HowTo: Fix DVD/CD with Live filesystem (Packet/UDF) on Windows 10 Οκτωβρίου 18 09:33 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια: The other day I found how easy it is to use a Live CD/DVD (where packet writing occurs when adding stuff) instead of a Mastered one (where all is kept to be written when you close the disk) on Windows.

HowTo: Download and install Windows Live Movie Maker 28 Μαρτίου 18 08:00 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια: Unfortunately, Microsoft seems to have gone to extra lenghts to make the Windows Live suite of software go away, without anyone thinking that there were people who were using them and without offering file/project-level compatible replacements for user-friendly tools like Windows Live Movie Maker. Only Windows Live Writer was at some point reincarnated as the […]
