3 ways to Free up unnecessary used HDD space on Windows 7

NOTE: These methods work best for systems that have a large amount of memory (RAM).


1. Hibernation Reserved Space

Hibernation reserves HD space up to the amount of memory your system has. To disable hibernation and recover that drive space then type the following command with administrator privileges in cmd.exe.

powercfg -h off

2. Decrease Virtual memory

Similarly to hibernation the system page file or virtual memory also reserves HD space up to the amount of memory your system has. This shouldn’t every be disabled, but you can reduce it to a more reasonable size especially if you have over 4GB of memory. Follow the steps bellow.
  • Right click “Computer” and click “Properties”
  • Click on “Advanced system settings” in the left column
  • In the “Performance” section, click on “Settings”
  • Go to the “Advanced “ tab
  • In the “Virtual Memory” section click on “Change”
  • Uncheck “Automatically manage paging File size for all drives”
  • Chose the “Custom size” radial button
    • set the “Initial size (MB):” to 512
    • set the “Maximum size (MB):” to 1024
  • Restart your computer for changes to take effect

3. Remove Service Pack 1 backups Thanks Alan McBurney

After installing Service Pack 1 about 4GB are used to maintain backup files. If you are certain that you will never need to revert back before SP1 then you can free up this space by typing the following command with administrator privileges in cmd.exe.

DISM /online /Cleanup-Image /SpSuperseded

My First Car

1980 Mercedes Benz 300D
It was one of those cars that you buy from your parents because you don’t have any money. Since it was such an old car it is a collectors item. If only it was in mint condition I could have sold it, or traded it, for half the price of a new car. So aside from that I was fixing this car every week for the first two months I owned it. I really didn’t know much about auto repair other than what I learned in my small engines class in high school. But to me mechanics have a sense of order to them and I can generally figure things out. It just takes me longer than someone who has the know-how. Most of the repairs were relatively small such as vacuum lines leaking and starter problems among other things. Eventually, it was able to go for a month or two before problems would come up again. The biggest job was when the starter chewed up enough of the flywheel that  it wouldn’t turn over the engine. As a quick-fix, I would just take a screwdriver crawl under the car and move the flywheel a few inches to get past the chewed up part.
  
But I wasn’t about to do that for very long. To properly fix the car I was either going to have to drop the transmission or raise the engine to replace the flywheel. Lucky for me, my dad had 300TD Mercedes just sitting around with a good engine for parts. Since I was going through all the trouble to raise the engine and since the other car was a turbo model with an almost identical engine, I might as well swap engines. I was excited to have a turbo diesel because that really makes a difference in acceleration. It took me about two weeks to complete the job with some help from my dad in hoisting the old engine out and dropping the new engine in. Everything seemed to work fine, for the most part. It was having some trouble shifting. Since I knew nothing about transmissions and I wasn’t about to try and rebuild a transmission on my own, I decided to spend a bit of money and have a professional take a look at it. The company called Gunbarrel Import Motors in Niwot, Co is an excellent mechanics and dealers. They are a bit expensive, but you get what you pay for. I finally had a car that was running well. And while It still had a few things that needed fixing, it served me well as my first car.
