The methods below provide the best optimization results.<\/p>\n<h3>Method 1 \u2014 Disable Unnecessary Add-Ins<\/h3>\n<p>Add-Ins are one of the most common reasons why SOLIDWORKS starts slowly.<\/p>\n<ol>\n<li>Open:<br \/>\n<b>Tools \u2192 Add-Ins<\/b><\/li>\n<li>Disable <b>Start Up<\/b> for modules you do not use:\n<ul>\n<li>SOLIDWORKS CAM<\/li>\n<li>Composer<\/li>\n<li>Visualize<\/li>\n<li>Routing<\/li>\n<li>Simulation<\/li>\n<li>PDM<\/li>\n<li>Toolbox Browser<\/li>\n<\/ul>\n<\/li>\n<li>Click <b>OK<\/b><\/li>\n<li>Restart the program<\/li>\n<\/ol>\n<p>This alone can reduce startup time dramatically.<\/p>\n<h3>Method 2 \u2014 Optimize General Settings<\/h3>\n<ol>\n<li>Go to:<br \/>\n<b>Tools \u2192 Options \u2192 General<\/b><\/li>\n<li>Change:\n<ul>\n<li>\u201cOpen recent documents at startup\u201d \u2192 <b>Never<\/b><\/li>\n<li>Recent documents count \u2192 <b>10\u201320<\/b><\/li>\n<\/ul>\n<\/li>\n<li>Disable:\n<ul>\n<li>SOLIDWORKS sounds<\/li>\n<li>technical news and welcome notifications<\/li>\n<\/ul>\n<\/li>\n<li>Restart SOLIDWORKS<\/li>\n<\/ol>\n<p>This reduces unnecessary background loading during startup.<\/p>\n<h3>Method 3 \u2014 Graphics and RDP Optimization<\/h3>\n<p>If you use SOLIDWORKS through Remote Desktop, graphics effects can cause serious lagging and freezing.<\/p>\n<ol>\n<li>Open:<br \/>\n<b>Tools \u2192 Options \u2192 Performance<\/b><\/li>\n<li>Disable:\n<ul>\n<li>RealView Graphics<\/li>\n<li>Shadows<\/li>\n<li>Transparency<\/li>\n<li>Ambient Occlusion<\/li>\n<\/ul>\n<\/li>\n<li>For testing purposes, enable:<br \/>\n<b>Use Software OpenGL<\/b><\/li>\n<li>Restart SOLIDWORKS<\/li>\n<\/ol>\n<p>This often fixes black screens and performance issues over RDP connections.<\/p>\n<h3>Method 4 \u2014 Advanced SOLIDWORKS RX Troubleshooting<\/h3>\n<ol>\n<li>Launch:<br \/>\n<b>SOLIDWORKS RX<\/b><\/li>\n<li>Open:<br \/>\n<b>Safe Modes<\/b><\/li>\n<li>Try running SOLIDWORKS:\n<ul>\n<li>without OpenGL<\/li>\n<li>without settings<\/li>\n<li>without Add-Ins<\/li>\n<\/ul>\n<\/li>\n<li>If SOLIDWORKS stops freezing, the problem is most likely related to drivers or one of the enabled modules.<\/li>\n<\/ol>\n<p>This hidden troubleshooting tool helps identify startup problems without reinstalling the software.<\/p>\n<h3>Useful Tips<\/h3>\n<ul>\n<li>Install SOLIDWORKS on an SSD drive<\/li>\n<li>Add SOLIDWORKS folders to antivirus exclusions<\/li>\n<li>Avoid using unstable gaming GPU drivers<\/li>\n<li>Certified NVIDIA drivers usually work better with SOLIDWORKS<\/li>\n<li>Clean Windows temporary files regularly<\/li>\n<\/ul>\n<h3>Common Mistakes<\/h3>\n<p>Many users leave all Add-Ins enabled even if they never use them. This forces SOLIDWORKS to load unnecessary services every time it starts.<\/p>\n<p>Another common issue is running SOLIDWORKS on an HDD instead of an SSD. Large assemblies and drawings load much slower on traditional hard drives.<\/p>\n<p>Startup freezes also frequently appear after automatic GPU driver updates from Windows Update.<\/p>\n<h3>Frequently Asked Questions<\/h3>\n<h3>Why does SOLIDWORKS 2021 freeze during startup?<\/h3>\n<p>The most common reasons are unnecessary Add-Ins, problematic GPU drivers, or graphics settings.<\/p>\n<h3>What improves SOLIDWORKS performance the most?<\/h3>\n<p>Disabling unused Add-Ins and using an SSD drive provide the biggest performance improvements.<\/p>\n<h3>Can SOLIDWORKS run over Remote Desktop?<\/h3>\n<p>Yes, but it is recommended to disable graphics effects and enable Software OpenGL.<\/p>\n<h3>Will reinstalling SOLIDWORKS fix the issue?<\/h3>\n<p>Not always. In many cases, the problem is caused by settings or drivers rather than the installation itself.<\/p>\n<h3>What should I do if SOLIDWORKS freezes on the splash screen?<\/h3>\n<p>Try launching the software through SOLIDWORKS RX Safe Mode.<\/p>\n<h2>Conclusion<\/h2>\n<p>If SOLIDWORKS 2021 freezes on startup, you can usually fix the issue without reinstalling the software. The most effective solution is disabling unnecessary Add-Ins, optimizing graphics settings, and reducing background startup processes. For RDP environments and weaker PCs, disabling RealView and using Software OpenGL can significantly improve stability.<\/p>\n<hr \/>\n<h3>Read Also<\/h3>\n<ul>\n<li><a href=\"https:\/\/itexpert.top\/en\/windows\">WINDOWS<\/a><\/li>\n<li><a href=\"https:\/\/itexpert.top\/en\/it-blog\/computer\">Computer<\/a><\/li>\n<li><a href=\"https:\/\/itexpert.top\/en\/it-blog\/video-card\">Video Card<\/a><\/li>\n<li><a href=\"https:\/\/itexpert.top\/en\/it-blog\/upgrade\">Upgrade<\/a><\/li>\n<li><a href=\"https:\/\/itexpert.top\/en\/it-blog\/openai\">OpenAI<\/a><\/li>\n<\/ul>\n<h3>Bookmarks<\/h3>\n<p>If this article was useful for you, bookmark our blog about<br \/>\n<a href=\"https:\/\/itexpert.top\/en\/it-blog\/computer\">computer software and Windows optimization<\/a>.<\/p>\n<p>Press <b>Ctrl + D<\/b><\/p>\n","protected":false},"excerpt":{"rendered":"<p>SOLIDWORKS 2021 Freezes on Startup \u2014 How to Speed It Up and Fix the Problem Short description: A detailed guide on how to fix SOLIDWORKS 2021 startup freezes, improve performance, disable unnecessary modules, and optimize the software even for remote &hellip; <\/p>\n","protected":false},"author":1,"featured_media":20729,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"slim_seo":{"title":"SOLIDWORKS 2021 Freezes on Startup - ITexpert","description":"SOLIDWORKS 2021 Freezes on Startup \u2014 How to Speed It Up and Fix the Problem Short description: A detailed guide on how to fix SOLIDWORKS 2021 startup freezes, i"},"footnotes":""},"categories":[48,190,53,153],"tags":[],"class_list":["post-20733","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-it-blog-en","category-programs","category-windows-10-en","category-windows-11-en"],"_links":{"self":[{"href":"https:\/\/itexpert.top\/en\/wp-json\/wp\/v2\/posts\/20733","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/itexpert.top\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/itexpert.top\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/itexpert.top\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/itexpert.top\/en\/wp-json\/wp\/v2\/comments?post=20733"}],"version-history":[{"count":2,"href":"https:\/\/itexpert.top\/en\/wp-json\/wp\/v2\/posts\/20733\/revisions"}],"predecessor-version":[{"id":20735,"href":"https:\/\/itexpert.top\/en\/wp-json\/wp\/v2\/posts\/20733\/revisions\/20735"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/itexpert.top\/en\/wp-json\/wp\/v2\/media\/20729"}],"wp:attachment":[{"href":"https:\/\/itexpert.top\/en\/wp-json\/wp\/v2\/media?parent=20733"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/itexpert.top\/en\/wp-json\/wp\/v2\/categories?post=20733"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/itexpert.top\/en\/wp-json\/wp\/v2\/tags?post=20733"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
