Windows 7 install takes up 70GB - is this normal

I installed Vista and later added Windows 7 32 bit Home Premium in dual boot mode. Each one took 70 gb . I can not believe this is normal. Any advice ?

It's not normal.

Post a screen shot of Windows Disk Management.

Did you use an ordinary retail installation disc purchased from a retailer like Best Buy or Newegg? Or did you use a burned disc? Or?

just a guess:

If you installed into a partition that had a different Windows system on it before, look at the Windows.old folder.

my win7 64 instal takes 36GB and that includes at least 6 GB of my own programs and data to give you some idea. Also as a general rule 32bit instal should take less space than 64.

Amazing

You should delete windows.old in c drive folder to free the space

oh... one more thing....

If you have a lot of RAM, it seems that Windows will automatically allocate the same size as your page-memory-swapping file: pagefile.sys. It is a hidden file.

Also, if you have hibernation enabled, you can control how big of a file this should be... (pretty sure). At any rate, Windows will allocate gigabytes for this as well.

For example, if you issue the top command in your C:\ root directory

Code:

 
C:\>dir *.sys/a:h
 Volume in drive C has no label.
 Volume Serial Number is 8782-E190
 Directory of C:\
05/18/2014  03:49 PM     6,353,817,600 hiberfil.sys
05/18/2014  03:49 PM     8,471,760,896 pagefile.sys
               2 File(s) 14,825,578,496 bytes

You will probably see something like the above.... 6Gig for Hibernation and 8Gig for the Page swap file.
