Systweak is an Indian technology company that makes various software tools for PCs and mobile devices. It specializes in system optimization, maintenance, and security software. RegClean Pro is one of its best-known products. 

The Windows Registry is a database that stores low-level settings for every PC running Windows OS. Redundant entries in this database could slow down your computer’s response time and general performance. Systweak’s RegClean Pro is a tool that detects and removes any such entries from your registry, ensuring optimal performance. 

We’re reviewing RegClean Pro to help you decide if it’s a suitable tool or not. Our review is based on specific criteria, including features, pricing, customer support, compatibility, etc.

Plans and pricing

Systweak’s RegClean Pro is freemium software with both a “free” and a “premium” version. The free trial version has limited features and is valid only for 24 hours. Hence, it’s ideal to pay for the premium version to make the best of the software. 

The premium version of RegClean Pro costs $40 for an annual license for one PC. You can get it on Systweak’s official website. Payment methods include PayPal or credit/debit cards. After paying, Systweak would send an activation key to your email to unlock all the software’s functionalities.

Systweak also offers a 60-day money-back guarantee for every purchase.


The core feature of RegClean Pro is scanning your PC’s Windows registry for any invalid entries and removing anyone it finds. Doing so helps your computer perform as efficiently as possible. 

Once you launch RegClean Pro, the visible “Start Registry Scan” button is the first feature you notice. Clicking this button begins the scan, which can take a few minutes. Afterwards, the app highlights the invalid entries in your registry and lets you delete them. You can delete them individually or collectively with the click of a button.

Note that the free trial version only lets you delete up to 15 invalid entries. You can see why the premium version is the ideal one.

RegClean Pro also lets you defragment your Windows registry. Defragmentation implies physically organizing the registry's contents in the smallest possible number of regions (or fragments). This way, any program on your PC referencing registry entries has fewer places to search through, thus working faster.

Regularly defragmenting your registry is ideal for keeping your computer in the utmost working conditions.

Registry Backup

The competition

RegClean has many competitors in the software market. One such competitor is Reviversoft Registry Reviver, a comprehensive registry optimization tool. It’s cheaper, costing $32 for a yearly subscription for one PC, compared to $40 for RegClean Pro. Its free version also offers more features than RegClean Pro’s. 

Final verdict

RegClean Pro is a perfect tool for detecting and eliminating any errors in your Windows registry. It helps your PC perform as optimally as possible. However, it has certain drawbacks, such as being relatively expensive.
