According to MSDN : On Windows 7 and on Windows Server 2008 R2 with the Wireless LAN Service installed, the operating system installs a virtual device if a Hosted Network capable wireless adapter is present on the machine. This virtual device normally shows up in the "Network Connections Folder" as "Wireless Network Connection 2" with a Device Name of "Microsoft Virtual WiFi Miniport adapter" if the computer has a single wireless network adapter. This virtual device is used exclusively for performing software access point (SoftAP) connections. The lifetime of this virtual device is tied to the physical wireless adapter. If the physical wireless adapter is disabled, this virtual device will be removed as well. On Windows 7, there's no UI to start or stop SoftAP....

My C drive was seriously fragmented with about 20% free space. So I ran the built-in Windows disk defrag utility. To my surprise it doesn't work at all! I tried to defragment multiple times and every time it comes back without doing much work. Then I realized that perhaps it didn't know how to get the job done and needed some help. Here's the list of things I did to help the defragmentor out: Relocate the paging file to a different drive and reboot. If the paging file ( pagefile.sys ) is seriously fragmented, it can't be defragmented, and in turn it blocks other files from being defragmented. If you only have one drive (C:), try to make it smaller or eliminate it entirely for...

You may choose to use a batch file for srvany (instead of plink.exe ), but you won't be able to shut down the tunnel when you stop the service. Also, if the Windows SYSTEM user cannot see the host key for SSH connection, the tunnel cannot be established.

Suddenly my Windows XP failed to boot with this error message on a blank screen: missing or corrupt <windows root>\system32\hal.dll I took out the hard drive, put it in a USB enclosure and attached it to another PC. Then I ran CHKDSK and it fixed some file system errors. But I did find that hal.dll was intact, so hal.dll was not missing or corrupt . It turned out that the file that was really missing was C:\boot.ini . It is a hidden file, so you have to use attrib boot.ini to see it. The file is missing if attrib boot.ini returns nothing (run in the root folder C:\). In my case I reconstructed the boot.ini file: [boot loader] timeout=30 default=multi(0)dis... and changed the attributes back...
