From Nightwish‘s (symphonic metal) 2011 album, Imaginaerum, comes the “Burton-y”-est song yet…
List all files a particular string occurs in

Skip Avira’s Free Antivirus reboot request on updates

Using rsync to syncronize files between two systems
Rsync is a very handy tool at synchronizing the contents of two folders/directories.

Clone partition table to new disk
When replacing a failed RAID1 member from the array, setting up the replacement disk requires to partition it exactly as the existing disk. But this takes time to do manually…

Dismount mounted drives that do not have letters in Computer Manager
Upon entering Computer Manager to remove the drive letters, the partitions do not have any letters assigned. In fact, no actions beside “Delete partitions” are present on the context menu. But the partitions show up in Windows Explorer as drives H: and K.
Luckily MOUNTVOL, a Windows utility (present in all Windowses since Xp) “creates, deletes, or lists a volume mount point”.
