The user, Teri Goldstein, runs a travel agency in Sausalito, a San Francisco Bay Area city in Marin County, California.
She told the newspaper that her computer began trying to download Windows 10 a few days after the updated operating system was released to consumers last year.
Goldstein said she had not authorised the update and after this, her computer slowed to a crawl. It would also crash frequently.
In her lawsuit Goldstein sought damages to cover lost wages and the cost of a new PC.
In May, Microsoft paid out US$10,000 after halting an appeal.
As iTWire has reported, the only way to prevent a forced upgrade of Windows 10 taking place on systems that run Windows 7, 8 or 8.1 is to turn off automatic updates.
That, however, puts a system at risk as security updates to fix what are serious flaws need to be installed as soon as possible and this is best managed by leaving updates to occur automatically.
