Determining disk space usage on a Mac can be a bit of a struggle. This utility does a nice job!
DaisyDisk scans your disks and presents their content as interactive maps where you can easily spot unusually large files and remove them to get more free space. The map gives you an overview of your data, so you always know what your hard disks are filled with.

Sometimes computer repair in San Diego can be quite a task. Now this will work in multiple situations, but I've found it to be most effective when working with a server in which the user does not have admin rights. First click Start then in the search bar type regedit right-click on the result and choose run as administrator. Enter the requested Username/Password if required.
Once in the registry as an admin navigate to HKEY_ CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Find your printer's name. ex. Brother MFC-7440N Printer (This can be found under Start>Devices and Printers. Copy the name down exactly as displayed. There will be something on the end of the Printer name. ex. Brother MFC-7440N Printer (Copy 1),winspool,Ne03: This signifies it as a network or local printer if leaving it as is does not work change it to Ne00 for a network printer or LPT1 for a local.
If the key gives an error about being unable to be changed Right-Click on the Windows registry key, click permissions and add your username with full control to the key.
Lastly, if the defualt still cannot be changed check the other users ex. HKEY_USERS\S-1-5-21-3496027142-1497543067-2469998129-1145\Software\Microsoft\Windows NT\CurrentVersion\Windows and repeat the process for each user there.
We have just began our video tutorial series and in this episode we will be looking at how to optimize Windows 7 startup as well as how to make sure you are getting the correct internet connection speed.
At Mobile Computer Wizard we use some great boot cd password removal utilities such as Offline Password Changer that, unfortunately, don't always work on certain retail machines. This is because some retailers install the OS over modified versions of NTFS making it impossible for the aforementioned utilities to locate and edit the Microsoft SAM (Security Accounts Manager) database where the account password info resides. The following password removal technique allows you to edit the SAM database via command line by exploiting a security loophole with Windows Accessibility, which was designed to help disabled people to log into Windows. This also bypasses the complication of locating the SAM database from outside of Windows by allowing Windows to find it for you.
The first thing to note is at the login screen, the Windows + U hotkey launches Utilman.exe, which resides in Windows\System32 directory. The trick is to replace this with cmd.exe to give you command line access at the login screen. You can modify these files from a boot cd, such as UBCD or Hiren's, or even the OS install disc's "Repair Your Computer" option (gives you command line access). Alternatively, you can pull the drive and hook it up to another system. If you use the "Repair Your Computer" route you will need to use the following commands for the Utilman.exe and cmd.exe swap:
cd windows\system32
ren utilman.exe utilman.exe.bak
copy cmd.exe utilman.exe
Otherwise, use roughly the same method. Rename utilman.exe, make a copy of cmd.exe and rename it to utilman.exe.
Once the tricky part is done, boot the system up and let it go to the login screen. Windows + U should now launch the command line interface. Reference the following commands for methods of access.
Reset Password
Warning: You will need to adjust/remove permissions to gain access to their files again.
net user JohnDoe hunter2
This will change the password for account JohnDoe to hunter2. If the account name has been changed so that Windows is not displaying the true account name, you can display a list of accounts with the following:
net user
Create a New User Account
This will create a new user account (UN: NewGuy, PW: abc123) and give them admin privileges.
net user NewGuy abc123 /add
net localgroup Administrators NewGuy /add
Revert Changes
cd windows\system32
del utilman.exe
ren utilman.exe.bak utilman.exe
Then reboot system.
net user NewGuy /delete
For removing the new account.
