yesterday (3/19/2026 ) spouse told me he watched youtube how to verify computer whether got problems by [run (administrator) cmd typed perfmon /report] so i did and Diagnostic Results found Warnings: memory BUSY and Basic System Checks [The Security Center reports that User Access Control is disabled], same as spouse.

searched : how to solve [User Access Control is disabled.] in perfmon /report ?] To solve the "User Access Control is disabled" error in perfmon /report, you must re-enable User Account Control (UAC) via the registry or control panel, ensuring EnableLUA is set to 1. Alternatively, run Perfmon as an administrator, add your account to the "Performance Log Users" group, or rebuild counters using lodctr /r.
Here are the specific solutions:
1. Enable UAC (Fix "User Access Control is disabled")
If UAC is disabled, Perfmon cannot collect system diagnostics.
Via Control Panel: Type "UAC" in the Windows search bar, select Change User Account Control settings, and move the slider to the default (or higher) position.
Via Registry (if locked): Open regedit and navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
Locate EnableLUA and set its value to 1. Restart your computer.

Run Perfmon as Administrator
If UAC is enabled but you still get the error, open the Command Prompt or PowerShell as an Administrator, then run perfmon /report.
(Administrator) C:\Users\user-name >perfmon /report
............................. Not apply to Home Edition SKIP it 3. Add User to Performance Groups
If running as a standard user, you must be added to the necessary performance groups:
Open compmgmt.msc (Computer Management).
Go to System Tools > Local Users and Groups > Groups.
Double-click Performance Log Users and add your account.
Also add your account to Performance Monitor Users.
compmgmt.msc cant find [ Local Users and Groups]
Windows Home Edition, which does not include this feature

4. Rebuild Performance Counters PS not my case
If counters are corrupted, the report will fail:
Open Command Prompt as Administrator.
Type cd\windows\system32 and press Enter.
Type lodctr /r and press Enter to rebuild the counters
5. Check Service Status
Ensure the necessary services are running:
Open services.msc.
Verify Performance Logs & Alerts and Diagnostic Policy Service are set to "Automatic" and are currently running --i did [manual] changed to [automatic] on 03/19/2026

then restart PC , memory from [busy 77% 1868 MB Available] down to normal [65% 2801MB available] And Basic System Checks all passed.
