## Frequently Asked Questions

Blackbird is stuck/hangs/crashes

It can take awhile (up to 1h, depending on system specifications and how much crap to remove) but if you're sure it's stuck, close Blackbird, open cmd as admin, cd to the directory where you put the blackbird.exe file. Type blackbird -V and hit enter. This should give you a more detailed view of what's going on. For further assistance you can reach us at

Blackbird shows errors like "access denied", "unable to read file", "system error"

This is normal, especially with Windows 10. Try closing and running Blackbird again, this somehow forces Windows to behave. Not sure why.

My antivirus reports Blackbird as malware

This appears to only happen with the 32bit version but we assure you, it's a false-positive.
We suspect this occurs because of the nature and relative obscurity of our software (registry editing,telemetry dismantling,..) Some temporary files are created during usage but they are all deleted before you even exit the program.

After running Blackbird I have problems connecting to my LAN. Do you even test, bro?

Blackbird, by default, applies some security tweaks (SMB user credentials leaking in this case) that may interfere with some networks. To fix LAN connectivity issues simply run Blackbird with the -L switch:
In CMD type blackbird -L after Blackbird has already been applied to your PC.

Startup scanner shows red stuff even after applying Blackbird. Why?

The scanner can be a little wonky, it may detect Blackbird was not fully applied for any of the following reasons:
- No internet connection. Either blocked by firewall or not available on your PC, Blackbird cannot resolve hostnames to IP addresses and block them effectively resulting in "Telemetry=Not Blocked".
- An aggressive AV blocked Blackbird from accessing system files/registry/settings. Not much we can do here, go with your gut.
- Certain Scheduled tasks are stubborn. Use the blackbird -STD switch to remove them.
- An update turned stuff back on. Check our website for an up-to-date version.
- Localization/other bugs with the scanner itself. Help us fix it by contacting us!

I don't like what Blackbird did to my computer. How do I change it back?

Start cmd as administrator, cd to the directory where you put the blackbird.exe file, type blackbird -R and press enter. This will run Blackbird in Recovery mode and will restore any and all changes made by Blackbird back to their default Microsoft values.
