Which? has called on Microsoft to honour the rights of its customers after a survey found that 12 per cent of those who upgraded to Windows 10 from an earlier version had rolled back and that many more were annoyed with the update.
More than half of those who rolled back to a previous edition said it was because the new version had caused problems with their devices.
The problems included printers, WiFi cards and speakers no longer working, files being lost and emails no longer syncing. In some cases the computer required professional repair.
Many complained that the only reason they upgraded in the first place was to get rid of the constant nagware employed by Microsoft through the GWX system installed on machines that qualified for a free upgrade.
Many said that they had actually turned down the nagware offers and found that Windows 10 had installed anyway.
Which? has called on Microsoft to improve its customer service and compensate customers as appropriate.
Among the complaints to Which? was that Microsoft has shown poor service when customers contacted the 'help' department.
Alex Meill, Which? director of campaigns and policy, said: “We rely heavily on our computers to carry out daily activities, so when they stop working it is frustrating and stressful. Many people are having issues with Windows 10 and we believe Microsoft should be doing more to fix the problem.”
Which? has reminded users that digital content such as Windows 10 is covered by the Consumer Rights Act 2015, and should be of satisfactory quality, fit for particular purpose and as described.
Customers can demand a repair or replacement or their money back, as well as damages for any loss caused.
Microsoft responded as follows: "The Windows 10 upgrade is a choice designed to help people take advantage of the most secure and most productive Windows.
"Customers have distinct options. Should a customer need help with the upgrade experience, we have numerous options including free customer support.”
