How To Safely Eject Your USB Devices From the Desktop Context Menu

sshot-3
If you are one of those people who don’t safely remove their USB Devices just because you’re lazy, here’s a neat trick to do it from the context menu on your desktop. Even if you are not lazy and just forget, the icon will serve as a mental reminder. So let’s take a look.

The Safely Remove Hardware Dialog Method

This method will bring up the Safely Remove Hardware dialog box, from there you can choose which USB device you wish to eject. If you are looking to eject a specific USB drive take a look at the next section.
Press Win+R to bring up a run box and type regedit to open the registry.
sshot-25
When the registry is open, navigate to
HKEY_CLASSES_ROOT\DesktopBackground\Shell\
sshot-26
Right click on the shell key and create a new key called Safely Remove Hardware.
sshot-27
Once the new key is created, create a new string value, and call it Icon.
sshot-28
Double click on the icon string, in the Value data field type the following:
hotplug.dll,-100
sshot-29
Now right click on the Safely Remove Hardware key that you just created and create another key,  this time name the key command.
sshot-30
Once the new key has been created select it to open see the keys values.
sshot-1
This key will have a value called Default, double click on it to edit it, in the Value data field type
C:\\Windows\\System32\\control.exe hotplug.dll
sshot-2
That’s all there is to it if you want the Safely Remove Hardware dialog to appear.
sshot-3

Ejecting a Specific USB Drive

If you are looking to eject a drive with a specific name or drive letter then this method is better suited for you.
Extract the file somewhere (for illustration we’ll extract to the root of the C:\ drive), then right click on the file, select properties, and click the unblock button in the bottom right hand corner of the dialog.
sshot-5
Press Win+R to bring up a run box and type regedit to open the registry.
sshot-25
When the registry is open navigate to:
HKEY_CLASSES_ROOT\DesktopBackground\Shell\
sshot-26
Right click on the shell key and create a new key called Safely Remove USB.
sshot-27
Once the new key is created create a new string value, and call it Icon.
sshot-6
Double click on the icon string and in the Value data field type the following:
hotplug.dll,-100
sshot-29
Now right click on the Safely Remove USB key that you just created and create another key,  this time name the key command.
sshot-7
Once the new key has been created select it to open see the keys values.
sshot-8
This key will have a value called Default, double click on it to edit it. Here we have a few options, which ever method below suites you best should be typed into the Value data field.
Note: Remember to replace the name or drive letter in the following example to the name or drive letter of YOUR USB device.
We can either eject a USB with a certain name by typing.
C:\usb_disk_eject /removename “Memorex USB”
We could also eject a USB with a certain driver letter, in my case drive G.
C:\usb_disk_eject /removeletter G

How to Manually Repair Windows 7 Boot Loader Problems

If you’re having boot problems on your Windows PC, it’s often helpful to repair the MBR (Master Boot Record) to restore the Windows 7 boot loader—and you can do it easily from the Windows installation disc.
This is generally most useful if you’ve broken something and there’s a boot loader error, or if you have made the mistake of installing an older version of Windows on the same PC that already has Windows 7 which wipes out the boot loader.

Boot From the Windows Install Disc

The first thing you’ll need to do is boot off the install disc, and then click through until you see the “Repair your computer” link in the lower left-hand corner.
image
You’ll need to choose the correct installation of Windows and then click the Next button.
image
And then you’ll get to the System Recovery Options screen, where you can get to the Command Prompt.
image

Repairing the Master Boot Record

If you want to restore the master boot record, you can simply type in the following command:
bootrec /fixmbr
You can also write a new boot sector onto the system partition with this command (which is often more useful):
bootrec /fixboot
And of course, if you just use bootrec /? you’ll be able to see all the options.
image
This is the same way that we fixed the “BOOTMGR is missing” error when trying to boot up Windows 7 or Vista.

Replacing the Windows XP Bootloader with Windows 7

If you’ve managed to install XP on the same PC that you already had Windows 7 on, you’ll noticed that you can’t boot into Windows 7 anymore. You can use this command to fix that and restore the Windows 7 bootloader:
bootsect /nt60 all
Depending on the partition that you’ve installed, you might need to substitute the drive letter instead of “all”.
image
Note: if you want to restore Windows XP back to the menu, you can open up a command prompt in Windows 7 and run this command:
bcdedit /create {ntldr} -d “Windows XP”
image

Using the Automated Startup Repair

Of course, all this command-line stuff is probably not necessary in most cases. You can usually just use the Startup Repair option from the Recovery menu…
image
It’ll check for problems and probably fix them. If not, then you can always use the command prompt.

Have you ever needed to restore your boot loader to get Windows working again?

How To Manage Partitions on Windows Without Downloading Any Other Software

undefined
There are tons of third-party partition managers for Windows, but did you know that Windows includes its own partition manager? Microsoft did a good job of hiding the built-in partition manager, but it’s there.
You can use the Disk Management tool to resize, create, delete and format partitions and change their drive letters — all without downloading or paying for any other software.

Accessing Disk Management

The quickest way to launch the Disk Management tool is by typing “Partition” into the search box in the Control Panel or Start menu. Just click the “Create and Format Hard Disk Partitions” option that comes up.
undefined
You’ll see a window divided into two panes. The top pane shows you a list of your partitions, referred to as volumes, and the bottom one shows you a graphical representation of your storage devices.
undefined

Resizing a Partition

Right-click a partition in either pane and select Extend Volume or Shrink Volume to resize it. Other options for manipulating partitions are also located in the right-click menu.
undefined
Extending and shrinking have some basic limitations. You can only shrink a partition if it has enough free space, and you can only extend a partition if it has unallocated space to the right of it on the same drive. You’ll see empty, unallocated space to the right of a partition if you can extend it. Windows can’t extend a basic partition to its left; you’ll need third-party software for that.
Creating a Partition
Once you’ve shrunk a partition, you can use the free space to create another one. Just right-click inside the unallocated space and select New Simple Volume
undefined
You’ll see the New Simple Volume wizard, which guides you through setting a size for the partition, assigning a drive letter and formatting it with a file system.

Deleting a Partition

You can also right-click a partition and select Delete Volume to delete a partition and free up space. This option deletes every single file on the partition; be careful when using it!
undefined

Changing Drive Letters

Right-click a partition and select Change Drive Letter and Paths to change its drive letter. Click the Change button to select a new drive letter.
undefined
You can use this dialog to assign a permanent drive letter to a removable drive or remove a partition’s drive letter and hide it.

Formatting a Partition

Use the Format option in a partition’s right-click menu to format it with a new file system and erase its contents. You’ll lose all files on the partition if you do this!
undefined
You can also format partitions by right-clicking them in Windows Explorer and selecting the Format option.

How To Lower the Critical Battery Level to 1% in Windows 7/8

banner
With specific hardware configurations, Windows refuses to let you change the Critical Battery Level below a specific point. If you’ve got a big battery, this prevents you from using every last bit of juice. Thankfully, there are two easy workarounds.
We’ve already shown you How To Tweak the Low Battery Action on Your Windows 7 Laptop, but Windows can be stubborn. On my particular laptop, it won’t let me set the critical battery level to anything below 5%; it changes back to 5% as soon as I click something else. On my netbook, that’s close to 20 minutes I’m missing out on, and it takes less than 30 seconds to hibernate so I know I would be fine with 1%. Depending on your specific hardware this number may be different, or you may be lucky and not have this problem at all; it appears that many Macbooks running Windows 7 don’t have this issue. If you’re like me, however, there are two solutions you can choose from: one that’s easy and another that’s slightly more involved.

Pull the Battery

Plug in your laptop so that it’s drawing power from the wall. You can pull the battery on the live system this way without any problems. Once the battery is removed, you should be able to change the critical battery level like normal, only this time your settings won’t change back. When you’re done, just put the battery back in.
power options
This doesn’t appear to work on all systems. If you tried this and it didn’t work, the next solution will.

Use Powercfg.exe

If your laptop doesn’t have a user-replaceable battery, or for whatever reason you can’t remove the battery while the system is on, you’re not out of hope yet. We can set the lower percentage manually using the command-line utility Powercfg.exe, so go to Start > All Programs > Accessories > Command Prompt.
First, we need the GUID of your power scheme. Input the following command:
powercfg.exe –l
That’s an ‘l’ as in “list,” which is what powercfg will do.
powercfg list
Your currently active power plan will be marked with an asterisk. I only ever use the first one, but if you switch power plans, you’ll need to go through this process for each one. Find the one you want to change in the list, right-click, and select “Mark.” Now you can select the long alphanumeric string with your mouse cursor, and then hit the Enter key to copy it. You should paste this in a notepad window, because we’ve got more to copy.
Next, we need the GUID of the subgroup and the setting we’re looking to change. Run the following command and replace “[SCHEME_GUID]” with what you just copied.
powercfg.exe –q [SCHEME_GUID]
You’ll get a low of text in the command prompt. Scroll through it and look for “Critical battery level.” First you need to copy the long alphanumeric string that belongs to the subgroup “Battery,” which you can find a short ways above “Critical battery level.” Paste that in your notepad window. You’ll next need to copy the GUID for the setting, which is right next to “Critical Battery level.” The following screenshot highlights the section to look for in red and the two GUIDs you need to copy in cyan.
powercfg query
Now we have all of the pieces we need to build our command:
powercfg.exe –setdcvalueindex [SCHEME_GUID] [SUBGROUP_GUID] [SETTING_GUID] [VALUE]
Fill in the Scheme, Subgroup, and Setting GUIDS from your notepad window and replace “[VALUE]” with your desired percentage. Hit the Enter key to set it. Here’s the command I used for my particular needs:
powercfg.exe -setdcvalueindex 381b4222-f694-41f0-9685-ff5bb260df2e e73a048d-bf27-4f12-9731-8b2076e8891f 9a66d8d7-4ff7-4ef9-b5a2-5a326ca2a469 1
This will set my critical battery level when on battery power to 1%. If you want to also change the setting for when you’re on AC power as well, just hit the Up key in the command prompt (to bring up your previous command) and change the
-setdcvalueindex
option to:
-setacvalueindex
That’s it! Now you can squeeze every last possible minute out of your battery, whether Windows wants you to or not!
