Return Codes
WuInstall uses the following return (exit) codes:
Code | Meaning |
0 | Successful, no reboot required |
1 | At least one error occurred, no reboot required |
2 | No more updates available |
3 | No updates available that match your search (in combination with /severity, /classification, /product, /criteria, /match, /nomatch, /matchfile, /nomatchfile) |
4 | Invalid criteria specified (in combination with /criteria) |
5 | Reboot/shutdown initialized successful (in combination with /reboot or /shutdown) |
6 | Reboot/shutdown failed (in combination with /reboot or /shutdown) |
7 | Syntax error, wrong command |
8 | Invalid version, expiration date reached |
10 | Successful, reboot required |
11 | At least one error occurred, reboot required |
12 | Timeout reached (in combination with /maxruntime) |
15 | Reboot cycle successful |
16 | Reboot cycle failed |
17 | Not enough disk space |
Use /simple_error to normalize all codes to 0 (success) or 1 (error). Use /extended_error for a bitmask return code with granular detail.
