About this tag
The tag 'uncompressed' on WindowsForum.com relates to Windows Sandbox startup errors caused by virtual hard disk file requirements. In a specific thread, a user encountered error 0xc03a001a when launching Sandbox, with the system indicating that virtual hard disk files must be uncompressed and unencrypted and must not be sparse. The user's system root drive was formatted with NTFS compression, leading to the question of whether compression must be turned off to resolve the issue. This tag covers discussions about the necessity of uncompressed files for Windows Sandbox functionality and troubleshooting related virtual disk limitations.
