(Win2k, XP, Vista) Using NET USE in a batch file at login to force-connect mapped drives… useful for situations where mapped drives mysteriously disappear (this script can safely be re-run repeatedly) or to prevent conflicts between network shares requiring conflicting credentials.

(Requires Win2k, XP, or Vista) Using FOR at the command line to step through every subfolder in a given folder, and create new folders with those names in a different parent folder.

Suppose you have a group of folders under C:\test1, like this:

C:\
|
+-test1
  |
  +-folder1
  |
  +-folder2
  |
  +-folder3

And you want to create a new test2 folder under C:\, which will contain emtpy folders with the same names as those in test1, like this:

Windows tries very hard to prevent you from replacing or deleting critical system files, even something as mundane as notepad.exe.

Note that this behavior is designed to keep your system functional whenever a critical file is accidentally (or maliciously) deleted or modified, and any actions you take to modify your system at this level, even with the best of intentions and what may seem like reliable information, may very well cause unexpected results to occur, such as an unstable or unbootable computer, or even lost data. BACK UP YOUR DATA REGULARLY, especially before attempting modifications to your operating system files, and make sure you have a backup of your operating system to fall back on in case something goes wrong.

Suffice to say, there is a relatively simple way to bypass Windows file protection. In fact, there are two very different methods for XP and Vista due to the way they protect operating system files:

You can start Windows normally, but your computer can’t / won’t / doesn’t boot into safe mode - either the computer reboots itself after listing the drivers, or you get a BSOD (Blue Screen of Death) with a STOP 0×0000007B error - generally after a virus or trojan infection. To confirm this solution might work, in Registry Editor go to HKLM/System/CurrentControlSet/Control/SafeBoot. If it’s not there, or there are only a few empty keys, then something has wiped/corrupted your safe mode configuration to prevent you from entering safe mode where you can run a more thorough malware disinfection.

Apparently there’s an oft overlooked trend in motherboard manufacturing: despite chipset and component cooling solutions growing ever more massive, these heatsinks continue to be secured to the board with cheap, unreliable plastic pins. Luckily these can be replaced with machine screws with minimal effort.

(Applies to v3.1.0.15) DynDNS Updater is a simple, free to use dynamic DNS utility: it automatically detects changes to your external IP address - such as when your ISP renews your DHCP lease - and forwards this information to your DNS service provider to ensure your domain name always points to your most current IP.

However, this utility is distributed by DynDNS.org (although designed and supported by third party Kana Solution) primarily to support the use of their specific service. But with a little tweaking, you can make this well-designed utility work for other service providers - for this example we’ll be using the domain registrar Namecheap.com, one of the better rated affordable service providers.

IE is leaving room for ascenders and descenders on characters within the elements - even if there is not text present. To workaround, set the element (div or table cell)’s properties like such:

font-size: 0px
line-height: 0px

Perhaps changing the content’s vertical-align property (to middle?) might also help…
