36 GB for C: ?
36 GB is simply NOT big enough for Win7 SP1 x64, unless it is a brand new installation.
Even if you go to the trouble to install every single program on another drive, C: will still run full with just the stuff that Windows needs to store (for technical reasons) in C:.
Every WindowsUpdate, every other program that is installed, will somewhat increase the space needed on C:. (Some programs require more than others. Some just can't be installed anywhere else but on C:.)
This means that C: will keep growing slowly ALL THE TIME.
Even if you use a C: drive with ample space, if the Windows installation lives long enough eventually it will fill up.
Please... Resize the volumes and make C: at least 50 GB.
If you use hibernate add the size of the physical RAM to this 50 GB (e.g. for a 8 GB machine use 58 GB for C:.). This is to accommodate the (hidden) hibernate file in which Windows saves the hibernate state.
This 50 GB is a rule of thumb value that for most people will mean they can operate Win7 for 3-4 years without C: running full.
You still need to take care to install very big programs (like games that are often several GB size) on another volume.
The free space will automatically return once the data in winsxs is no longer required – Ramhound – 2014-03-14T19:12:58.003
So she has a single hard drive with multiple volumes and the OS volume is 36GB? Why are people still doing this kind of thing? I thought this craze died out years ago. Shrink the other volume and extend the OS volume. – joeqwerty – 2014-03-14T19:44:05.253
