This means that anyone in the U.S. who upgraded from Windows 7 (Windows 8 would not be included under this motion) and who has suffered any of the symptoms described within 30 days could join in.
More than 2 years since its initial launch, the Windows Insider program now has 10 million users all around the world.
Three Illinois residents are leading a class-action suit against Microsoft over data loss and damage to their computers, which they blame on the Windows 10 upgrade.
We have contacted Microsoft for its views on the class action but have yet to receive a response. Last June a woman in California was offered $10,000 after her computer was borked by the update.
Microsoft released Windows 10 in July 2015, and then for a year, it offered users of Windows 7 and 8 a free upgrade to Windows 10.
One of the plaintiffs describes in the filing how he regularly selected no on the prompts for him to update to Windows 10 but after six months, he eventually gave in. Plaintiffs complain that the ads were too hard to uninstall and didn't allow them to refuse the upgrade or keep the ads from popping up again.
Last year, a United States small claims court ruled that Microsoft should pay $10,000 to Teri Goldstein, a travel agent based in Sausalito, California, who said an unwanted Windows 10 upgrade made her PC unstable. Goldberg paid someone to fix the computer since the hardware was out of warranty and is claiming lost data, lost time and money, and loss of the use of his computer.
In the USA a lawsuit has been aimed against Microsoft which accuses Windows 10 of damaging PCs and causing users to lose data. Robert Saiger, another plaintiff, made a decision to upgrade to the new OS but his other software stopped working after the upgrade.
With all these complaints, Microsoft has dismissed the claims as without merit. They allege that while the Windows 10 installer genie checks PCs for compatibility, it does not consider the condition of the system or make any attempt to see if the hard drive "can withstand the stress of the Windows 10 installation". Plaintiffs in the lawsuit allege that after upgrading, which in some cases occurred without their permission, their PCs were inoperable, forcing them to either pay for repairs or upgrade to a brand new system.
