PowerRename and RoundedTB are both Windows utilities, but they are designed for very different purposes. PowerRename is a bulk file renaming utility included with Microsoft PowerToys, while RoundedTB focuses on customizing the appearance and behavior of the Windows taskbar. Because their core functions are different, comparing them is mainly useful for understanding which type of Windows workflow each tool supports.
PowerRename provides search and replace, regular expressions, preview functionality, filtering, text formatting, and undo support for file and folder renaming. RoundedTB, meanwhile, adds taskbar margins, rounded corners, dynamic sizing, split layouts, and other taskbar customization options.

PowerRename Features
PowerRename is designed for users who need to rename multiple files or folders efficiently. It integrates with File Explorer, allowing selected items to be sent directly to the PowerRename interface from the Windows context menu. Users can enter search and replacement text and preview the resulting filenames before applying changes.
The utility also supports regular expressions for more advanced renaming operations. Additional options include filename or extension targeting, folder and subfolder inclusion, case formatting, enumeration, counters, and metadata-based variables. These features make PowerRename suitable for structured file organization, photo management, document cleanup, and other repetitive naming tasks.
RoundedTB Features
RoundedTB takes a completely different approach by modifying the visual presentation of the Windows taskbar. Its basic controls include taskbar margins and corner radius, allowing users to create a more separated or rounded taskbar appearance. Advanced controls provide independent margins for different sides of the taskbar.
RoundedTB also includes Dynamic Mode for Windows 11, which can resize the taskbar around its icons to create a dock-like appearance. Windows 10 users can use Split Mode, which provides a simpler way to separate the taskbar area from the system tray. The project also documents experimental compatibility with TranslucentTB.
Performance Comparison
PowerRename is primarily activated when a user performs a batch renaming operation, rather than continuously modifying the desktop. Its workflow is closely connected to Windows File Explorer and uses Windows file operation functionality for renaming, including support for undoing the operation.
RoundedTB interacts with the Windows taskbar continuously when its customization features are active. Its project history includes performance improvements and refactoring, but some advanced features have documented edge cases. For example, Dynamic Mode can occasionally fail to update correctly or become incorrectly sized, while experimental auto-hide behavior can cause flickering.
Compatibility and Requirements
PowerRename is part of Microsoft PowerToys, so its compatibility follows the supported Windows versions and architectures of the current PowerToys release. Current PowerToys documentation indicates support for Windows 10 version 2004 and later and Windows 11, with modern releases supporting x64 and ARM64 systems.
RoundedTB is specifically designed around Windows taskbar behavior. Its documented features cover Windows 10 and Windows 11, although some functionality differs between the two operating systems. Dynamic Mode is intended for Windows 11, while Split Mode provides a Windows 10-oriented alternative. Some advanced features also depend on the taskbar being positioned horizontally at the top or bottom of the display.
PowerRename Use Cases
PowerRename is particularly relevant when a user needs to process many filenames at once. A photographer might use it to standardize image names, while an office worker could use it to clean up document filenames or add consistent numbering to a collection of files.
It can also be useful for more technical workflows because regular expressions provide greater control over filename patterns. The preview window allows users to inspect expected results before making changes, which can reduce mistakes during large batch operations.
RoundedTB Use Cases
RoundedTB is intended for users interested in Windows desktop personalization rather than file management. It can change the spacing and shape of the taskbar and can create a more compact, segmented appearance through its Dynamic or Split modes.
Its usefulness is therefore concentrated around visual customization. Users who want a taskbar with additional margins, rounded corners, or a dock-inspired layout may find these controls relevant, while users looking for file management capabilities will find that RoundedTB serves a different purpose.

Which Workflows Do They Support?
The biggest difference between PowerRename and RoundedTB is their intended workflow. PowerRename is centered on file management and productivity, specifically the process of changing many filenames efficiently. RoundedTB is centered on desktop personalization, specifically the appearance and layout of the Windows taskbar.
As a result, the two utilities are not direct substitutes. A user organizing a large collection of files would encounter relevant functionality in PowerRename, whereas someone modifying taskbar spacing and shape would find RoundedTB more directly aligned with that task. Their different purposes make their feature sets complementary rather than directly interchangeable.
Ease of Use
PowerRename benefits from its integration with File Explorer. Once enabled in PowerToys, users can select files, open the context menu, choose PowerRename, configure the operation, and review the preview. Basic search-and-replace operations can therefore be relatively straightforward, while regex-based workflows require more technical knowledge.
RoundedTB also provides straightforward basic controls, particularly for margins and corner radius. Its advanced features require more configuration, and the project’s documentation notes that some advanced modes trade simplicity for additional customization. This creates a distinction between simple appearance changes and more involved taskbar layouts.
PowerRename vs RoundedTB: Key Differences
PowerRename focuses on manipulating filenames, whereas RoundedTB manipulates the presentation of the Windows taskbar. PowerRename is therefore associated with File Explorer and batch operations, while RoundedTB operates around the Windows desktop environment.
Their performance considerations also differ because they perform different jobs. PowerRename is generally used during individual renaming sessions, while RoundedTB can remain active as part of the desktop customization environment. RoundedTB’s advanced features have more documented taskbar-specific edge cases because they interact with Windows taskbar behavior.
