How can I free up some space from my Windows PC drive C?

You might need to upgrade a few hardware items first also you might upgrade to vista then windows 8
Creating a new partition on your hard drive gives your future version of Windows 8 a place to live on your drive.
Knowing exactly how much space the OS requires helps you determine how large to make your partition.
Size requirements don't tell the entire story on their own, though.
Other factors like drive type and additional storage help ensure you get the best Windows 8 experience where your hard drive is concerned.

Size Requirements
Both Windows 7 and Windows 8 have the same system requirement regarding hard drive space, so if your hard drive can handle Windows 7, Windows 8 shouldn't be a problem.
For 32-bit versions of the operating system, you'll need at least 16 GB of available disk space. The 64-bit version requires 20 GB.
Your partition will have to be at least one of these sizes, depending on your OS version.
The PC Advisor website warns that these are literally the bare minimum requirements, and using these figures leaves you hardly any space to save files and install apps or programs.
Size Recommendations
You'll get more out of Windows 8 if the operating system has enough free space for you to install your favorite programs and apps.
PC World calls this extra space "breathing room," suggesting you give your Windows 8 partition at least 30 to 40 GB.
If you're dual-booting with another operating system or you're accustomed to keeping excess data on a separate partition, 30 to 40 gigabytes should be fine.
If you'd rather have all your songs, videos and PC games on the same partition as the operating system, consider giving it substantially more space.
Solid State Drive
Windows 8 works on traditional hard drives with spinning disks, but it's optimized to run on a solid state drive.
If you've got an SSD, consider putting your Windows 8 partition on that drive.
While any operating system benefits from the speed increase an SSD brings, ARS Technica specifically recommends this drive type for Windows 8, saying the operating system's "tablet-esque feel and search-heavy usage model will be much better served by solid-state storage."
Other Requirements
Hard drive space is a crucial system requirement, but others are just as important.
Ensuring your computer meets the other requirements before partitioning your drive for Windows 8 saves trouble in case your computer can't handle the OS.
You'll need at least a 1 GHz processor that support PAE, SSE2 and NX.
Your computer has to have at least 1 GB of RAM for 32-bit Windows 8, or 2 GB for 64-bit.
Your graphics card must be at least a DirectX 9-capable card with a WDDM driver. Also, while you're formatting your drive, format the Windows 8 partition in the NTFS format.
Storage Spaces
Storage Spaces is a useful Windows 8 feature when you're working with multiple drives and partitions.
The tool enables you to group drives into one larger storage space so you don't have to constantly switch partitions and explore different drives.
For example, if you create a storage space between two 32 GB flash drives, you'd be able to access it as if it were one larger 64 GB drive.

You need to delete items to free up space. Not much else, but maybe run a defrag and disk cleanup.

proceed according. God bless you

1. Create a New Partition
   • 1 Launch the Disk Management tool on your computer running Windows 7 by opening the Start menu and typing "diskmgmt.msc" in the search bar. The Disk Management tool, showing all connected storage devices, appears.
     
   • 2 Pick the hard drive onto which you'll install Windows 8. The normal choice is Disk0, which is the primary hard drive. This disk should already show your C: drive, and possibly other items like recovery partitions.
     
   • 3 Verify the available free space on the selected disk. For most computers with no other dual-boot setups installed, the entire drive should be occupied, so you'll have to shrink an existing drive (like C:). If there is a section with a black bar titled "unallocated," then this represents free space not currently in use.
     
   • 4 Shrink your C: drive by right-clicking on it and selecting "Shrink Volume." The computer assesses and reports how much free space is available on the disk. You need a minimum of 16GB of free space to install 32-bit Windows 8 and 20GB of space for 64-bit Windows 8. Type either 160000 or 200000 in the "Enter the amount of space to shrink in MB" box. Increase that number if you want additional storage space for files and programs within Windows 8. Click "Shrink" to continue.
     
   • 5 Right-click on the new unallocated space and select "New Simple Volume." Leave the defaults, ensuring that NTFS is selected as the file system type. Give the drive a name, like "Windows 8."
     
   • 6 Insert your Windows 8 installation disc or USB drive into your computer. When the new drive is formatted, restart the computer and boot from your installation disc or drive.
     
   Install Windows 8
   • 7 Select "Custom" during the Windows 8 Setup initialization process.
     
   • 8 Select the new drive you created when the installation program asks you where you want to install Windows 8. Be sure to select the drive with the label you used for the new drive; if you install to the C: drive, you will overwrite your existing Windows 7 installation.
     
   • 9 Follow onscreen instructions to install Windows 8.
     
   • 10 Reboot after you install Windows 8, ensuring that you've removed any installation media. When the computer restarts, you are presented with a boot screen that lets you pick between Windows 7 and Windows 8.
     

Hey, You got to free space on your hard drive. The virtual memory resides on your hard drive. but if the hard drive is getting full, this will reduce the virtual memory. So make home for virtual memory by free space on your hard drive.

That is usually caused by the laptop switching off improperly.
Run safe mode first and then when it has finished close down and restart is normal mode.

You need uninstall programs that you don't use. This way you can free up some memory RAM. Also install a free program Advance Care _select free version- at download.com.

The swept files are stored up in folders you might not see.

Run disk clean up and you will have more spaces wherein all temporary files will be deleted.

Cheers.

Rate this please

it could be because of system reservation for page memory and system restore information. You can use CCleaner to clean up to get more free space.

just move your music and pictures to the other hdd as windows updates will only download and install on the drive that windows is installed on

1. right click on C: Local Disk ( your C drive )

2. click properties

3. look at the amount of used space in blue , and free space you have in pink

to free up more hard drive space

Go to the add/remove programs in control panel

Look for programs that you don't need and uninstall them.

then run the windows disk clean up utility.
