This may outcome in a "Windows needs more space" dialog box, or one of several error codes (including 0x80070070 – 0x50011, 0x80070070 – 0x50012, or 0x80070070 – 0x60000).

Fourth dimension's running out to clear some space and complete the installation. Here'southward what y'all tin can exercise to make sure the upgrade goes through:

Windows x: How much space you need

While the install files for Windows 10 have up simply a few gigabytes, going through with the installation requires a lot more space. According to Microsoft, the 32-bit (or x86) version of Windows x requires a total 16GB of free space, while the 64-bit version requires 20GB. (To come across which version you're running, open the Control Panel, click on System, then look under the "System type" label.)

On some devices, such every bit Windows ten tablets with only 16GB or 32GB of storage, Windows may perform a compressed installation. This but requires 8.5GB of free space. In whatsoever case, Windows will tell you how much additional space it needs when the "Windows needs more than space" dialog appears.

How to free up storage space for Windows 10

The simplest way to reclaim storage infinite in Windows is through Disk Cleanup. Head to File Explorer, then right-click on the C: drive, and click Properties. Nether the General tab, select Disk Cleanup. Windows will locate temporary files, Recycle Bin files, and error-related data that it can discard. Some of these files and data will be selected for removal by default, merely exist sure to also check the box for "System fault memory dump files," as these are fairly prophylactic to remove and can be storage hogs.

If Deejay Cleanup doesn't requite you plenty space, and yous'd rather not touch on the files and programs that are on your hard drive already, yous tin can connect an external drive or select a secondary hard drive to finish the installation. External storage can include a USB stick, external hard drive, or MicroSD card. The amount of infinite required on that bulldoze will depend on the system, but you shouldn't need any more 16GB in any case.

To use an external bulldoze, proceed with the installation until you reach the "Windows needs more space" screen, and so select Choose another bulldoze or adhere an external drive. Select the drive yous desire to use from the drop-down menu.

One affair to remember: When choosing this option, your previous version of Windows will exist stored on the external bulldoze, under a binder called Windows.sometime. Should you decide that Windows 10 isn't for yous, you lot'll have to connect the external bulldoze to roll back to Windows vii or Windows 8.
