How can I free up storage space

Hello Donald Alvarez,

Welcome to Microsoft Community.

If you want to free up some disk space for your Surface Book 1, I can recommend some relatively simple solutions here.

For example:

1. Release space through the storage awareness function of Windows system:

Manage drive space with Storage Sense - Microsoft Support ****

2. Free up space by disk cleanup:
3. In the search box on the taskbar, type disk cleanup, then select it from the results.
4. Select the drive you want to clean up files for, then select OK.
5. Select the check box next to the type of files you want to delete. (To view a description of each type of file, select the name.) By default, Downloaded Program Files, Temporary Internet Files, and Thumbnails are selected. Be sure to clear those check boxes if you don't want to delete those files.
6. To free up even more space, select Clean up system files, select a drive, select OK. When the system has done its calculations, select the type of system files you want to delete. Disk Cleanup will take a few moments to calculate the amount of space that can be freed up.
7. After you’ve selected the types of files you want to delete, select OK, and then select Delete files in the confirmation window to start the cleanup.
8. Transfer certain personal files to a removable hard drive or upload them to a cloud drive service, such as OneDrive or some of the cloud drive services you are using.

In addition, please allow me to share the official support link here, which may involve all other optional steps:

Finally, regarding telephone support, allow me to kindly explain to you. Because this model has been discontinued, out of warranty support and service for such models is no longer available. Therefore, there may be no phone support for your device.
