some unmovable files. To prevent this error in the future, I am always going to reformat the entire drive, and leave a few partitions free for changes in the future.
