Microsoft Ads is one of the least popular new features in Windows 10 that is directly injected into its operating system. This ad shows up in a number of ways, just like what happened specifically in File Explorer, when Windows 10, in particular, that is started by nagging people to buy the subscription to One Drive.

According to Extreme Tech, Microsoft's OneDrive cloud is a Windows 10 built-in storage that is tied up on the Microsoft account. Everyone will get a 5GB of free OneDrive storage, but it can be easily upgraded by paying to get a 1TB for a single user that will include an Office 365 subscription.

The said ad will appear at the top of File Explorer as a banner, reminding that OneDrive and Office 365 can be purchased for $6.99 per month. The users can take the Microsoft's offer or dismiss it, but it will just reappear at a later date.

By turning off the OneDrive ads, in File Explorer go to View menu, then Options and select "Change folder and search options." In the next window, the user can then select the View menu and uncheck the "Show sync provider notifications" option, as indicated by Digital Trends report.

Unfortunately, this is not the first time for Microsoft to crammed ads into its Windows UI. There are some lock screen ads that disguised as backgrounds, notification ads for Edge, and a weird pop-up ad for Microsoft's shopping assistant in Chrome.

It is odd that Microsoft has suddenly become so enchanted with the ads in Windows 10. But if the user is persuaded by the ads, they can sign up for an Office 365 Personal subscription that gives 1TB of OneDrive space for $70 per year for one PC, and a $100 per year for five PCs, which will receive the same 1TB of OneDrive storage. Though individuals will pay for Windows, even if it has a free upgrade, it is surely at least pay for Windows license on PC.
