When writing documentation, or manuals or even training material sometimes you need a Windows logo. In the old days there used to be one in the WingDings font at character code 0xFF. The only problem now is that logo is a little out of date being more Windows 3.1 than Windows 10.
Fortunately deployed with Windows 10 is a font called “HoloLens MDL2 Assets” and this contains an up to date Windows logo at character code U+E782. Looking at this font it also contains lots of other quite useful computer or system related symbols.
