Update QuickBooks Desktop Outdated versions often contain bugs and inefficiencies. 1. Open QuickBooks 2. Go to **Help > Update QuickBooks Desktop** 3. Click **Update Now** 4.

Close Background Applications Programs that consume RAM and CPU can slow QuickBooks: - Web browsers with many tabs - Cloud sync tools - Heavy antivirus scans - Other accounting software Closing these frees resources for QuickBooks. ### 6. Configure Antivirus & Firewall Security software may repeatedly scan QuickBooks files. Add exclusions for: - QuickBooks installation folders - Company file location - File extensions: `.QBW`, `.ND`, `.TLG` This prevents constant scanning delays. ### 7. Disable Unnecessary Startup Programs 1. Press `Ctrl + Shift + Esc` 2. Open the **Startup** tab 3. Disable programs not needed at boot This reduces system load and improves performance. ### 8. Repair QuickBooks Installation Corrupted program files can cause persistent slowness. - Open **Control Panel > Programs** - Select QuickBooks - Click **Uninstall/Change > Repair** - Restart after completion ### 9.
