When you add comments to an Excel spreadsheet, you may be annoyed by the fact that your name doesn’t appear as the bolded commenter name by default. This revolves around the configuration of Excel, and the name that was supplied during the original installation process. This is especially true in corporate environments, where IT folks typically use imaging technologies to make all desktop systems the same.
Thankfully, changing Excel to supply your name in the header of a comment is easy enough. Just open Excel, click the Tools menu, select Options, and then click on the General tab. Towards the bottom of this window you’ll find an entry marked User name. Enter the name that you’d like to appear when you add comments to a cell, and then click OK. The next time you enter a comment in an Excel cell, the name that you entered will appear as the commenter name by default.
