Frequently Asked Questions

Does this mean my Store apps are all broken?

Not necessarily all of them — this error is usually specific to the app or package currently being installed or updated, not the whole Store system.

Will re-registering fix future updates too, or just this one?

Re-registering the affected package generally fixes both the current issue and future updates for that specific app, not just a one-time patch.

Other error codes

0X80070005 — Access Denied

A permissions problem — the current user account doesn't have rights to the file, folder, or action being attempted.

0XC0000022 — STATUS_ACCESS_DENIED

A related but technically distinct code from the more common 0x80070005 — this is the NTSTATUS-style access-denied error, most often seen when a program can't open a file, DLL, or registry key it needs at startup, or when Windows activation specifically fails because the Software Protection Service can't start.

0X8007000E — Not Enough Storage / Out of Memory

Despite the wording, this is usually about low disk space rather than RAM — an operation ran out of room to complete.

0XC0000005 — Access Violation (STATUS_ACCESS_VIOLATION)

A program tried to read or write memory it wasn't allowed to — usually an app bug, but can indicate corrupted files or faulty RAM if it happens across many different apps.
