I installed Sumatra PDF, MS Office 2007 (on external HDD), MBAM, VLC Media Player and uBlock.
I like the list of softwares you mentioned.EagleGet Download manager:
Sumatra Pdf reader is a great application for reading PDF files. (Foxit too is becoming bloated and takes much time in cold start.) and for other fancy features we have other commercial softwares.
Eagleget is another good free alternative to IDM.
I would suggest you to replace VLC by Daum Pot Player and ublock by ublock origin.
VLC sometimes struggles to play .mp4 files with serious lags in playback while sliding thorough the playing video. Well, it's a subjective opinion.
