Basically the title of the topic says it all but I'll fill you in on all the details. I have a WD blue 7200rpm 500GB HDD. Partitioned into drives C and D and was wondering if I could shrink down D and increase C.

BTW the guy who partitioned my drive did it weird. My drive in my laptop is partitioned but its in equal sizes i.e. they're both 250gb each. When the guy who assembled my rig partitioned the drive for me it became 195 (C) and 270 (D). Where the heck did the remaining 35GB go? Is it the OS? If it is then I'm still weirded out cause when I first opened my desktop a lot of the HDD space for C was still occupied or is that bloatware that comes with Windows 7 Home premium?
 
First, you did NOT loose 35 GB. A "500 GB drive" has 500,000,000,000 bytes available. But Windows defines "GB" to mean 1024 x 1024 x 1024 bytes, or 1,073,741,824 bytes. If you divide that number into the actual byte count, Windows will tell you your HDD has 465.66 of these "GB". It's a difference in how the HDD makers and the Windows makers think of the term "GB". You have 466 of the Windows' version of GB on your HDD, but the good news is those "GB" are a little bigger than you thought.

Now, back to your real issue - how to use some of the space from D: to make C: bigger. You would have a lot of difficulty doing this yourself with the tools that Windows itself provides. BUT third-party utility suites like Partition Magic as ahnilated suggested, CAN do that job for you - you just have to buy the software, install and use it.

BIG HINT: doing this kind of work includes a small risk that something can go wrong and you will lose EVERYTHING on your HDD. So, back up both Partitions on your HDD before starting, just in case.
 
Why don't you uninstall the programs you don't need?

A Windows installation takes about 5-10 GB, 15 max. If your 195 GB system partition is full, what is on that 180 GB? Installed programs? Downloaded files (why not just move those to the D partition)?

An easy way to find this out is to order the installed programs by the size they take. Control Panel, Programs, Programs and Features, then click on the word "Size" in the table header.
 


About that why dont games register their size? like Skyrim and so on
