Symptom
Section titled “Symptom”Error code 0x80070005 appears in XBOX apps, Microsoft Store, Windows Update or when installing programs. The code itself means “Access denied”: a program or service cannot write a file where it is trying to.
Typical causes
Section titled “Typical causes”- NTFS permissions on the system temporary folder have been lost: updates, XBOX apps and installers cannot create temporary files. A typical scenario is aggressive “cleaners”, tweaks and manual experiments with permissions.
Fix in BoosterX
Section titled “Fix in BoosterX”Open BoosterX → “Fixes” (in the left menu) → in the search field enter “Error 0x80070005 in XBOX, Windows Update, etc.” → “Fix” → restart Windows. The fix restores permissions on the system temporary folder — it eliminates program and update installation errors.
BoosterX can be downloaded from the official website boosterx.org.
How to verify
Section titled “How to verify”Repeat the action that ended with code 0x80070005: checking for updates, installing or updating an XBOX app.
Manual alternative without BoosterX
Section titled “Manual alternative without BoosterX”The same as for errors 2502 and 2503 when installing programs: manually check the permissions on the C:\Windows\Temp folder via “Properties” → “Security” and compare with a reference Windows.
If it did not help
Section titled “If it did not help”Code 0x80070005 is common to many access failures: if the permissions on the temporary folder are fine, the cause is elsewhere. Collect the event log via EventX and contact support.
