TEHRAN (Press Shia) – Windows 10’s most significant upgrade to date is almost ready, but Microsoft has now issued an important warning for everyone who wants to get it.

In a new advisory, Microsoft has warned users that they will need up to twice as much free storage on their PCs to receive Windows 10 1903, the upgrade which finally gives all users control over Windows updates. The new requirement will apply to all versions of Windows 10: Home, Pro and Enterprise, Forbes reported.

The new minimum is 32 GB, double the previous 16 GB stipulation of 32-bit Windows 10 and almost 40% more than the 64-bit editions. For users with modern PCs this is unlikely to be a problem, but for older PCs (or users who consume a lot of storage), this could prove a more problematic hurdle with some finding they need to buy a new hard drive and migrate their data.

Moreover, Windows specialist Paul Thurrott believes Microsoft’s move will open the floodgates to far larger requirements in the near future, saying: “I’m surprised it took so long to get to 32 GB. And I see a 64 GB minimum happening in the near future.”

So if you have an older PC or simply don’t want to give up additional space equivalent to 4,000 12MP photos (source), should you just skip Windows 10 1903? In a word: No.
