The error "This operation has been cancelled because of restrictions on the computer" is usually caused by permissions or policy restrictions. Solutions include: 1. Check whether to use an administrator account, and if not, switch or change the account type; 2. Run the program as an administrator, or set a shortcut to always run as an administrator; 3. Check Group Policy restrictions, set suspicious policies to "not configured" or "disabled", but be careful that there is no Group Policy Editor for the Home Edition; 4. If registry editing is disabled, you can re-enable it by creating a .reg file; 5. Troubleshoot third-party software interference, temporarily close the security software or management startup items. Trying the above methods in order usually solves the problem.

You're trying to do something on your Windows PC, and suddenly you see the message: "This operation has been cancelled due to restriction in effect on this computer." It's frustrating, especially if you're not sure what's causing it. The good news? This issue usually comes down to a few common causes — and there are straightforward fixes.

1. Check If You're Using a Standard User Account

One of the most common reasons for this error is that you're logged into a standard user account instead of an administrator account. Some system-level actions can only be performed with admin rights.

What to do:

• Press Win I to open Settings.
• Go to Accounts > Family & other users (or Other users depending on your Windows version).
• Look under “Your info” to see if your account type says “Administrator.”
• If not, switch to an admin account or change your current account type to admin.

Keep in mind: Changing account types require you to already have access to an admin account.

2. Run Programs as Administrator

Even if you're using an admin account, some operations still need elevated permissions. Trying to access certain system files or tools without elevation can trigger this error.

How to fix:

• Right-click the app, shortcut, or installer you're trying to run.
• Choose Run as administrator from the context menu.
• If prompted by UAC (User Account Control), click Yes to continue.

If you frequently use specific programs and keep running into this issue:

• Right-click the program shortcut > Properties > Shortcut tab > Advanced .
• Check Run as administrator , then click OK.

3. Group Policy Restrictions Might Be Blocking You

If you're on a work or school computer, the IT department may have applied policies that limit what users can do. Even on personal PCs, misconfigured settings or third-party software can alter these policies.

Check local group policy:

• Press Win R , type gpedit.msc , and hit Enter.
• Navigate to User Configuration > Administrative Templates > System > Ctrl Alt Del Options or similar sections.
• Look for any enabled policies like “Remove Task Manager” or “Prevent access to registry editing tools.”

If you find anything suspicious:

• Double-click the policy and set it to Not Configured or Disabled .
• Reboot your PC after making changes.

Note: Not all Windows versions include the Local Group Policy Editor — it's missing in Home editions.

4. Registry Editing May Be Disabled

Sometimes, this error pops up when you try to open the Registry Editor ( regedit ). It might have been disabled via a policy or registry tweak.

Try enabling it:

• Open Notepad and paste the following:

 Windows Registry Editor Version 5.00

[HKEY_CURRENT_USERThis operation has been cancelled due to restrictions in effect on this computer Windows fixSoftwareThis operation has been cancelled due to restrictions in effect on this computer Windows fixPoliciesThis operation has been cancelled due to restrictions in effect on this computer Windows fixMicrosoftThis operation has been cancelled due to restrictions in effect on this computer Windows fixWindowsThis operation has been cancelled due to restrictions in effect on this computer Windows fixSystem]
"DisableRegistryTools"=dword:00000000

• Save it as enable-regedit.reg (make sure it ends in .reg ).
• Double-click the file and confirm the change.
• Restart your PC and try opening Regedit again.

5. Third-Party Software Could Be Interfering

Some antivirus programs or system utilities block certain operations they consider risk. That includes even harmless tasks like editing the hosts file or launching scripts.

What to try:

• Temporarily disable your antivirus or endpoint protection tool.
• Try the operation again.
• If it works now, add an exception for that action or file in your security software.

Also, check if any startup apps are interfering:

• Press Ctrl Shift Esc to open Task Manager.
• Go to the Startup tab and disable non-essential apps one by one.

Fixing the “operation has been cancelled” error often comes down to permissions or policies. Start with checking your account type and running things as admin. If those don't help, dig into group policies or registry settings. And don't forget to consider third-party tools — they sometimes block things quietly.

Basically that's it.
