This app cannot open because of a company policy
Why does it say 'this app can't open' due to a company policy on my laptop?

Short answer
Windows has a set of rules that decide which programs are allowed to run. Those rules can arrive from a workplace, from Smart App Control, from a security app that installed its own policy, or from a leftover setting on a second hand computer. The wording mentions a company even when nobody at a company is involved, because the rule lives in the same place either way. The quickest thing to try first: check whether the laptop is genuinely managed — Open Settings, Accounts, Access work or school. If an organisation is listed there and you do not need it, select it and choose Disconnect. On a second hand or ex company laptop this single step removes most of these blocks. Most people are done in about 20 minutes.

Sounds like this
- •A message says the app was blocked by your system administrator
- •It mentions a company or organisation policy on a personal laptop
- •Nothing happens when you double click the program

Check whether the laptop is genuinely managed
Open Settings, Accounts, Access work or school. If an organisation is listed there and you do not need it, select it and choose Disconnect. On a second hand or ex company laptop this single step removes most of these blocks.

Look at Smart App Control
Open Windows Security, App and browser control, then Smart App Control settings. If it is On, it will silently refuse unsigned or unknown programs. Switching it to Off is permanent until you reinstall Windows, so only do it when you are sure the program is one you trust and downloaded from the maker's own site.
- 3
Unblock a file that came from the internet
Right click the installer, choose Properties, and if you see an Unblock tick box near the bottom of the General tab, tick it and press Apply. Windows marks downloaded files and some policies refuse anything carrying that mark.
- 4
Check reputation based protection
In Windows Security, App and browser control, open Reputation based protection settings and look at Potentially unwanted app blocking. Some free downloads carry bundled software and are blocked here rather than by any company rule.
- 5
Review your security software
Antivirus suites and parental control tools add their own application rules. Open the security app you use, find its blocked or quarantined list, and release the program from there rather than fighting Windows settings that are not the real cause.
- 6
Clear a leftover local policy
On Windows Pro press the Windows key and R, type gpedit.msc, and look under Computer Configuration, Windows Settings, Security Settings, Application Control Policies and Software Restriction Policies for rules you did not create. Delete only rules you recognise as leftovers. On Windows Home this editor does not exist, so use the earlier steps instead.
If none of that worked
If the laptop belongs to your employer or school, the block is deliberate and the people who manage it are the only ones who can lift it. Ask them rather than looking for a workaround, because bypassing the rule can breach the terms you agreed to when you accepted the device.
